The patent pending EZ-Clamp™ Test Tube Rack Clamp was designed with the researcher in mind. Tired of wasting time with the same old screw down, hard to load flask clamps with over stretched springs and stripped screws? EZ-Clamps do not screw down or over stretch. Instead, they powerfully adhere magnetically to shaker platforms allowing for single-handed (tool free!) attachment and reconfiguration. One-size clamp fits all LabStrong test tube half racks, so stop searching and do more researching. *Test Tube Half Racks Sold Separately.

Features:

• Magnetically adheres to platform, requiring absolutely no tools!
• Finger-tightening knobs allow for variable tilting of racks
• The tilt adjustable clamps save valuable space in your lab
