Glass Test Tubes (100 Pieces)

Quick Answer

This listing supplies plain glass test tubes in a pack of 100 pieces, giving a laboratory, school, or training program enough tubes to fully stock a class set or run high-volume sample handling without constantly washing and reusing the same small batch.

Description

Test tubes are one of the most frequently used pieces of glassware in any laboratory or classroom, serving as small, open-topped vessels for holding, heating, mixing, or observing liquid and solid samples. Supplying them as a pack of 100 pieces suits settings where many students or technicians need their own tube at the same time, or where a lab runs a large number of small-scale reactions, titrations, or sample checks in a single session.

Having a full set of 100 on hand also reduces the pressure to immediately wash and reuse tubes between classes or batches, which is useful in busy teaching labs and in quality-control settings where sample turnover is high. Each tube in the set is a standard open-top laboratory tube suited to general-purpose mixing, heating over a flame, and simple qualitative tests.

Specifications

Applications

• Running qualitative chemical tests and colour-change reactions
• Heating small liquid samples directly over a burner flame (borosilicate-rated tubes only)
• Holding and organising multiple samples during a teaching session or practical class
• General-purpose mixing and observation in school and college laboratories

Care & Handling

• Inspect each tube for chips or cracks before use, especially around the rim, and retire any damaged tube
• Use a test tube holder or rack when heating, never hold a hot tube directly in bare hands
• Clean with a test tube brush and appropriate detergent, rinsing thoroughly before reuse
• Store upright in a test tube rack or stand to prevent tubes rolling off the bench and breaking
• Allow tubes to cool gradually after heating rather than plunging them into cold water

Frequently Asked Questions

How many test tubes come in this pack?

This pack contains 100 individual glass test tubes, enough to equip a full classroom set or keep a busy laboratory supplied without needing to wash and reuse the same small number of tubes between sessions.

Can these test tubes be heated directly over a flame?

Test tubes made from borosilicate glass can generally be heated directly over a low flame with care, always pointing the open end away from yourself and others; check the specific glass type at enquiry if direct flame heating is central to your use.

What is the best way to store 100 test tubes safely?

Store them upright in a test tube rack or stand rather than loose in a drawer or box, which keeps them organised, reduces the chance of chipped rims, and makes it easy to see which tubes are clean and ready for use.

Are these test tubes suitable for a school laboratory?

Yes, a pack of 100 plain glass test tubes is a common choice for school and college laboratories that need to equip multiple students or benches at once for general mixing, heating, and qualitative testing exercises.

How should I clean glass test tubes between uses?

Clean each tube with a test tube brush and a suitable laboratory detergent, rinse thoroughly with water, and allow it to air dry or dry in a rack before the next use to avoid contaminating the following sample.

Can I order additional packs of test tubes in bulk?

Yes, LabEquip can supply glass test tubes in bulk beyond a single 100-piece pack for larger institutional or laboratory requirements; contact us with your total quantity and we will assist.
