Frequently Asked Questions
Which width should I select for sealing standard flasks and beakers?
The 4 in. rolls suit most beakers, flasks, and bottle necks, while the 2 in. width fits tubes and small vessels. Choose the 20 in. × 50 ft roll for trays, large containers, or cutting custom sheets.
What is the difference between the dispenser-box and plain-roll options?
Dispenser-box SKUs (SRF-PRCD-series) include an integrated cutter for one-handed tear-off at the bench. Plain rolls offer the same film at a lower price when you already have a dispenser or prefer manual cutting.
Is the film sterile?
No. Seal-R-Film® is supplied non-sterile and is intended for sample protection, covering, and short-term storage rather than aseptic applications.
What temperature conditions does the film tolerate?
The flexible film is best suited to ambient and refrigerated storage. It is not intended for autoclaving or sustained high-heat exposure; remove before heating or sterilization steps.
