Column Heater

The Timberline TL-105 is a multi-feature HPLC column heater designed to meet the needs of busy chromatography labs. The TL-105’s microprocessor controlled heating creates stable and accurate temperature control to provide reproducible retention times and stable baselines for temperature sensitive detectors such as refractometers, electrochemical, and conductivity. Increasing column temperatures reduces peak tailing due to surface silanol interactions, improves efficiency, reduces backpressure, and prevents column contamination.

Description

The TL-105/TL-105 D bench top column heaters utilize our proprietary heat exchanger technology which reduces temperature gradients within the column, improving chromatographic efficiency. This HPLC fluid heater can control temperature from ambient +5 to 100℃.  High temperature versions to control up to 150℃ are available.  An optional injection or switching valve can be mounted in the heated compartment.

The column, preheater, and installed valves in the heated cavity are easily accessed through an insulated cover held in place on the top of the unit with thumbscrews. Inadvertent solvent leaks are directed away from heater electronics via a drain tube in the heated compartment connected to a bulkhead fitting on back of unit.

The extra-large heated cavity accommodates multiple analytical or semi-preparative HPLC columns that can be stacked into the 2.75″ (70mm) deep cavity. Heated cavities are available from 17.5” (44.5cm) to 23.0” (58.5cm) in length.

For higher flow rates, Timberline offers a TL-105-D Column Heater with Dual Temperature Control, which allows for independent temperature control of both the column and the mobile phase.  For pricing info, click here.
