Product Overview

All models feature precision digital PID control with bright dual line LED display which indicates set and current temperatures, combined with simple up and down temperature control buttons. Independent concealed heaters heat each block individually to achieve rapid heat-up times and excellent spacial uniformity.

A user-configurable process over-temp audible and visual alarm also provides the user with peace of mind. Perhaps the best new feature in the range is the capability to operate at up to 200° C as standard, allowing for a much wider range of digestion applications to be performed in addition to low temperature molecular and biological work.

Ratek’s most advanced block heaters to date offer simplicity with accuracy and can be run day in day out for any number of general lab applications.
Dry Block Heaters are used for applications such as the preservation of samples and reaction, enzyme digestions, enzyme activity studies, DNA amplification, incubation and activation of cultures, melting/boiling points and nucleid acid hybridisations.
