The O1100+ Series Column Oven incorporates imported temperature controllers and sensors for highly precise and stable temperature regulation. Advanced membrane heating technology significantly extends the heater’s service life. The O1110+ features forced-air circulation, which shortens heating time and substantially reduces temperature gradients, while the enlarged chamber accommodates two 10 mm × 300 mm columns. The O1120+ adds RS485 communication, enabling remote control and monitoring via chromatography workstations. An integrated one‑piece structure ensures convenient operation and installation.

The O1100+ Series Column Oven delivers accurate and stable temperature control for HPLC columns from 5 °C above ambient up to 99 °C, ensuring reproducible retention times, high column efficiency, and consistent analytical results. The forced-air circulation in both models eliminates thermal gradients and accelerates temperature equilibration, while the O1120+ enables remote method programming and real‑time monitoring via RS485 communication. With its compact footprint, low power consumption, and robust construction, the O1100+ series is an ideal solution for pharmaceutical, biomedical, environmental, and quality control laboratories requiring reliable column temperature management.
