Jule Unveils Dual-Piston Gradient Former
The J5 Model gradient former is designed for pouring polyacrylamide gradient minigels or for pouring sucrose gradients into small centrifuge tubes up to 5 ml in total volume. The dual-piston design is intended to keep the fluid level in each chamber equal during gradient formation, regardless of the differences in density or viscosity of the two fluids being mixed. A trapped air bubble will not stop the flow, unlike gravity flow types, the company asserts. When the gradient former is attached to a peristaltic pump, the pistons are automatically drawn downward to keep the levels equal. Researchers also can dispense liquids manually by turning the lead screw to advance the pistons.
