Description

Improve sample recovery by significantly reducing surface binding with Thermo Scientific™ Snap Cap Low Retention Microcentrifuge Tubes. Viscous liquids and costly reagents retained in a microcentrifuge tube effect assay accuracy and precision. With no additives or coatings, these tubes — available in 0.6mL, 1.5mL and 2.0mL sizes — offer maximum sample recovery by significantly reducing surface binding.

• The duckbill cap reduces the pressure required to open the tube with a wider contact surface, yet ensures the cap will remain closed during centrifugation
• Low retention properties are not achieved by a coating or plastic-embedding processes, ensuring that samples will not be contaminated from these additives
• Tubes will remain closed during centrifugation yet open easily with one hand as needed
• Tubes are available in amber to protect your light-sensitive samples
• Graduation marks on the microcentrifuge tube allow for effective sample reference

Color/Packaging  Options

• A variety of packaging options are available to help with contamination control in the lab
• For stringent sterility requirements, individually wrapped sterile tubes are available
• Color options, in addition to natural and amber, are red, blue, green, yellow and violet and a mixed color packaging

Highest Quality

• Manufactured from virgin polypropylene, these microcentrifuge tubes ensure sample integrity during boiling, freezing and centrifugation
• Sterile product is certified free of RNase, DNase, DNA, ATP, bioburden and endotoxins
• Nonsterile product is certified free of RNase, DNase, DNA and pyrogens

Recommended for:

Daily laboratory usage including centrifugation and short-term sample storage
