Laboratory Glassware Suppliers in India

A workable starting set per bench: beakers in 50, 100, 250, 500 and 1000 mL; conical flasks in 100, 250 and 500 mL; measuring cylinders in 10, 50, 100 and 500 mL; volumetric flasks in 25, 50, 100, 250 and 1000 mL; a 25 mL and 50 mL burette; and GL45 reagent bottles in 250, 500 and 1000 mL. Add Petri dishes and culture tubes if you run microbiology. Share your method list and we will size the order against it.

Buy Class A only where the number is reported or the method is validated — pharmaceutical QC, NABL scope, referee analysis. Buy Class B for preparation, teaching and any step where the volume is not the measurement. A laboratory that buys Class A across the board is spending two to three times more than the method requires on most of its glassware.

Glass for heating, solvents, precision measurement and anything entering a validated method. Plastic for hydrofluoric acid, strong alkali, field work, teaching laboratories and any bench where breakage is the dominant cost. Most laboratories run both and choose per task rather than standardising on one.

Glassware breaks at a predictable rate — track your replacement consumption for a quarter and order against it. Bulk pricing improves materially at case quantities, and a rate contract with scheduled delivery gives you the bulk price without holding the stock. Tell us your annual consumption and we will structure it.

Inspect for chips at the rim and star cracks at the base before the consignment is accepted — both are breakage waiting to happen under heat. Confirm the graduation printing is fired-on enamel, not screen print. For Class A items, confirm the certificate is present if you specified one.

Start with the test method, then match the item to the handling step. Water and environmental laboratories commonly require BOD bottles 300ml where specified by the method, measuring cylinders for graduated volumes, reagent bottles for compatible sample or reagent storage, funnels and filtration assemblies for preparation. Send ScientificEdge the method, required capacity and any documentation requirement so we can confirm a suitable current product specification before quotation.

Yes. For pharmaceutical QC and CRO workflows, we help identify Class A and certificate options; for microbiology, sterility and autoclavability; for chemical and petrochemical labs, material compatibility and closure type; and for teaching, class-size kits and breakage economics. Share the method, chemistry, capacity, accuracy class and procurement format so ScientificEdge can recommend the relevant product category rather than a generic catalogue list.

For heating and general solution preparation, a borosilicate glass beaker 1000ml is a common bench size. Specify a low form beaker with spout for general mixing and pouring, or a tall form beaker where the taller profile suits the method. A conical flask 250ml is a common titration and culture size; use a flat bottom flask only where stable upright heating or storage is required. For a reported concentration, choose a volumetric flask Class A with calibration certificate when the manufacturer makes that documentation available for the selected item.

Specify the closure and light protection along with the volume. A reagent bottle GL45 uses the common GL45 thread; an amber reagent bottle wide mouth is suitable when easy filling and protection of light-sensitive material are both needed. For high-volume storage, ask for a square lab storage bottle GL80. BOD bottles 300ml are selected for the relevant water-testing method, while an aspirator bottle with stopcock is used for controlled dispensing of compatible liquids. ScientificEdge confirms the current manufacturer specification, cap compatibility and availability before quotation.

For regulated or validated work, request NABL certified volumetric glassware only when the supplied item is accompanied by the relevant certificate from its manufacturer or calibration provider. A measuring cylinder Class A is appropriate for more accurate graduated-volume work; a glass burette with PTFE stopcock is commonly selected for titration where chemical compatibility and smooth flow control are required. Tell ScientificEdge whether you need Class A, the calibration standard, certificate type and the method so we can confirm the exact documentation before you order.

ScientificEdge is an independent supplier, not a manufacturer. We source through traceable channels, match the requested specification before quotation, preserve available batch details from receipt to dispatch, and provide manufacturer documentation where issued for the selected product. This helps procurement and QA teams verify material, class, capacity, certificate availability and brand before goods are accepted.

