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 ...
