ACLAR® Film

ACLAR Film provides an O2 barrier when flat embedding specimens for electron microscopy and light microscopy
it separates easily from epoxy and is chemically inert

aclar

Epoxy embedments sandwiched between ACLAR® sheets

aclar pull away

ACLAR® pulled away from the flat specimen embedment.

cutting aclar

Cut out the area of interest and glue it on a 00 cylinder for sectioning.

00 cylinder


disc punchDisc Punches are available in four sizes:

5/16" (7.9mm)
3/8" (9.5mm)
7/16 (11.1mm)
1/2" (12.7mm)

cut aclarFor comparative TEM and SEM procedures, cut an ACLAR® circle in half and compare the two after fixation (Kingsley3); use a blunt needle to mark.

Press between glass plates

aclar vibratome

Fresh material is cut on a Vibratome®, treated with HRP and placed on ACLAR cut into a slide shape - observe under LM - if OK, process for TEM on the slide.

see Kingsley3 for explanation of most points below

separates easily from epoxy

transparent fluorinated-chlorinated thermoplastic which contains no volatile components

chemically inert, for all practical purposes

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 microscopy

sterilizable

gives flat sections

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

Description and Ordering ACLAR® Film

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's 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 sterilized3.

ACLAR® is offered in sheet form, 8 x 12.5" in package quantities of 10 or 25.
