Globe Scientific GTR-HD-15H 48 Position Horizontal Tube Rack Holder for 15mL Centrifuge Tubes - Lab Equipment for PCR, DNA Testing & Sample Storage

The GTR-HD Tube Rotator provides slow to vigorous mixing of your biological samples and solutions with advanced features you expect. Adjusting the speed and time are easily performed using the parameter adjustment knob on the front panel. A metal chassis and rotisserie-style tube holders provide a solid, robust design for years of worry free mixing. Swapping the included 50mL vertical holder is a breeze: lift the retention lever on the left, angle the main housing on the right and lift out - replacing would be the opposite process. Both vertical "end over end" mixing and horizontal "rolling" mixing tube holders are available for 1. 5 / 2. 0mL, 15mL & 50mL tubes.
