More Information:
The LabAlliance Model 605 Column Oven regulates temperature with precise control to increase the accuracy and consistency of chromatography work. The column heater, with its uniform and controlled temperature, guards against temperature changes throughout a day in a laboratory, even from temporary drafts, that can affect the reliability and repeatability of results.
Features of the Model 605:
All major elements are enclosed in the oven chamber
Constant temperature is maintained the entire length of the fluid path
Mobile phase is used as transfer medium so temperature is not affected by flow rate
Temperature is held to within ± 0.2 °C
Holds up to 6 analytical or GPC columns
No need for special blocks or inserts

From the manual:
The LC Column Oven is engineered to perform equally well as a dependable system for routine analyses or as a sophisticated research instrument. While ideal for HPLC applications, the LC Column Oven is also useful as an oven for general laboratory or industrial use. 1.1.1
Oven Features
The LC Column Oven features a novel low dispersion heat exchanger which heats the mobile phase and sample before it enters the column. The injected sample is maintained as a plug through the heat exchanger to insure against peak broadening. The temperature gradient across the column is minimized by the solvent preheating technique; the mobile phase encounters a stationary phase of uniform temperature from one end of the column to the other. (In conventional block-type column heaters or forced air column ovens, large temperature gradients can exist across the column; the mobile phase then encounters a stationary phase of increasing the temperature as it moves along the column. The thermal gradients reduce column efficiency and change selectivity.).
The LC Column Oven features an open-bed oven design which eliminates the need for specific blocks or inserts for each column size. Up to three 3/8-in. x 30 cm or four ¼-in. x 30 cm HPLC columns can be easily placed inside the oven. The oven chamber is large enough to accommodate a guard column and an analytical column for precise control of temperature conditions. The LC Column Oven has a side mount which accommodates the most popular manual and pneumatic injection valve brackets.
The LC Column Oven’s setpoint temperature can be controlled remotely with an external voltage source. A contact closure between two connections on the back panel initiates remote voltage control. A voltage of 0-10 volts DC will produce a setpoint temperature of 0 - 100°C. • The LC Column Oven can be controlled remotely with the RS-232 serial communications interface. The setpoint and current temperatures can be read and the setpoint temperature can be written. See Section 3 for a complete list of commands.
A thermal safety switch removes power from the heating element if the temperature reaches 118°C. This protects against damage to the column oven. • The LC Column Oven includes a corrosion resistant anodized aluminum column chamber for lightness, strength, and temperature uniformity. 1-2 Other features of the LC Column Oven include:
Inclined chamber and drain tube for leaks
LED readout on the front panel—displays the setpoint and current temperature in °C or °F, has a HEATING light to indicate when the heating element is receiving power, and a FAULT light to indicate a fault condition has occurred. • Tactile response, chemically resistant front panel keypad
Microprocessor advanced control
Platinum RTD temperature sensor for accuracy and stability
PID control algorithm
