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. A pack suits school, college and university chemistry and biology practicals, from simple reactions to salt analysis. Sold as school chemistry lab equipment in India, the packs leave Ambala through Science Lab Supplies for schools, research laboratories, tender contractors and distributors.

Specifications

Pack size, material and the other test tube details appear row by row below. In short, 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 are stated on the quotation for the tubes offered.

Applications and Experiments for Test Tubes

Test tubes are the basic vessel for qualitative work: a few millilitres of solution, a reagent added drop by drop, and the result read by eye. A pack of 100 can stock a class for reactions, identification tests and demonstrations across school and college science practicals.

• Class 10 science: reactions of acids, bases and salts and types of chemical reaction, mixed with a Glass Stirring Rod.
• Class 11–12 chemistry: systematic salt analysis and tests for organic functional groups.
• School biology: food tests for starch, sugar and protein, warmed over a Bunsen Burner where heating is allowed.
• 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 on the same document.

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. Give the number of packs on the contact page, drop the tubes into the enquiry cart beside racks and holders, or see the lab tender page when a school buys by tender.

Frequently Asked Questions

How many test tubes are in a pack?
Each pack contains 100 test tubes. Several packs can be quoted together to cover a term of practical classes, and the quotation states the price and packing for the exact number of packs.

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 same order and quotation.

Who supplies these Test Tubes?
Packs are priced and dispatched by Science Lab Supplies of Ambala, India. Schools, colleges, distributors and tender contractors can take them in bulk together with the rest of their glassware list on a single quotation.
