Blocks
The blocks for use in heaters and dry baths have a variety of well quantities to process numerous samples at once. Models safely hold test tubes, microcentrifuge tubes, vials, conical-bottom centrifuge tubes, or PCR plates, tubes and strips in close contact during the heating process for ideal heat transference. Constructed from solid, anodized aluminum, the blocks offer maximum heat retention. Interchangeable, modular blocks mix samples and may support thermometer use for easy monitoring of conditions.

Reaction block systems for RH basic, RH digital, RCT basic, RET basic and RET control-visc magnetic hotplate stirrers
Supplier: IKA
Reaction blocks allow syntheses to be carried out in round-bottomed flasks at temperatures up to 180 °C, avoiding the use of oil baths. The system ensures optimum heat transfer from the heating plate directly into the medium. Uniform mixing is also guaranteed since there is no interference to the magnetic field from the aluminium blocks. Reaction blocks range from 100 to 5000 ml in size, and inserts accommodating round bottom flasks from 10 to 3000 ml are available. Due to the wide range of interchangeable inserts, this system can be used for a range of different applications with the RCT, RET and RH magnetic hotplate stirrers.
