Heavy-Duty Test Tube Rack with Silicone Grips | 18mm, 50-Well

Upgrade your laboratory organization with our 50-Well Test Tube Rack, specifically designed for high-stability sample handling. This rack features an innovative silicone grip system in each hole, which securely holds tubes with a diameter of 17mm to 18mm.

The unique silicone “fingers” or gaskets provide a firm, centralized hold, allowing you to invert the rack without the tubes falling out—ideal for decanting or rapid processing. Crafted from high-density polypropylene or ABS, this rack is built to survive rigorous daily use while resisting acids, alkalis, and common lab chemicals.

Key Features

• Silicone Grip Technology: Internal gaskets firmly hold tubes in place, providing better stability and protecting glass tubes from rattling or breaking.

• High Capacity: Accommodates up to 50 tubes in a clean 5 x 10 grid layout.

• Universal Fit: Perfect for 18mm diameter test tubes, centrifuge tubes, and blood collection tubes.
