These new Transfer Units feature new hinged cassettes molded of tough, glass filled polyether sulfone for increased durability. The new gel cassettes provide a stiff backbone for the gel and membrane sandwiches. The hinged halves lock together for equal pressure across the gel. The grid design of the gel cassettes maximizes the open area for even transfers of gels up to 15 x 21 cm. The crucial element for uniform electrophoretic transfer, a uniform electrical field, is assured by spacing the electrode panels 10 cm apart and incorporating 140 cm of wire in an evenly-spaced pattern. For safety, the electrode panels are locked securely into the Transfer Unit, but can be easily removed for day-to-day use.

The TE 42 Tank Transfer unit is similar to the TE 62. It can efficiently transfer up to four 15 x 21 cm gels. This unit differs from the TE 62 in that the heat exchanger is optional on the TE 42. With the heat exchanger in place, the TE 42 can transfer a maximum of 2 gels.
