With the PROTEAN Plus multi-casting chamber, you can cast up to 12 gels of 1.0, 1.5, or 2.0 mm thickness simultaneously. The chamber accommodates both 20 and 25 cm wide PROTEAN Plus hinged spacer plates. Acrylic blocks act as space fillers when fewer than 12 gels are cast, and a leveling bubble ensures level interfaces. Gradient gels are cast through a bottom filling port for reproducibility.
