For IPG strips and IEF gels

Developed in partnership with SERVA GmbH, the prestigious electrophoresis chemicals company based in Heidelberg, Germany, the IEF-SYS unit has been optimised for isoelectric focusing applications using SERVA IPG BlueStrips and SERVALYT™ PRECOTES™ and PreNet™ IEF gels, which are also available through Scie-Plas.

A 27 x 27cm ceramic cooling plate can be connected to the optional JULABO chiller to maintain either two 125mm square or one 245 x 125mm SERVALYT™ PRECOTES™ IEF gels, or a maximum of thirty SERVA IPG Bluestrips, up to 24cm in length, at their respective operating temperatures of 4 and 20°C.

An acrylic electrode frame sits directly on the ceramic cooling plate for IEF with SERVALYT™ PRECOTES™ gels, whereas a glass electrode frame may be employed when using IPG strips.  In both applications, the positive and negative electrodes can be adjusted within the electrode frame - so that the voltage may be fine-tuned along each length of gel or IPG strip - and then held in position by a glass electrode weight.

The IEF-SYS unit can be also adapted for wick-based electrophoresis with horizontal precast gels.
