Assembly Tray
Assembly Tray

Included assembly tray and roller — use the assembly tray for gel soaking, for sandwich assembly, and to ensure correct orientation of gel and blot.

The Criterion™ blotter provides a combination of blotting efficiency and flexibility in an easy-to-use unit.

Features and Benefits

  • Capacity to blot 2 Criterion gels or 4 Mini-PROTEAN® handcast or precast gels
  • Closely spaced electrodes produce maximum field strength and efficient transfers in 30 min to 1 hr for most proteins; overnight transfer at lower voltages is also an option
  • Included assembly tray can be used for gel soaking, sandwich assembly, and to ensure correct orientation of the gel and blot
  • Included roller removes air bubbles in the sandwich to ensure complete transfer
  • Included sealed cooling unit is sufficient for most transfers and absorbs heat generated during rapid transfers
  • Optional cooling coil is available for applications that require precise temperature control
  • Cassette handles allow easy removal from the tank, and overflow chambers keep your laboratory bench dry

Applications and Uses

  • Western blotting
  • Nucleic acid transfer
