TECHNICAL INFORMATION Laboratory works require apparatus made in a Borosilicate 3.3 expansion glass which offers maximum inertness to widest range of chemical substances, withstand thermal shock, high temperature without deforming and resilient enough to withstand the normal laboratory handling, washing and sterilizing processes. Borosilicate glass represents unmatched standardized glass for construction of Laboratory Glasswares. Its steadly growing use is due to many advantages over conventional materials. ● Outstanding corrosion resistance ● Smooth pore and surface. ● Transparency ● Catalytic, inertness ● No effect on taste and odour ● Physiological inertness Borosilicate glass is chosen for its unique chemical and physical properties. Borosilicate glass can be considered as being composed of oxides. Silica (SiO , boric oxide (B O ) and phosphorous 2 pentoxide (P O5) are chief glass form oxides.Soda (Na O),Lime (CaO),Alumina (AI O ) Potash (K O) 2 2 2 3 2 Magnesia (MgO) and lead oxide (PbO) are the principle modifiers/fluxes. CHEMICAL COMPOSITION The composition of borosilicate glass used has following approximate composition. SiO -80.6% B O -12.5% 2 23 Na O-4.5% AI O -2.2% 2 23 RESISTANCE TO CHEMICALS Borosilicate glass is inert to almost all materials except hydrofluoric acid (HF) phosphoric acid (H PO ) and hot strong caustic solutions. Of these, Hydrofluoric acid has the most serious effect, 3 4 even when it is present in PPM (parts per million) in solutions, Whereas phosphoric acid and caustic solutions cause no problems when cold but at elevated temperature corrosion occurs. In case of caustic solutions upto 30% concentration can be handled safely at ambient temperature. Under actual operating conditions, the effect of turbulance, and traces of other chemicals in the solution may increase or decrease the rate of attack. So it is not possible to give exact figures for corrosion by caustic solutions. THERMAL PROPERTIES Linear coefficient of thermal expansion the coefficient of thermal expansion of borosilicate glass 7 over the temperature 0-300 °C is 33 x 10 / °C.This is very low when compared with other glasses and metals.That is why borosilicate glass is often called low expansion borosilicate glass. 2 3 3 SPECIFIC HEAT Specific heat between 25°C and 300 °C is average to be 0.233Kcal/Kg °C. THERMAL CONDUCTIVITY Thermal conductivity is 1.0 Kcal/hr.m°C over the permissible operating temperature range. ANNEALING Annealing of glass is the process where the glass is heated and kept for a defined period of time to relieve internal stresses. Careful cooling under controlled conditions is essential to ensure that no stresses are reintroduced by chilling/cooling. MECHANICAL PROPERTIES The lack of ductility of glass prevents the equalization of stresses at local irregularities or flaws and the breakage strength varies considerably about a mean value. This latter is found to occur at a tensile strength of about 700kgs/cm. In order to allow for the spread of breaking stress, a large factor of safety is applied when determining the wall thickness requirement to allow operation up to specified limit of working pressure. OPTICAL PROPERTIES Borosilicate glass shows no appreciable absorption in the visible region of spectrum and therefore appears' clear and colorless. In photo chemical process the transparency of ultra violet is of particular importance. It follows from the transmittance of material in UV region that photochemical reactions such as chlorination & sulpho-chlorination can be performed in it. 4 CAREANDMAINTENANCE SAFE USE OF GLASSWARE When heated with proper care Laboratory Glasswares will give long and satisfactory service. The following notes assist users in obtaining the maximum life and performance from their Laboratory Glassware. HEATING AND C00LING Glass may suffer damage in three ways : It may break under thermal stress in the 'steady state'. It may break under sudden heating or cooling. Glass if heated beyond certain temperature, may acquire a permanent stress on cooling which could cause subsequent failure. The following suggestions will help in avoiding failures during heating and cooling procedures. 1. During evaporation, never leave vessel unattended. Lower the temperature gradually as the liquid level drops, to avoid dryness condition, otherwise glass vessel may crack or explode. 