1. Introduction: Hoefer SG15,
SG30, SG50, and SG100
gradient makers
The Hoefer ® SG gradient makers are designed
for producing linear gradients of aqueous solu-
tions ranging in volume from 15–100 ml. The
gradient makers are machined from solid blocks
of acrylic plastic. They are suitable for casting
acrylamide pore gradient gels, casting immobi-
lized pH gradient gels, pouring density gradients
for centrifugal sedimentation separations and
delivering salt gradients for low pressure chro-
matography systems.
The gradient makers have a white Luer outlet
fitting that can take either tubing with female
