Brass Laboratory Test Tube Holder

The Brass Laboratory Test Tube Holder is a laboratory hand tool used for gripping and handling compatible test tubes without direct hand contact. Made with brass construction, it is intended for supervised chemistry, biology and educational laboratory procedures where test tubes must be held, repositioned or supported during practical work.

Product Description

The STEMAids Brass Laboratory Test Tube Holder provides a mechanical grip for holding compatible test tubes during laboratory handling. It is especially useful when direct hand contact with the tube is inconvenient or inappropriate during experiments, demonstrations or selected heating procedures.

The confirmed construction material is brass. The exact brass grade, overall length, jaw design, spring or gripping mechanism, handle configuration and maximum working temperature are .

How to Use the Brass Laboratory Test Tube Holder

1. Inspect the holder for deformation, loose components, corrosion or damaged gripping surfaces.
2. Select a test tube that fits securely within the holder’s verified gripping range.
3. Open or position the holder according to its gripping mechanism.
4. Grip the test tube securely without applying excessive force to the glass.
5. Keep the tube opening directed away from yourself and other people during laboratory procedures.
6. Move or support the test tube slowly and maintain a secure grip throughout the operation.
7. Place the tube safely in a test-tube rack or other suitable support before releasing it.

Safety note: A test tube holder reduces direct contact but does not remove heat or chemical hazards. Wear appropriate PPE. When heating a test tube, keep its open end pointed away from people and never use damaged glassware or an unsuitable holder.

Care & Maintenance

• Allow the holder to cool completely before cleaning if it has been used near a heat source.
• Remove chemical residue with a cleaning method compatible with brass.
• Inspect the jaws and operating mechanism regularly for wear or loss of grip.
• Store clean and dry to reduce corrosion and mechanical damage.