2. Always use caution when placing heated vessel on a cold or damp surface. Sudden temperature may cause the vessel to break. 3. Always cool vessels slowly to avoid thermal breakage. 4. Never apply heat to badly scratched or etched vessel to prevent chance of breakage. 5. Avoid point source of heating to a vessel and always diffuse it by using ametal guage or air/water bath. Alternatively ensure uniform heating of the vessel by slow movement of the vessel in relation to he heat source. 6. Uniform heat is critical factor for some chemical reactions. For this adjust large soft flame of Bunsen burner to heat slowly but also more uniformly. 7. Adjust the flame contacts and heat the vessel below the liquid level to avoid breakage of the vessel. 8. Always use anti-bumping devices in the vessel, such as pumice or glass wool when rapid heating of the vessel and contents is required and to prevent internal abrasions of the vessels. 9. Thick walled glasswares are best heated with the use of an electric immersion heater and should not e subjected to direct flame or other localised heat source. 10. Do not heat glassware's over electric heaters with open elements to avoid localised stress and chances of breakage. 11. Always ensure that the surface of the hot plate is larger in area than the base of the vessel being heated to prevent uneven heating and glassware breakage. 12. When using electrical appliances always ensure to follow manufacturer's instructions. MIXING AND STIRRING 1. To prevent scratching the inside of a vessel always use a 'policemen' or similar evice on stirring rods 2. When using a glass vessel with a magnetic stirrer always uses a severed follower to prevent abrading the inside of the vessel. 5 3. Before using glass or metal mechanical stirrer in a glass vessel, predetermine the height of the stirrer to ensure there is no contact between the stirrer blades and the bottom or sides of the vessel. 4. Never mix sulphuric acid and water inside a glass-measuring cylinder. The heat of reaction can break the base of the cylinder. VACUUMAND PRESSURE 1. Always follow safety measures when working with glassware subjected to pressure or vacuum. 2. Never use glassware beyond the recommended safe limit. 3. Gradually apply and release positive and negative pressures and never subject to sudden pressure changes. JOINING AND SEPARATING GLASS APPARATUS 1. When storing glass stopcocks and joints insert a thin strip of paper between joint surfaces to prevent sticking. 2. Never store stopcocks for long periods with lubricant still on the ground surfaces. 3. Glass stopcocks on Burettes and Separating Funnels should be lubricated frequently to prevent sticking. 4. If a ground joint sticks, the use of penetrating oil will often prove useful in helping separation. Carefully rocking the cone in the socket or gently tapping the socket flange on a wooden surface can generally achieve separation. 5. In using lubricants it is advisable to apply a light coat of grease completely around the upper part of the joint and avoid greasing that part of the joint, which contacts the inner part of the apparatus. 6. (a) Hydrocarbon grease are commonly used on standard taper joints. Most laboratory solvents, including acetone,can easily remove it. (b) For higher temperature or high vacuum applications, silicon grease is often preferred and it can be removed readily with chloroform. (c) For long term reflux or extraction reactions, glycerin grease is suitable and it is soluble in water. 7. Wear heavy protective gloves when inserting glass tubing into a bung. The use of water, oil or glycerol is recommended on both tubing and rubber bung while carrying this operation. PERSONAL SAFETY 1. To prevent accidents use tongs or asbestos gloves to remove all glassware from heat source. 2. Follow safety measures. 3. Before opening Acid bottle, always flush the outside of bottlewith water. 4. All mercury containers should be kept well stoppered. Mercury toxicity is cumulative and element's ability to amalgamate with a number of metals is well known. 5. Never taste or smell chemicals for identification and never drink from a beaker. 6. When using concentrated acids, alkalies or potentially hazardous materials use mechanical means or pipeting.Avoid pipeting by mouth. 