The XCell4 SureLock Midi-Cell is a midi-gel electrophoresis system that allows you to quickly and easily perform simultaneous vertical electrophoresis of 1–4 midi gels. The Midi-Cell is built with tough polycarbonate to boost durability and features a specially designed lid to enhance user safety. The Midi-Cell is designed to dissipate heat effectively and evenly and ensure high-resolution results when using Invitrogen midi gels (8.7 cm x 13.3 cm).

Easy to use—simple assembly and operation for ultimate in ease of use. A single SureLock actuator seals all gels while allowing for zero force insertion and easy positioning for sample loading.
Flexible—run up to four midi-gels at once
Efficient—requires 25% less running buffer per gel than the Criterion Cell (340 mL vs 460 mL)

How the system works
The XCell4 SureLock Midi-Cell consists of a lower buffer chamber, two buffer cores, a lid with cables, a displacement dam, and a buffer dam. Electrophoresis of proteins on midi-gels in the XCell4 SureLock Midi-Cell is performed after assembling the buffer core with two midi-gels or one midi-gel and one buffer dam. The buffer core/gel assembly is inserted into the lower buffer chamber using a positive locking mechanism that seals the buffer core/gel assembly firmly into position and ensures leak-free electrophoresis. The buffer core/gel assembly creates separate upper buffer chambers for each gel and a common lower buffer chamber shared by all gels. The lid is placed onto the Midi-Cell, fitting in only one direction.

The Midi-Cell holds gels firmly with a simple gel tension wedge. When the lever on the gel tension wedge is pushed forward into the locked position, an even horizontal force is generated. This seals the gel/buffer core assembly firmly into position in the lower buffer chamber. The positive locking action of the gel tension wedge ensures a trouble-free, leak-free gel run every time.
