Glass Test Tubes (100 Pieces)

The glass test tubes are laboratory vessels used for holding, mixing, observing and carrying out small-scale procedures with compatible substances. Supplied as a pack of 100 pieces, they are intended for school, college, chemistry and general laboratory environments that require multiple test tubes for routine practical work.

Product Description

The STEMAids Glass Test Tubes (100 Pieces) provide laboratories and educational institutions with a bulk set of individual glass tubes for general experimental and sample-handling tasks. Their transparent construction allows users to observe liquids, precipitates, colour changes and other visible reactions during practical work.

The confirmed pack quantity is 100 pieces. The exact glass composition, tube dimensions, wall thickness, rim design and temperature resistance are and should be checked against the current STEMAids manufacturing specification before publication or procurement. Related items can be found in the STEMAids lab glassware range.

How to Use the Glass Test Tubes

1. Inspect each test tube for cracks, chips or damaged edges before use.
2. Select a clean tube appropriate for the planned laboratory procedure.
3. Place the test tube in a suitable rack when filling, storing or arranging samples.
4. Add only compatible substances using suitable laboratory transfer equipment.
5. Mix contents only by the method specified in the applicable experiment or laboratory procedure.
6. After use, empty and clean the tube according to the substances handled.
7. Allow reusable tubes to dry completely before storage.

Safety note: Wear appropriate laboratory PPE. Never use cracked or chipped glassware. Do not directly heat these tubes unless their glass type and thermal suitability have been confirmed for that procedure.

Care & Maintenance

• Wash reusable tubes using a cleaning method compatible with the substances previously contained.
• Use an appropriate test-tube brush where mechanical cleaning is required.
• Allow the tubes to dry fully and store them securely in a suitable rack or protected container.
• Discard damaged tubes according to your laboratory’s broken-glass procedure.
