The plastic and glass surfaces of pipette tips and tubes including PCR tubes, microcentrifuge tubes, and conical tubes, are an easily overlooked source of ribonuclease (RNase) contamination. Thermo Fisher offers a range of RNase-free plastics including pipette tips, PCR tubes, microcentrifuge tubes, and conical tubes. Each lot of Invitrogen brand tips and tubes undergoes rigorous testing to ensure that they are nuclease-free (RNase- and DNase-free).

Basics of RNase control Working with RNA

RNase-free, nuclease-free tips and tubes

移液器枪头和试管(包括PCR管、 微量离心管和锥形管)极易成为被忽视的RNA核酸酶（RNA酶）的污染源。

我们可提供各种不含RNA酶的塑料移液器枪头、PCR管、微量离心管和锥形管。每个批次的Invitrogen™ Ambion™ 枪头和试管均已经过严格的检测，不含RNA酶。

RNase-free pipette tips

For safe transfer of samples and reagents, RNase-free pipette tips come in two different formats: without a barrier/filter and with a barrier/filter (also known as barrier tips or filter tips). Both formats have the following features:

  • E-beam sterilized—nuclease-free and RNase-free
  • Autoclave-safe
  • Compatible with a broad range of pipettors

RNase-free PCR tubes

RNase-free PCR tubes are available in different varieties. RNase-free PCR tubes offer thinner walls to allow for better sample temperature regulation, as well as frosted surfaces for easy labeling. Other options include domed or flat caps, as well as 0.2 mL and 0.5 mL formats. Thermo Fisher RNase-free PCR tubes have the following features:

  • Certified nuclease-free and RNase-free
  • Allow uniform contact with the thermal cycler temperature block
  • Autoclave-safe

RNase-free microcentrifuge tubes

RNase-free microcentrifuge tubes are available in three different sizes (0.5 mL, 1.5 mL, and 2.0 mL) and have marked gradations for convenience. Our microcentrifuge tubes are lot tested for contaminants, such as nucleases including RNases and DNases. All our RNase-free microcentrifuge tubes have the following features:

  • Certified nuclease-free and RNase-free
  • Non-stick, low-binding surface
  • Positive-seal design that prevents caps from opening in boiling water baths
  • Autoclave-safe

RNase-free conical tubes for safe storage of samples and reagents from RNases

RNase-free conical tubes are available in two different sizes (15 mL and 50 mL) and have printed writing space and volume marks for convenience. Our RNase-free conical tubes have the following features:

  • Certified nuclease-free and RNase-free tubes come racked and are pre-assembled with green screw tops
  • Tubes come racked and are pre-assembled with green screw tops
  • Autoclave-safe
