Ratek block for 20 x 1.9ml tubes

Ratek blocks are designed to suit the entire range of Ratek dry block heaters, but will also fit many other brands of dry block heaters. Block dimensions are L95mm x W75mm x H50mm and made from solid anodised aluminium. The solid construction gives rapid heat transfer and therefore rapid block heat-up when used in a Ratek dry block heater. Temperature uniformity is excellent and all blocks are supplied with a thermometer hole for reference.
