3.4 Gel Casting Using Gel Wrap™ Gasket Casting Method
1. Place all components in an authorized work area. You will need: glass plate set, Gel
Wrap™ Gasket, spacer set, comb, 3 GPC-0002 clamps, and polyacrylamide solu-
tion. Prepare and clean glass plates by hand washing both plates with a high quality
lab detergent followed by a complete rinsing with dH
2
O. Air-dry or use a lint-free
tissue. Spray/wipe the chosen inner surfaces of the plate set with 95% ethanol and
dry with lint-free tissue.
2. Hold the rectangular back plate with
the rounded bottom corners and start
applying the gasket around one side of
the glass plate. Note: one side of the “U”
shaped gasket is flat, and the other side
has tubing that will act as a seal around
the spacers.
3. When applying the gasket over the
rounded corners of the back glass plate,
make sure the notches on the gasket
align with the rounded corners of the
glass plate. Once the gasket is pushed
over the bottom edge and corners, work
it down the remaining side.
4. Place the gasketed plate on the lab
bench with the tubing side up, and
extend the bottom of the plate over the
edge of the bench, approximately ¾ of
an inch. Place the spacers along side
the inside edges of the gasket. Be sure
the rounded corner end of each spacer
is facing the outside bottom of the plate,
following the radius of the glass.
