Corning® PYREXPLUS® glassware brings you the best of both worlds – the extraordinary chemical inertness of genuine PYREX® borosilicate glass on the inside plus the additional protection of a tough plastic coating on the outside.

The thick PYREXPLUS® polyvinyl chloride (PVC) coating delivers longer product life for more safety:

  • Doubles the resistance to impact fracture of coated glassware compared to uncoated
  • Helps prevent surface checks and scratches extending product life
  • Reduces the chance of breakage if PYREXPLUS® glassware is banged or dropped AND it helps contain spills if breakage does occur
  • Less slippery and easier to grip than glass

  • PYREXPLUS glassware can be successfully sterilized by autoclaving using a liquid or dry cycle which involves no vacuum or low vacuum (5 inches Hg.)
  • PYREXPLUS glassware is completely microwave safe.  
  • The recommended temperature use range for PYREXPLUS glassware is 10°C to 80°C.
  • PYREXPLUS glassware should not be exposed to temperatures below -20°C or above 110°C.

    PYREXPLUS Aspirator Bottles and Filter Flasks provide an extra layer of safety from injuries from glass fragments during implosions. However, in keeping with safe laboratory practice, always use a safety shield around evacuated containers.
  • The PYREXPLUS coating is designed to resist leakage resulting from a brief chemical exposure that might occur if the vessel is broken. Prolonged and/or repeated chemical exposure of the coating to esters, aldehydes, ketones, chlorinated or aromatic solvents and concentrated acids should be avoided.
