O3220 Column Oven

The O3220 Column Oven incorporates PID subsection control technology for rapid temperature ramping with minimal overshoot, significantly reducing equilibration time. A high-precision temperature sensor combined with built-in calibration algorithms ensures accuracy ≤ ±0.5 °C and precision ≤ 0.1 °C. Forced-air circulation minimizes temperature gradients inside the chamber, while an integrated mobile phase preheating coil guarantees constant solvent temperature for enhanced separation reproducibility. Comprehensive safety features include overtemperature alarm, short-circuit protection, and power‑outage memory. The oven is fully controllable via LAN using Kromstation or W5100 workstations, and its highly integrated STM32 microcontroller with SMD packaging improves reliability and reduces board size.

Performance

The O3220 Column Oven provides precise and stable temperature control for HPLC columns from 5 °C above ambient up to 85 °C, ensuring consistent retention times, high column efficiency, and excellent analytical repeatability. Its rapid heating and low overshoot design shortens method cycle times, while the forced-air circulation and integrated solvent preheating eliminate thermal gradients and baseline disturbances. Fully integrated with Kromstation/W5100 chromatography data workstations via LAN, the oven supports automated method programming, real-temperature monitoring, and multi-level safety alarms (overtemperature, short-circuit, leakage response). With its robust construction, user-friendly interface, and low maintenance requirements, the O3220 is ideally suited for pharmaceutical, biomedical, environmental, and quality control laboratories demanding reliable and reproducible temperature control for routine and high-throughput HPLC analyses.
