O1100 Series Column Oven

The O1100 Series Column Oven incorporates imported thermostats and sensors for highly precise and stable temperature control. Advanced TPC and membrane heating technology ensures extended heater service life. Comprehensive alarm and short-circuit protection guarantee safe operation. The upgraded O1110 and O1120 models feature forced-air circulation, which significantly reduces temperature gradients and shortens heating time; their enlarged chamber accommodates two 10 mm × 300 mm columns. The O1120 further adds RS485 communication for seamless remote control via chromatography workstations.

Performance

The O1100 Series Column Oven provides reliable and precise temperature control for HPLC columns from 5 °C above ambient up to 99 °C, ensuring consistent retention times, high column efficiency, and excellent analytical reproducibility. Models with forced-air circulation (O1110, O1120) eliminate thermal gradients and accelerate temperature equilibration, while the O1120 enables remote method programming and real-time monitoring via RS485 communication with chromatography data workstations. With robust safety protections and a compact design, the series is ideal for pharmaceutical, biomedical, environmental, and quality control laboratories requiring dependable column temperature management.