7. Label all containers before filling. Never fill unlabeled containers and throw away contents of unlabeled containers. 8. Do not look down into a test-tube to avoid any type of accident while test tube being heated or containing chemicals. 9. Do not permit glass-to-metal contact when clamping glassware, and do not excessively tighten the clamps to avoid breakages. 6 10. Splattering from acids, caustic materials and strong oxidizing solutions on the skin or clothing should bewashed off immediatelywith large quantities of water. 11. When working with chlorine, hydrogen, sulphide, carbon monoxide, hydrogen cyanide and other very toxic substances, always use a protective mask or perform these experiments under a fume hood in awell-ventilated area. 12. In working with volatile materials, remember that heat causes expansion and confinement of expansion results in explosion. 13. Perchloric acid is especially dangerous because it explodes on contact with organicmaterials. Do not use perchloric acid around wooden benches or tables. Keep perchloric acid bottles on glass or ceramic trays having enough volume to hold all the acid in case the bottle breaks.When using perchloric acid, always wear protective clothing. 14. When using hot plates and other electrical equipments, ensure the wire and plugs are in good condition. Never handle electrical connection with damp hands. CLEANING Successful experimental results can only be achieved by using a clean apparatus. In all instances laboratory glassware must be physically clean, in nearly all cases it must be chemically clean and in specific cases it must be bacteriological clean or sterile. There must be no trace of grease and safest criteria of cleanliness are the uniform wetting of the glass surface by distilled water. Any prevention of uniform wetting of the surface will introduce errors such as distortion of the meniscus and accuracy of volume. GENERAL CLEANING 1. Experienced personnel must solely undertake, cleaning of glassware, which contain hazardous materials. 2. Most new glassware is slightly alkaline in reaction. For precision chemical tests, new glassware should be soaked several hours in acid water (1% solution hydrochloric acid or nitric acid) before washing. 3. Glassware, which is contaminated with blood clots, culture media, etc., must be sterilized before cleaning. 4. If glassware becomes unduly clouded or dirty or contains coagulated organic matter, it must be cleaned with chromic acid cleaning solution. The dichromate's should be handled with extreme care because it is a powerful corrosive. 5. Wash glassware, as quickly as possible after use but if delays are unavoidable, the articles should be allowed to soak in water. 6. Grease is removed by weak sodium carbonate solution or acetone or fat solvents. Never use strong alkalis. 7. Hot water with recommended detergents should be used and if glass is exceptionally dirty a cleaning powder with a mild abrasive action can be applied - provided the surface is not scratched. 8. During the washing all parts of the article should be thoroughly scrubbed with a brush selected for the shape and size of the glassware. Brushes should always be in good condition to avoid any abrasion of the glassware. When chromic acid solution is used, the item may be rinsed with the cleaning solution or it may be filled and allowed to stand-the amount of time depending on amount of contamination on the glassware. 7 9. Special types of precipitate material may require removal with nitric acid, aqua regia or fuming sulphuric acid.These are very corrosive substances and should be used onlywhen required. 10. It is imperative that all soap detergents and other cleaning fluids be removed from glassware before use. This is especially important with the detergents, slightly traces of which will interfere with serological and culture reactions. After cleaning, thoroughly rinse with tap water ensuring that containers are partly filled water, shaken and emptied several times. Finally rinse with demonized or distilled water. 