Submerged horizontal agarose gel electrophoresis is one of the primary tools for molecular biology as an easy economic and efficient technique for separation of nucleic acids as well as analysis of PCR-amplified fragments. UV transparent gel tray for ease of gel viewing. Comb teeth designed to provide sharp band. Buffer recirculation ports to afford recirculation or cooling of buffer to avoid interference in separation. 25 x 12cm gel with 54 or 27 wells per comb.
