Block Heaters

Block heaters and coolers use interchangeable, modular blocks for housing tubes, vials, reaction vessels, and other laboratory containers. Both analogue and digital models offer repeatable results and temperature stability. An array of blocks can be purchased separately as well to meet specific needs. Shaking heaters and coolers completely mix samples at a designated temperature for homogenous blends. Sample concentrators feature quick sample evaporation when used with block heaters.

Dry block thermostat for cuvettes, LT 200

Supplier: Hach

A digestion step often has to be carried out before key parameters can be determined. For these parameters, the LT 200 thermostat complements the LANGE cuvette test system. Two separately controllable heating blocks enable cuvettes and reaction vessels to be digested at identical or different temperatures and time settings. The LT 200 has a digital timer with an automatic switch-off and acoustic signal. Two transparent splash protection lids cover the thermostat while it is heating. The integrated over-temperature feature and the insulated external casing provide additional safety.
