Millipore MilliWrap™ membrane sealing wrap film is the ideal replacement for metal caps, Parafilm*, cotton plugs and lids on all types of laboratory flasks, dishes, bottles and containers. These disposable membrane filtering sheets are composed of hydrophobic PTFE (polytetrafluoroethylene) and are treated with an antitoxic acrylic adhesive. Apply as a clean barrier that allows samples to vent while preventing contamination from condensation and airborne particles such as mold, spores and dust.
MilliWrap™ membrane sealing wrap is ideal for cell culture, botanical studies, media preparation, nitrogen studies and parasitology. Also useful in laboratory experiments where the expansion of air due to boiling or a chemical reaction can cause the container to explode if not ventilated. Milliwrap™ has a 0.45µm pore size and is 0.2mm thick. PTFE membrane film is chemically inert to most aggressive lab reagents, chemicals and solvents.
Parafilm M® lab wrapping film is a semi-transparent sealer which sticks instantly to itself and is ideal for sealing culture tubes, flasks, petri dishes and virtually any laboratory vessel or instrument. Parafilm M provides protection to your lab samples from outside air, gases, alcohols, most acids and lightly concentrated alkalies.
Economical and disposable covers provide dust-free storage of clean labware. Foil glassware and flask covers are pre-formed to quickly cover a wide variety of labware using only one hand. Ideal for use in centralized washing areas where cleaned labware needs to be transported back to the lab while remaining clean and contaminant-free. Cover-ALLS™ are autoclavable at 121°C (250°F) and are perfect for providing a temporary, sterile boundary for autoclave sterilization of labware.
Bel-Art Scienceware Super-Polyfoil™ Autoclaving Wrap Foil Sheets are ideal for covering flasks and lab containers piror to autoclaving, incubating or storing cell culture solutions and reagent chemical solutions. Polyester-backed foil sheets are the ideal alternative to plain aluminum foil which oxidizes and kinks easily. A unique polyester layer is adhered to the aluminum foil sheet which provides, providing sterile protection and a chemical-resistant barrier. The film backing also prevents pinholes and is resistant to most solvents and caustic reagent chemicals. Foil sheets fold easily and flatten neatly without. Materials are compliant with FDA regulations concerned with direct food contact.
