How to Use the Laboratory Sample Test Tubes

1. Inspect each test tube for cracks, chips, scratches, or contamination before use.
2. Select a clean tube suitable for the sample volume and laboratory method.
3. Add only the required quantity of compatible sample or reagent.
4. Hold the tube with a suitable test tube holder during heating or transfer.
5. Heat gently and evenly if the experiment permits heating.
6. Point the open end away from people during heating or reaction work.
7. Place used tubes in a rack, not loose on the bench.
8. Clean, rinse, dry, and inspect the tubes before storage or reuse.

Safety note: Use only under trained supervision. Do not heat sealed tubes, overfill tubes, use damaged glassware, or mix unknown chemicals without an approved laboratory procedure.

Care & Maintenance

• Wash test tubes promptly after use to prevent dried residue and staining.
• Use a suitable test tube brush without scratching the glass wall.
• Dry tubes fully before storage to reduce water marks and contamination.
• Discard any tube with cracks, chips, sharp edges, or heat-stress marks.
