United Scientific™ Rotator Workstation Rack, Assorted, Pack of 4

20 Racks of 25 Polypropylene tubes with conical bottoms and 50ml capacity. Blue HDPE leak-proof screw caps included. Centrifuge tube and rack sets are a convenient solution for organizing and storing conical bottom tubes. Racks are made of expanded polystyrene (EPS) and include holes arranged in a zigzag format for easy dispensing. Tubes have an outer diameter of 29.2mm and are 114.3mm tall. Tubes and caps feature specially-designed flat threads for vacuum-type closure that is leak-free at a pressure of >700mm Hg. Highly smooth hydrophobic internal surfaces minimize wall effect. ...

MTC™ Bio's 25ml tube is the newest addition to our family of screw cap conical tubes. Closing the obvious gap between 15ml and 50ml tubes, they are ideal for any application that requires more than 15ml and less than 50ml, including midipreps, general sample prep, centrifugation, mixing and storage. Aside from the reduction in freight costs, storage space and plastic waste, the 33% reduced height and large diameter design (which is identical to 50ml tubes) allows for faster re-suspension of pellets and 100% recovery of small samples. Concerns about cross-contamination (a frequent ...
