The 5.0 ml ClikLok™ and MacrewTube™ microcentrifuge tubes have been designed for the simple and safe processing of medium-sized sample volumes.

• Made of high-quality, transparent polypropylene without use of slip agents, plasticizers, mold release agents, and biocide substances
• Centrifuge up to 25000 ×g
• RNase, DNase, Pyrogen, and DNA-free
• Operating temperature range from –196 to 121 °C
• Autoclavable
• Use the color-coded CapInsert™ for easy identification

Designed for samples larger than 2.0 ml. The 16mm tube diameter is identical to the diameter of standard 15 ml tubes, ensuring further compatibility with centrifuge rotors. Both the ClikLok™ and MacrewTube™ are designed with a smooth bottom with no sharp points to prevent hurting user fingers. The slim design fits high capacity rotors. Tubes are graduated every 0.5 ml.

The ClikLok™ snap cap tube is available with a flat top or with a CapInsert™ cavity for color-coding purposes. The cap will partially open when the internal pressure approaches an unsafe level in a controlled manner, releasing excess pressure but preventing any splashing of contents. In applications over 80 °C, the CapLock™ Clips are recommended.

The screw cap MacrewTube™ is available sterile and with a choice of two caps, either a regular lip seal cap or a tethered cap. Both models have the CapInsert™ cavity for color-coding purposes.
