3.3 Casting the Gel
Gel Casting Using Gel WrapGasket Casting method
1. 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.
2. 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.
3. 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.
4. Place the spacers along side the inside edges
of the gasket. Be sure the rounded corner
end of each side spacer is facing the outside
bottom of the plate, following the radius of
the glass. Place bottom spacer in middle of
bottom edge with angled sides pointing down.
5. Place the notched plate on top of the bottom
assembly, starting from the bottom edge and gently
easing the plate down. Make sure the diamond
pencil marked side of the notched plate is the
side that will clamp to the unit. (see 3.2.1) Verify
the gasket is smooth around the edges and then
clamp along the bottom so that the clamps hold
the sandwich together over the bottom spacer.
6. Lift the assembly and stand it on the base of the
clamps. For leveling, push glass plate assembly
down until it stops against clamp body. Clamp the
sides of the assembly with additional casting clamps
on either side. As each clamp is attached, be sure
the gasket is aligned between the plates forming a
seal. Tilt the assembly to overhead light to confirm
“crush” of the gel wrap gasket against the glass.
