The CBS Scientific GM-40 Linear Gradient Maker is used to reproduce gradients at various volumes up to 200 mls. It features two cylindrical solution chambers with a Teflon valve between them to control gradient formation. Gradient flow can be controlled with either a fitted outlet valve or peristaltic pump.
Designed for use in sucrose density gradient centrifugation, gradient gel electrophoresis, and liquid chromatography.
The total volume for the GM-40 is 40ml; 20ml per chamber.
