It has been specifically designed for pharmaceutical use in steam sterilization applications. Keystone's PureClean™ Tyvek® material does not have a water soluble antistat agent applied to it during its manufacturing process.

• Uncoated Tyvek® for maximum breathability during sterilization
• Eliminate the risk of residue deposits on equipment post sterilization
• Manufactured and packaged in a controlled cleanroom environment
• Reduces labor costs and simplifies the conformance to wrapping SOP's
• Autoclavable at 121 to 125 °C
• Tear- and puncture-resistant, hydrophobic, lint-free
• Conveniently packaged, 100 per sealed poly bag

PureClean™ Tyvek® Muffs provide a convenient means to cover flasks, beakers, containers, media bottles, valves, pipes, and hoses. These covers are breathable and can be used to prevent particulates and microbial contamination from entering openings of any size. Since they are autoclavable, they can be used during sterilization to reduce the time-consuming wrapping of open containers. Each closure incorporates latex-free rubber elastic to create a positive seal around round shaped openings.
