Cole-Parmer® Microcentrifuge Tubes with BackSpring Cap, Polypropylene, 1.5 mL

Easy to open microcentrifuge tubes with backspring flip cap eliminates sore thumbs

Reduce the stress on your hand due to repeatedly opening and closing microcentrifuge tubes. This unique 1.5 mL tube opens by pushing a tab at the back of the cap allowing for easy, one-handed operation. Useful for processing and storage of small volume samples, reagents and extracts, they have a MAX RCF (maximum relative centrifugal force) of 25,000 x g. The smooth, transparent tube body has clear graduations from 0.1 to 1.5 mL in 0.25 mL increments, and a frosted marking area for easy tagging and identification.

These conical bottom microcentrifuge tubes are made of high-quality polymer polypropylene (PP), are strictly tested for leakage, and have excellent sealing performance. They withstand temperatures from -80 °C (-112 °F) to 121 °C (250 °F), and are DNase/RNase free, nonpyrogenic, and conform to USP Class VI standards. Packaged in resealable bags of 500, they have a printed lot number for quality traceability.
