Amber glassware is borosilicate, but ranks as ASTM, Type I, Class B due to the addition of material for theamber coloring. Borosilicate glass that is called 50 or 51COE is used in some apparatus and in some disposableglass products. That is also ASTM, Type I, but is Class Bborosilicate. Soda lime which is only used for a coupledisposable products or a bottle, is classified as ASTM,Type III glass.

GLASS HANDLING & SAFETY

6 844.817.8714

CARE AND HANDLING OFBOROSILICATE GLASSAlways inspect your glassware before use, even whenpurchased new. Bumping of glass in transit or in washingis always possible, and this can cause small fractures orstar cracks. You can usually see these when you hold thevessel up to normal sunlight. If you should have one, aPolariscope is an even better way to view the glass forstress. If it’s cracked, or abraded, even if it’s minor, theglass can fail under elevated pressure or temperatures.When washing, always take care not to bump glasstogether or against the wall of the sink. Also, always use asoft bristle brush or a brush with a plastic or wood handle.This will cut down on scratching. Never use HF or strongalkali soaps or acids to clean.When using glass labware, always make sure it’s borosil-icate glass or quartz. Some bottles used in lab work orsampling are made of soda lime or soft glass, and thesedo not have the temperature, pressure or autoclavingcapability of standard borosilicate or quartz labware.Autoclaving of glass: always make sure of the materialsyou are working with. Most lab glass is 32 to 33 expansionborosilicate glass. Standard borosilicate glass isautoclavable. One cautionary measure is to always let theautoclave and glass cool down slowly. Most failures aredue to two things: glassware that has a scratch orabrasion and can fail when autoclaved, or a very rapidcool-down or return to atmospheric pressure. That willexceed the differential pressure or temperature limits.

DEPYROGENATION AND ASHING OR EXTREMEHEAT CLEANING OF LAB GLASSWARE Any abrasions, micro-cracks or star cracks will weaken the glass and degrade performance. Any of these issueswill certainly cause the glass to fail when using hightemperature ovens. “Ashing” glass and mechanical ovensor furnaces that run over 500°C for long periods of timewill cause the glass to weaken and in some cases evenfail. It will certainly shorten the lifespan of your glassware.

BOROSILICATE GLASS TEMPERATURESStandard Use: Up to 240°CMaximum Use: For short intervals up to 450°C

CLEANING LAB GLASSWAREINTRODUCTIONLaboratory procedures require exact methods and shouldinclude good glassware cleaning to ensure excellent labresults. In all instances, labware should be physicallyclean, including both chemical residue free and greasefree and in many cases, it should even be sterile. All ClassA glassware used in precise measuring of liquids shouldhave fully wettable surfaces. A good test is to use distilledwater and see if the water wets all the inner surfacesequally. Grease or residues will not only contaminate thereaction and test results, but will also alter themeasurement of liquids.Good cleaning practices should also be accompanied bygood inspection of the glass surfaces for chips, cracks orabrasions which cause mechanical failure.CLEANINGAlways wash glass labware immediately after use. If athorough cleaning is not immediately possible, alwaysallow the glassware to soak. If not cleaned immediately,some residues may be impossible to remove later.Most new glass is slightly alkaline and should be washedupon receipt and generally can be soaked in a 1% HCl orHN03 solution before washing and a DI rinse.Never soak for long periods in strong alkaline solutions, asthis will damage the glass.Always follow up a soap or acid wash with a good DI water rinse.Always use soft brushes with a wooden or soft plastichandle to avoid abrasion. Do not use wire brushes orbrushes with a wire core as this can abrade the glass.GLASS CLEANERSAlconox® is the best cleaner to use, as it is not abrasive, in fact, Alconox offers a full line of detergents for soaking,hand washing, and automatic dishwashers. A detergent,such as a non-abrasive dishwasher soap will also workwell. Always use soft brushes. Always rinse glass well anddo a final DI rinse. If you need to do an acid wash, alwaysrinse the soap off the glass completely, where it maycause a reaction or leave a film on the glass. There aremany lab detergents available commercially such asMallinckrodt’s Klean-AR and CHEM-SOLV® Texwipe® and EM Science are good cleaning detergents.CHROMIC ACID OR CHROMERGE®

Chromic acid/Chromerge is a great cleaner, and will alsoremove organic residues. Use gloves and a well-ventilatedarea when using chromic acid, as it is a carcinogen andvery corrosive. Make sure metal clamps and/or flanges are


