Ideal sealing tape for petri dishes and micro-well plates. Tape stretches and conforms to ensure a tight seal. Designed to prevent water vapor loss, reduce rate of gas exchange and prevent entry of contaminants. Tape is easily removed from most surfaces without leaving a residue. Elastomeric plastic withstands continuous exposure from -40°C to 77°C (with intermittent exposure to 100°C). Resistant to most organic solvents. Ensures a tight seal Prevents vapor loss
