General description

The SG series gradient formers are designed for producing linear gradients of aqueous solutions ranging in volume from 15–100 ml. The SG 50 and SG 100 units can be used to form convex and concave exponential gradients with the addition of an exponential gradient plunger accessory. The small units (SG 15, SG 30, SG 50, and SG 100) are machined from solid blocks of acrylic plastic. They are suitable for casting acrylamide pore gradient gels, casting immobilized pH gradient gels, pouring density gradients for centrifugal sedimentation separations and delivering salt gradients for low pressure chromatography systems.Ring stand support rod included.