11. Drying can be undertaken either in baskets or on pegs in air or at a temperature not exceeding 120 °C. 12. Always protect clean glassware from dust by use of temporary closures or by placing in a dust free cabinet.For cleaning Specific type of glassware, please refer the following pages CLEANING SPECIFIC TYPES OF GLASSWARE PIPETTES 1. Place pipettes tips down, in a cylinder or tall jar of water immediately after use. Gently place it on a pad of cotton or wool to prevent breaking of the tips. At a convenient time, the pipettes may then be drained and placed in a cylinder or jar of dissolved detergent or, if exceptionally dirty, in a jar of chromic acid cleaning solution. After soaking for several hours, or overnight, drain the pipettes and run tap water over and through them until all traces of dirt are removed. Soak the pipettes in distilled water for at least one hour. Remove from the distilled water, dry the outside with a cloth shake out the water and dry. 2. In laboratories where a large number of pipettes are used daily, it is convenient to use an automatic pipette washer. Polyethylene baskets and jars may be used for soaking and rinsing pipettes in chromic acid cleaning solution. 3. After drying, place pipettes in a dust-free drawer.Wrap serological and bacteriological pipettes in paper or place in pipette cans and sterilize in the dry air sterilizer at 160 °C for two hours. Pipette used for transferring infectious material should have a plug of cotton placed in the mouth end of the pipette before sterilizing BUERETTES (WITH GLASS STOPCOCK) 1. Remove the stopcock key and wash the burette with detergent and water. 2. Rinse with the tap water until all the dirt is removed.Then rinse with distilledwater and dry. 3. Wash the stopcock key separately. Before the stopcock key is replaced in the buerette, lubricate the jointwith a small amount of lubricant. REMEMBER THAT BURETTE STOPCOCK KEYS ARE NOT INTERCHANGEABLE. 4. Always cover burettes when not in use. CULTURE TUBES 1. Culture tubes, which have been used, previously must be sterilized before cleaning. The best general method for sterlising culture tubes is by autoclaving for 30 minutes at 121°C (15 Ib. pressure). Media that solidify on cooling should be poured out while the tubes are hot. After the tubes are emptied, brush with detergent and water, rinse thoroughly with tap water, rinse with distilledwater, place in a basket and dry. 8 2. If tubes are to be filled with a medium, which is sterilized by autoclaving, do not plug until the medium is added. Both medium and tubes are thus sterilized with one autoclaving. 3. If the tubes are to be filled with a sterile medium or if they are to be sterilized by the fractional method and sterilize the tubes in the autoclaves or dry air sterilizer before adding the medium. SEROLOGICALTUBE 1. Serological tubes should be chemically clean but need not be sterile. However, specimens of blood, which are to be kept for some time at room temperature, should be collected in a sterile container. Itmay be expedient to sterilize all tubes as routine. 2. To clean and sterilize tubes containing blood, discard the clots in a waste container and place the tubes in a large basket. Put the basket with others, in a large bucket or boiler. Cover with water, add a fair quantity of soft soap or detergent and boil for 30 minutes. Rinse the tubes and clean with brush, rinse and drywith the usual precautions. 3. It is imperative when washing serological glassware that all acid, alkali and detergent be completely removed. Both acid and Ikali in small amounts destroy complement and in large amounts produce hemolysis. Detergents interfere with serological reactions. 4. Serological tubes and glassware should be kept separate from all other glassware and used for nothing except serological procedures. DISHES AND CULTURE BOTTLES 1. Sterilize and clean as detailed under CultureTubes. 2. Wrap in heavy paper or place in a petri dish can. 3. Sterilize in the autoclave or dry air sterilizer. 9 INDEX A ADAPTORS, ENLARGING, INTERCHANGEABLE JOINTS ADAPTORS, REDUCING, INTERCHANGEABLE JOINTS B BEAKERS BERZEUUS.TALL FORM,WITH SPOUT BEAKERS BERZELIUS.TALL FORM,WITHOUT SPOUT BEAKERS GRIFFIN.LOW FORM.WITH SPOUT.GRADUATED BEAKERS PHILIPS, CONICAL, WITH SPOUT BOTTLES, ASPIRATOR ,WITH INTERCHANGEABLE STOPPER AND STOPCOCK BOTTLES, ASPIRATOR WITH OUTLET FOR STOPPER BOTTLES, ASPIRATOR WITH OUTLET FOR TUBING BOTTLES, B.O.D WITH INTERCHANGEABLE STOPPER BOTTLES, GAS WASHING , COMPLETE WITH INTERCHANGEABLE STOPPER BOTTLES, ONLY FOR GAS WASHING BOTTLES CAT.
