ALab™ HB105-S1/S2 & HB150-S1/S2 Dry Bath Series
Product Detail
ALab™ HB105-S1/S2 & HB150-S1/S2 Dry Bath Series — four digital dry baths with an LED display and an external PT1000 temperature sensor: room temperature +5 up to 105°C (HB105) or 150°C (HB150), with ±0.2°C temperature uniformity at 37°C.

The HB105-S1, HB105-S2, HB150-S1 and HB150-S2 are microprocessor controlled digital dry baths that offer control over both temperature and time, eliminating the need for an external thermometer or timer. They are used to thaw, boil, incubate and warm samples for different applications in molecular biology, assay preparation, tissue/cell culture, biochemistry, genetics, histology, clinical, environmental and industrial laboratories. Single and double heat block modules are available, the highest temperature is up to 150°C, a buzzer alerts when the time is up and an external temperature sensor PT1000 is listed. The HB105 models cover room temp+5 to 105°C and the HB150 models room temp+5 to 150°C; the S1 models are rated 100 W and the S2 models 200 W. The photo shows the HB105-S1 with its lid open; the specification table lists the models side by side.
