Product Description
Hold samples at a steady temperature without the mess, contamination risk or evaporation of a water bath. These 4-block dry block heaters accept four interchangeable modular blocks, chosen from more than 40 options, so the same unit can incubate microtubes one day and heat test tubes or vials the next. The four-block footprint suits busy labs running several tube sizes at once.
This listing is for OHAUS item number 30392066: Analog Dry Block Heater HB4AL, 4 Block, 120V, Up to 150 °C. Close tube-to-block contact delivers efficient heating and maximum heat retention, and blocks change without tools. Housings are painted steel with a support rod holder and locking knob, and power is 120V through a detachable 3-wire cord. Digital models offer touchpad control, an LED display, an audible alarm, temperature calibration and overshoot protection, while analog models use dual-adjustment knobs and need an external thermometer for setpoint checks.
