ACLAR® Film
[elementor-template id=”186167″]
ACLAR® Film provides an oxygen barrier when flat embedding specimens for electron microscopy and light microscopy,
it separates easily from epoxy and is chemically inert
The 1968 paper1 by E. B. Masurovsky and R.P. Bunge was the first to describe and clearly demonstrate the useful chemical and physical properties of ACLAR® for both tissue culture and electron microscopic purposes.
It was first used in the space program and its properties were found to be interesting for biomedical research (personal communication, Dr. E. Masurovsky). Subsequent work by others developed ACLAR® applications; attention is brought to that done by Mawe, et al 2, and the comprehensive ACLAR® study by Kingsley and Cole3.
ACLAR® overcomes a number of problems regarding the processing of tissue culture cells, epoxy embedments, sectioning and observations because of its chemical inertness, non-stick property, glass clarity, flexibility and smooth surface.
It may be cut with scissors or blades and does not damage microtomy knives. It is unsurpassed in moisture barrier protection, transparent to UV and is plasticizer and stabilizer free. It is nonflammable, nonaging and has a low dielectric constant and dissipation. It is high in dielectric strength. ACLAR® can be sterilized.
Features of ACLAR® Film:
- Separates easily from epoxy
- Transparent fluorinated-chlorinated thermoplastic which contains no volatile components
- Chemically inert, for all practical purposes, ideal for growing cell cultures
- Cells adhere to it readily and remain attached after fixation, dehydration and critical point drying or embedding
- Accepts heavy metal sputter coating
- Stable in the scanning electron microscope; melting point 202°C
- ACLAR® is as transparent as glass
- Fluorescence microscopy possible since ACLAR® exhibits no detectable autofluorescence
- Can be sectioned and does not damage ultramicrotomy knives
- Considerably simplifies the preparation of cultured cells for all types of microscopysterilizable
- Gives flat sections
- Soft, can be sectioned
- Smooth surface makes light microscopy observations possible
- Does not degrade under UV or gamma ray radiation
- Used as an O2 barrier when flat embedding methacrylate or acrylic resins
ACLAR® is offered in sheet form, 8 x 12.5″ (203 x 318mm) with 7.8 mil (0.2mm) thickness.
