ACLAR® 33C Film, 8X10, 7.8 Mil

ACLAR® is made from fluorinated-chlorinated resins. There are four basic film types–the homopolymer ACLAR® Rx Series, the copolymers ACLAR® 22A and 33C and the new ACLAR® Cx. (Honeywell/Allied Signal). The chemical make-up of all ACLAR® products provide an exceptional moisture barrier. ACLAR® is crystal clear, biochemically inert, highly resistant to most chemicals and sterilizable by heat or radiation. ACLAR® is used widely in pharmaceutical, medical, sensitive electronics and military packaging.

ACLAR® 33C is a copolymer film consisting primarily of chlorotrifluoroethylene (CTFE). It offers an outstanding moisture barrier, excellent chemical resistance and minimal dimensional change (<2%), making it the best choice for use in microscopy.


  • Crystal clear, high UV transparency– ideal for use in UV curing of embedding resin in microscopy.
  • Chemically stable and biochemical\y inert– the product of choice for growing cell cultures.
  • Low dielectric constant, high electric strength and dissipation factor– offers excellent cell attachment even through lengthy processing procedures.
  • Low surface energy–and separates easily from epoxy.
  • Exhibits no detectable autofluorescence– ideal for fluorescent microscopy.
  • A non-flammable, non-aging co-polymer– which is suited for sterilization by heat or UV.
  • Crystalline melting point is 206°C (403°F)– stable in the SEM.
  • Flexible and soft– can be sectioned without damage to the ultramicrotome knives.
