Cooling Core
The cooling core extends to the bottom of the graduated gel tube and houses the elution tube in its center. Cooling is recommended during polymerization as well as during electrophoresis.

Gel Tube Assembly
The gel tube assembly holds both the gel and the cooling core. The elution chamber cap and the gasket mounted on the graduated gel column make up the upper part of the elution chamber. Two gel tube assemblies are provided with the Model 491 Prep Cell.

Casting Stand
Gels are cast with the gel tube assembly mounted directly on the casting stand. The casting stand ensures that gels have perfectly flat lower surfaces. Inserting a spatula in the gel-release slot facilitates the removal of the gel from the casting stand after polymerization by allowing air to enter beneath the gasket and the gel.
