How to Use the Test Tube Holder Rack

1. Place the rack on a stable, level laboratory bench.
2. Check that the rack is clean, dry and free from cracks, deformation or damaged supports.
3. Select test tubes that fit the verified opening diameter and rack height.
4. Insert each tube vertically into an individual holding position.
5. Arrange samples according to the laboratory procedure and use clear labels where required.
6. Avoid overloading the rack or using tubes that do not fit securely.
7. Remove tubes carefully and clean the rack after the laboratory session.

Safety note: Do not place tubes in openings that are too small or unstable for their diameter. Keep the rack away from bench edges, and use appropriate PPE when tubes contain chemicals, biological samples or hot materials.

Care & Maintenance

• Clean spills promptly using a method compatible with the confirmed rack material.
• Allow the rack to dry fully before storage or reuse.
• Inspect openings and supports regularly for cracking, corrosion, warping or other damage.
• Use autoclaving or chemical disinfection only when the rack material is confirmed as compatible.
