Manufacturer: Yamato — Japan
Overview
The HF Series comprises the HF100 and HF200 heating blocks from Yamato Scientific, both designed for quick heat-up. Both models provide precise temperature adjustment accuracy of ±0.2°C with a calibration off-set function and accept 10 types of aluminum block. The HF100 holds one aluminum block while the larger HF200 holds two.
Precise Temperature Control
Both the HF100 and HF200 provide temperature adjustment accuracy of ±0.2°C at 200°C using a φ16.5 testing tube, thanks to a calibration off-set function, and both accept 10 types of aluminum block.
