Porvair Sciences Ultraseal™ Gas Perm Seal 2 - Lab Sheet SF13078LS

Ultraseal™ Gas Perm Seal 2 - Lab Sheet is a heat-sealable, gas-permeable lab sealing sheet designed to provide a porous barrier against solid contamination while allowing gas exchange. It is intended for short-term incubations and applications such as cell culture, agriculture and seed storage, and insect storage, providing an inert surface with no adhesive to interfere with well contents. The product is supplied as 125 x 78 mm lab sheets in a pack of 100 (product code SF13078LS).

Key Features:

• Format: Lab sheets, size 125 x 78 mm
• Material: 60 gsm paper with grid lacquer coating (porous, gas permeable)
• Quantity: 100 sheets (SF13078LS)
• Temperature range / seal integrity: -20°C to 80°C; recommended sealing 175°C for 2 seconds
• Features: Peelable and pierceable; moderate solvent resistance
