Protect your samples with Seal-Rite® microcentrifuge tubes. Seal-Rite tubes are 100% pure virgin polypropylene. No processing additives such as slip agents, biocides, or antistatic agents are used during production. Your samples remain protected from potential bioactive contaminants.
The Seal-Rite precision sealing system prevents evaporation, leakage, and accidental opening. Caps seal securely, yet are easy to open.
Broad, beveled cap rims provide more comfortable handling.
Long cap plugs with pronounced sealing rims resist deforming and provide more surface area for better sealing.
Extended sealing zones ensure good contact with the cap plugs for better resistance to pressure during boiling or storage.
