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
