PetriSeal™ stretches and conforms to form a tight seal and is temperature resistant, waterproof and chemically resistant. It resists abrasion and puncture and blocks vapor loss while reducing the rate of gas exchange. Use PetriSeal™ with microtiter plates, Petri dishes and culture plates to prevent to entry of contaminants. The seal remains flexible down to -30°C and can withstand continuous exposure from -40°C to +77°C (with intermittent exposure up to 100°C). Tests have shown that PetriSeal™ leaves no adhesive residue even after two years.
