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. 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.

4.   Place the notched plate on top of the 
bottom assembly, starting from the bottom 
edge and gently easing the plate down.  
Verify the gasket is smooth around the 
edges and then clamp along the bottom.

 

 
 
 
 
 
 

5.   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.