removed. It is best to fill the vessel or soak the item in thesolution for a short time in a plastic tub so that you cancontain the wash material, then rinse immediately, severaltimes before proceeding to a detergent wash. Make surethe residual chromic acid is diluted after use and disposedof properly according to your local and/or companyregulations.Occasionally, stronger acid washes are necessary forcertain types of precipitates or residues. It is best to keepthese very dilute and they should be used in an area where there is good ventilation. Make sure you contain theresidual acid and dissolved material for proper disposal.This method should only be used when absolutelynecessary. Disposal of seriously stained-glass may be aless troublesome and less expensive course of action thanusing strong acid washes. Be aware that through manycleanings of this type, the markings and graduations,although etched or burned into the glass will start to fade.REMOVAL OF GREASEGrease is best removed by boiling the glass in a weaksolution of sodium carbonate. Acetone or any other organicsolvent can also be used too, followed by several tap waterand DI water rinses.OTHER STAINSFor permanganate stains, use an equal mixture of 3%sulfuric acid and 3% hydrogen peroxide.For iron stains, use a solution containing one part HCl and one part water.For bacteriological contamination, glassware should besoaked in a disinfectant solution, steam autoclaved, andthen followed by a suitable wash and DI rinse.Caution: Make sure you refer to MSDS sheets for thecleaning solutions and the materials that were in theglassware to ensure that there won’t be any adversereactions from the combination of materials.ULTRASONIC CLEANERSUltrasonics is a good method of cleaning glassware.Ultrasonic cleaners that are heated will be the best typeand generally combined with a mild detergent, they willclean most residues off glassware. We typically clean allglass in our factory both during and after the fabricationprocess in heated ultrasonic cleaners.RINSINGGlassware should always have a water rinse after anycleaning procedure, followed by a DI rinse. It is best to givesmaller pieces, such as test tubes a soaking rinse followedby a DI soaking rinse. Glass pipets are best soaked in asuitable pipet washer and washed and given both a waterrinse and a DI soaking rinse. Pipets should be inserted incleaners with the tip down.DRYINGOven drying at 100°C is best for all glassware. If this is notconvenient, rack drying will work.

STEAM AUTOCLAVING OR STERILIZINGProper protocol for steam autoclaving borosilicateglassware is 15 to 20 minutes at 100-160°C. Always leaveclosures off or loose during autoclaving. Please refer toUSP or EP autoclave protocols.

INSPECTION AFTER CLEANINGAlways inspect all glassware before steam autoclaving forcracks, chips or damage. If it is already damaged, theautoclaving procedure will cause the glassware to break.Remember, all glass labware is generally borosilicateglass. The suggestions herein referred to borosilicateglass labware only. Bottles are generally NOT borosilicateglass and are made from soda lime or soft glass. Standardsample bottles do not have the temperature range orautoclave range of borosilicate glass. Please refer to themanufacturers’ cleaning procedures for those containers.Do not mix soda lime glass bottles and borosilicatelabware in the same washers or heat dryers andespecially not during autoclaving procedures.

STANDARD TAPER, GROUND JOINT GLASSGround joints are marked as S over T and stand forASTM, or ISO or DIN standard taper ground joints. Innerand Outer joints are matched by numbers. All joints hereinare referred to as full length joints. Some are referred to asAmerican joints. Euro joints or mid and short length jointsare also available from GLS.Ts is the symbol used to designate standard taper inter-changeable joints, stoppers, and stopcocks complying withrequirements of ASTM E675 for stopcocks, stoppers, andreagent bottle necks in E 676 interchangeable joints. Allmating parts are finished to a 1:10 taper.The size of a particular piece appears after the appropriatesymbol. Due primarily to the greater variety of apparatus-equipped standard taper fittings, a number of differenttypes of identifications are used, as follows:

HEADING APPARATUS AND BOTTLES1. For joints, a two part number, as Ts 24/40, with 24 being

the approximate diameter in millimeters at the large end of the taper, and the 40 is the actual length of taper, also in millimeters.

2. For bottles, a single number, such as standard taper 19,with 19 being the approximate diameter in millimeters ofthe opening at the top of the neck.

3. For glass stopcocks, a single number, such as standardtaper 2, with 2 being the approximate diameter in millimeters of the bore or bores through the plug.

4. For volumetric and Erlenmeyer flasks, graduatedcylinders, etc. a single number such as standard taper 19, with 19 being the approximate diameter in millimeters at the top of the neck. However, there are differences in dimensions between the bottle and flask stoppers, see the individual listings in this catalog.

Dear Customer,

We at Global Laboratory Solutions, GLS-USA, strive to provide our customers with

high-quality laboratory solutions mainly in the area of scientific laboratory glassware

and equipment. With over 30 years in this field, GLS-USA along with our partners

worldwide, have been manufacturing all types of laboratory glassware as well as

glass pilot plants for process and laboratory equipment. We have established a plant

and warehouse in North America located in New Jersey to service the US and

Canadian lab markets and scientists.

GLS’s range of glass products include a full range of glass components such as

beakers, flasks, vials, bottles, volumetric ware as well as various specialty glass

and apparatus for filtration, distillation, extraction, and reflux processes. The glass

components are manufactured generally to ASTM E438, Type I standards for 32-33

coefficient of expansion, borosilicate glass, known for its low thermal expansion,

excellent shock resistance, and chemical durability.

At GLS, we provide the widest range of glassware and our capabilities extend far

beyond that to the lab equipment market including components such as temperature

controllers, rotary evaporators, and stirring and mixing equipment.

GLS provides products to the Clinical, Industrial, and Academic markets including

schools, universities, research labs, petroleum companies, pharmaceutical,
