C.B.S. œ Scientific Linear Gradient Maker 5
SECTION 1
General Information
1.1
Introduction
The C.B.S. Scientific line of linear gradient makers can be used to make reproducible gradients
easily up to 2000mls total volume by filling each cylindrical chamber. Eight different sizes of
linear gradient makers with side outlets are available. Gradient formation is controlled by a
Teflon valve centered between the two chambers. Gradient flow rate is controlled either by the
valve fitted on the outflow male luer adapter, or by a peristaltic pump.

Specifications
The smaller gradient makers (GM-20/40/100) have a support rod for attachment to a ring stand
and come with 10, 20, or 50ml chambers per side (Fig. 1).