Borosilicate 3.3 is a glass with a low coefficient of thermal expansion, around 3.3 × 10⁻⁶ K⁻¹, manufactured to ISO 3585. That low expansion is what lets it survive rapid temperature change without cracking. It also resists most acids and solvents. It is the correct default for any laboratory glassware that will be heated, autoclaved or used with strong reagents.

Class A carries approximately half the permissible volumetric error of Class B and is available with a batch or individual calibration certificate. Class B costs less and is entirely adequate for preparation, teaching and any step where the volume is not the reported measurement. Use Class A where the number appears in a report or the method is validated.

TC or IN means the vessel holds the stated volume when filled to the mark — this is how volumetric flasks are calibrated. TD or EX means it delivers the stated volume when emptied, allowing for the film of liquid left behind — this is how pipettes and measuring cylinders are calibrated. Using a TC item as if it were TD introduces a systematic error.

Not for anything you will report. Beaker graduations are indicative and typically carry an error around 5%. Use a measuring cylinder for moderate accuracy and a Class A volumetric flask or bulb pipette where accuracy matters.

Borosilicate 3.3 glassware and polypropylene labware autoclave at 121 °C. Loosen all caps and closures first. Polystyrene deforms and should be treated as single-use, and polycarbonate degrades over repeated cycles. Always cool gradually rather than removing into cold air.

Polypropylene or PTFE. Hydrofluoric acid attacks glass, so no borosilicate item is suitable regardless of grade. PTFE offers the widest chemical resistance; PP is the economical choice for routine HF handling.

Almost always thermal shock on soda-lime glass, or an existing chip or star crack concentrating stress in borosilicate. Confirm the item is borosilicate 3.3, inspect the rim and base before heating, and avoid placing hot glass on a cold surface.

ScientificEdge is an independent supplier and distributor — we do not manufacture these products. We source through traceable channels, preserve batch details from receipt to despatch, and supply manufacturer documentation with the goods, so a lot can be traced back if it is ever questioned during an audit.

Class A certificates and conformance documentation are available on request wherever the manufacturer issues them for that item. Tell us at the enquiry stage if your quality system requires a certificate with the consignment and we will confirm what is available before you raise the order.

Yes. Delhi NCR is our home market — Delhi, Noida, Greater Noida, Ghaziabad, Faridabad and Gurgaon — with same-day dispatch on stocked lines. We also supply laboratories across Uttar Pradesh, Haryana, Punjab, Rajasthan, Maharashtra, Gujarat, Karnataka, Tamil Nadu, Telangana and West Bengal.

Yes. Glassware and plasticware are high-consumption items and are priced materially better at case quantities. Share your monthly or annual consumption and we will structure a rate contract with scheduled deliveries, so you get bulk pricing without holding the stock.

Yes. We support government and institutional procurement including GeM, CPPP and state e-procurement portals, and we have experience with the documentation, specification-matching and compliance formats these processes require.

Yes. We supply teaching laboratories with departmental kits sized to practical class strength, typically weighting Class B glassware and polypropylene where breakage economics favour it, and Class A only where a method genuinely requires it.

Yes. We issue GST-compliant invoices and supply the documentation institutional and government buyers require, including performance specifications and compliance statements.

Commonly stocked lines typically dispatch within a few working days, and same-day in Delhi NCR. Specific sizes, joint configurations and Class A certified items may be indent with a longer lead time. We confirm the actual timeline on your quotation rather than promising a generic number.

Yes. Share the current make, catalogue number or drawing and we will identify the direct equivalent, plus a technically better alternative if one exists at similar cost. We will also tell you clearly when the upgrade is not worth the money.

Standard taper joints including 14/23, 19/26, 24/29, 29/32 and 34/35. Confirm the joint on your existing condenser, distillation head or flask before ordering — a mismatched joint is the most common reason a consignment has to be exchanged.

Yes. ScientificEdge supplies laboratory chemicals, filtration products, syringe filters, pipettes and tips, water purification systems, life science consumables and general laboratory equipment, which lets laboratories consolidate purchasing with a single accountable supplier.
