OHAUS Dry Block Heater, Model, HB4DG, 4 blocks, Digital control

Multi-purpose Dry Block Heaters are ideal for applications that require temperature stability. The close tube-to-block contact enables maximum heat retention, resulting in efficient heating. High-wattage, constant-temp. analog models are an economical option, while digital models offer exceptional temp. uniformity & stability for applications that require repeatable results. Units hold optional interchangeable modular blocks with over 40 options.

• Delivering Exceptional Temperature Stability and Uniformity
• Accurate and Fast Sample Heating with PID Microprocessor Temperature Control (Digital Models)
• Digital Models can be Calibrated to an External Temperature Device
• Optional external temperature probe
• Holds interchangeable modular blocks
• Each of the five models accepts separate interchangeable modular blocks, accommodating various tube sizes from 0.2 mL micro-tubes to 50 mL centrifuge tubes. Each block has a thermometer well for measuring block temperature.
• Microprocessor Control: PID temperature control, with optional external RTD probe, offers a temperature stability as low as ± 0.1°C with a temperature uniformity as low as ± 0.1°C. Samples are heated to temperature quickly and accurately. Temperature is adjusted in ± 0.1°C increments.
• Caution Hot Indicator: Hot warning symbol light is illuminated when the temperature is above 40°C.
• Overshoot Protection: If the unit exceeds the set temperature by 10°C the unit will automatically stop heating.
• Operating Conditions: Units can be run in conditions from 18 to 33°C, 20% to 80% relative humidity,

non-condensing.

Applications: Denaturing proteins, DNA applications, ELISA and other immunoassay Studies, incubation andactivation of cultures, enzyme reactions, melting/boiling points, and a wide variety of other laboratory procedures.
