Extended Range Dry Bath

The Digital Dry Bath (HB120-S) is a compact benchtop dry thermostat with extended high-temperature capability up to 120°C, designed for specialized molecular biology applications, protein denaturation, and high-temperature diagnostic assay preparation in clinical and research laboratories . With a temperature range from room temperature +5°C to 120°C and temperature control accuracy of ±0.5°C, this dry bath provides consistent, uniform heating for protocols requiring temperatures above the standard 100°C boiling point .

The HB120-S features a microprocessor-controlled system with LED display for real-time temperature and time monitoring, an intuitive control knob for simple operation without complex menus, and interchangeable aluminum heating blocks compatible with various tube formats and sizes . The unit supports both timing mode (0 to 99 hours 59 minutes) and continuous operation mode, with built-in temperature self-calibration function for long-term accuracy .

For the molecular biologist and clinical laboratory scientist, the HB120-S supports complete heat inactivation of restriction enzymes and heat-labile enzymes (preventing interference with downstream diagnostic assays), protein denaturation for SDS-PAGE and Western blotting, DNA denaturation for GC-rich templates and challenging PCR protocols, and high-temperature sample preparation for specialized diagnostic workflows .

Safety features include over-temperature protection and an insulated lid that prevents heat loss and contamination . The extended temperature range (up to 120°C) enables specialized protocols requiring higher temperatures than standard dry baths, making the HB120-S an essential tool for reference laboratories and molecular diagnostics facilities.

For the patient undergoing specialized molecular testing, the HB120-S's extended temperature capability ensures complete enzyme inactivation, thorough DNA denaturation for challenging templates, and reliable high-temperature sample preparation—supporting accurate diagnostic results for complex genetic conditions, infectious diseases, and oncology testing .
