Seal-Rite® tubes protect your samples with a dependable precision sealing system that prevents evaporation, leakage, and accidental opening. The tubes are easy to open by hand but will stay closed during boiling, freezing, centrifugation, and exposure to phenol/chloroform mixtures. The tube thickness is optimized for clarity and strength.

Seal-Rite® tubes are pure 100% virgin polypropylene. No processing additives such as slip agents, biocides, or antistatic agents are used during production. Certified RNase, DNase, DNA free and non-pyrogenic.
