The Timberline TL-105 is a multi-feature HPLC column heater designed to meet the needs of busy chromatography labs.
- Built-in heat exchanger preheats the mobile
- phase reducing temperature gradients
- Extra-large heated cavity accommodates multiple analytical or semi-preparative columns
- Accommodates either an internal or external injection valve
- Easy access to heated cavity
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.
The TL-105 benchtop column heater utilizes our proprietary heat exchanger technology which reduces temperature gradients within the column, improving chromatographic efficiency. The column heater can control temperature from ambient 5 to 100 °C. High temperature versions to control up to 150 °C are available. The standard configuration heats flow up to 5 ml/min. The flow rate range can be extended to 10 ml/min with a pre-heater substitution. 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 70 mm (2.75”) deep cavity. Heated cavities are available from 44.5 cm (17.5”) to 58.5 cm (23.0”) in length. A built-in heat exchanger preheats the mobile phase and reduces temperature gradients within the column, improving chromatographic efficiency. In the unlikely event of a control failure, a thermal fuse cuts power to the heater to safeguard the heater, column, and laboratory.
