Test Tubes

Product Code : SCL-LG-11993

Test Tubes (SKU SCL-LG-11993) are narrow glass laboratory tubes, sold in packs of 100, for holding, mixing, heating where suitable and observing small quantities of substances. Schools, colleges and university chemistry and biology laboratories go through them in every practical period, from simple reactions to salt analysis. Science Lab Supplies supplies these packs from Ambala, India to schools, colleges, research laboratories, tender contractors and distributors, as school chemistry lab equipment in India.

Specifications

Each pack holds 100 transparent glass tubes, so colour changes, precipitates, dissolution and liquid levels are easy to see. Capacity, dimensions, glass grade, rim and suitability for direct heating vary between tube types and are stated on the quotation for the tubes offered.

Applications and Experiments for Test Tubes

Test tubes are the everyday vessel for qualitative work: a few millilitres of solution, a reagent added drop by drop, and the result read by eye. Buying by the hundred keeps a class stocked for reactions, identification tests and demonstrations across school and college science.

• Class 10 science: reactions of acids, bases and salts and types of chemical reaction.
• Class 11–12 chemistry: systematic salt analysis and tests for organic functional groups.
• School biology: food tests for starch, sugar and protein.
• B.Sc. inorganic chemistry: qualitative analysis of cations and anions.

Never heat a closed tube; when heating is allowed, use a holder and point the open end away from everyone.

Standard Scope of Supply

One pack contains 100 test tubes. Test tube racks, holders, stoppers, cleaning brushes and reagents are not included. If you want racks or holders for each student group, name them in your enquiry and they can be quoted with the tubes.

Packing, MOQ and Lead Time

Quote requests can be for a single pack or for many packs to cover several laboratories for a term. Every quotation spells out packing, delivery time and price for the number of packs requested, and other chemistry lab equipment in India can sit on the same quote.

As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. Send your pack count through the contact page, or place the tubes in the enquiry cart with your other items; schools buying under a tender can refer to the lab tender page.

Frequently Asked Questions

How many test tubes are in a pack?
Each pack contains 100 test tubes. Laboratories usually order several packs at once to cover breakage across a term of practical classes.

Can these test tubes be heated directly?
Whether a tube can go into a flame depends on its glass type. Confirm heating suitability for the tubes on your quotation before direct heating, and never heat a stoppered tube.

Are racks or stoppers included?
No. The pack contains the tubes only. Racks, holders, stoppers and brushes are separate items that can be added to the order.

Who supplies these Test Tubes?
The packs are supplied by Science Lab Supplies from Ambala, India. Schools, colleges, distributors and tender contractors can order them in bulk together with the rest of their glassware list.

Related Everyday Lab Glassware

Test tube work needs a few companions on every bench: something to add reagents drop by drop, something to stir, a vessel for larger volumes, and tubes that can go into a centrifuge. These four items are commonly ordered alongside test tube packs.

• Glass Dropper Pipette 6 — adds reagents drop by drop.
• Glass Stirring Rod — mixes contents and transfers drops for testing.
• Borosilicate Beaker — for preparing larger volumes of solution.
• Glass Centrifuge Tube — when a precipitate must be separated by spinning.
