Now with one hand, you can easily unscrew just about any type of microcentrifuge tube with a screw-on closure

Made of highly resistant acetal polymer, it will not shatter or stain in contact with most laboratory chemicals. No coating to worry about, so it will not chip, peel or rust in a water bath.

Thanks to an innovative locking system, the Simport self-standing Micrewtubes® will securely lock in each well of the base tier and will not turn. All models of microtubes made by various manufacturers will lock in the upper tier, thanks to a series of teeth grasping the collar of the microtube. Convenient handles on each side of the rack will ensure a safe grip when carrying it around. Interlocking feet allow safe stacking.
