Celltreat 15mL and 50mL Centrifuge Tubes are made of high-clarity polypropylene and have smooth, flat surface HDPE caps. Graduations are printed in a bold easy-to-read black and are accurate to ± 2%. A large white marking area provides excellent contrast for identification. Temperature use range is -80°C to 120°C. All are conical bottom except EF8896L, which is self-standing.

Choose from tubes with two types of caps:

Screw caps have smooth, flat surface HDPE plug-seal caps. An extended cap design facilitates one hand removal of caps and helps prevent contamination. Available with large white numbered caps (1-25), or with white marking spots to aid in identification

Flip-top caps have an ergonomic leak-free flip-top cap design that allows easy one-hand opening of caps without loss of cap.

Tubes are available in recyclable racks, bulk packaged in sterile re-sealable (zip closure) bags, or plastic racks. Plastic racks are made from polypropylene and autoclavable, reusable, recyclable, and available separately (see accessories).

Inner bags contain lot number information. Sterile tubes are manufactured in a Class 100,000 cleanroom environment and are gamma irradiation sterilized (10-6), RNase-free, DNase-free, DNA-free, and non-pyrogenic.

Plastic racks are available for 15 and 50 mL tubes. They are made from polypropylene and are autoclavable, reusable, and recyclable.
