Cleaver Scientific offer the widest range of combs available of any gel tank manufacturer. They fit virtually every application from preparatory electrophoresis to high-throughput screening. They are height-adjustable without any requirement for specialist tools or comb holders, to give the user full control over well depth and sample-loading volume. The rigid comb back prevents heat-induced warping and reversible loading guides sit directly above each well to provide a convenient loading template for single- and multi-channel pipettes.
