•The 10 x 10 cm electroblotter is meant to be a ‘personal’ semi-dry transfer device for one or two 8 x 10 cm or 10 x 10 cm mini-gels, stacked on top of each other. It is ideal for laboratory researchers who transfer only a limited number of gels. •The 20 x 20 cm device is a larger version of the 10 x 10 cm Semi-Dry Unit and can be used to transfer larger gels (up to 20 x 20 cm) or up to 4 mini-gels side by side. •Unique electrode design prevents incorrect electrode connection. •High quality robust acrylic construction guarantees durable, leak-free operation. •Both use the traditional stainless steel, platinized titanium electrodes. •These electroblotters can be used with gels run on horizontal or vertical devices.
