These Microcentrifuge Tubes feature a snap closure for a leak-tight seal. They have a pierceable cap for sample removal, graduated marks for volume estimation and frosted writing area for labeling. They are autoclavable to 120°C, freezable to -80°C and can withstand up 17,000 x g.
Certified RNase and DNase free microcentrifuge tubes are tested by an independent lab and certified to be free of nucleases. Pre-sterilized microcentrifuge tubes are ideal for labs that don't have access to an autoclave. They are an economical way to do experiments with a small number of samples. They are individually wrapped to assure sterility.
Low adhesion microcentrifuge tubes have specially blended resins that eliminate the use of lubricants which may be harmful to samples. Liquid retention is minimized and optimum yield is ensured. They are manufactured and packaged to ensure tubes are DNA-, DNase- and RNase-free.
