Manufacturer's Description: The XCell SureLock® Mini-Cell’s unique design allows you to run mini-gels quickly, easily, and leak-free without any clamps or grease. The set-up time is only 30 seconds; just drop the Buffer Core and the Gel Tension Wedge into the Lower Buffer Chamber, insert the gels, and pull the Gel Tension Wedge forward. The perfect no-leak seal results in no mess and consistent performance. Tough polycarbonate construction of the unit boosts durability. Retractable plugs, recessed jacks, and a specially designed lid enhance user safety. You can transfer with the optional XCell II™ Blot Module, using the same Lower Buffer Chamber.
