Bioanalytical Systems LC-22C Temperature Controller

The Bioanalytical Systems LC-22C Temperature Controller is a versatile instrument designed for precise temperature regulation in laboratory environments, particularly for liquid chromatography applications. It is capable of controlling two independent devices, such as heating mantles, heat tapes, electrochemical cell preheaters, and column heating blocks. The controller features a multi-turn front-panel potentiometer for setting the desired temperature control point. Power to the heating unit is regulated by a temperature sensor. For BAS-manufactured heating devices, the temperature sensor is integrated. For controlling external devices, a universal probe (part no. EW-8116) is available for separate purchase. The LC-22C can be used in conjunction with BAS LC-23A or LC-23C Column Heating Compartments to maintain stable temperatures for analytical columns.

### Technical Specifications

* **Control Capability:** Dual channel, independently controls two separate heating devices.
* **Temperature Setting:** Multi-turn front-panel potentiometer.
* **Temperature Regulation:** Via temperature sensor integrated into BAS heating devices, or external universal probe (part no. EW-8116, sold separately).
* **Compatibility:**
* Can be combined with LC-23A Column Heating Compartments for 15, 25, or 30 cm analytical columns.
* Can be combined with LC-23C Column Heating Compartments for two to four 10 or 15 cm columns.
* Can control detector preheater modules or cartridge column heaters.
* **Heating Device Power Limit:** 75 watts maximum per channel.
* **Sensor Input:** Compatible with integrated sensors in BAS heaters or an external universal probe.
* **Indicator:** LED light indicates when the heater has achieved the setpoint and is maintaining temperature.
* **Analog Output:** Provides a voltage output that can be recorded by a strip chart recorder (full scale input of 10 volts).

### Electrical Specifications

* **Line Voltage:** Selectable for 115V/50-60Hz or 230V/50-60Hz via a rear panel selector switch.
* **Power Cable:** Standard 3-prong power cable.
* **Grounding:** Requires connection to a standard, grounded power outlet for safety. Use of an appropriate adapter and secure grounding is recommended if a grounded outlet is unavailable.

### Interfaces

* **Heater Output Jacks:** Two jacks labeled “HTR 1” and “HTR 2” for connecting heating devices.
* **Sensor Input Jacks:** Two jacks labeled “PROBE 1” and “PROBE 2” for connecting temperature sensors or universal probes.
* **Recorder Output:** Analog voltage output for external recording devices.

### Physical Characteristics

* **Dimensions:** Specific physical dimensions are not detailed in the provided documentation.
* **Weight:** Specific weight is not detailed in the provided documentation.
* **Construction:** Designed for laboratory use.

### Compatibility

* **LC Columns:** Compatible with standard 15, 25, or 30 cm analytical columns when used with LC-23A heating compartments. Compatible with 10 or 15 cm columns when used with LC-23C heating compartments.
* **Heating Devices:** Suitable for heating mantles, heat tapes, electrochemical cell preheaters, and column heating blocks.

### Maintenance

* The LC-22C, LC-23A, LC-23C, and cell preheaters are designed to be essentially maintenance-free.
* **Recommendations:**
* Avoid corrosive laboratory environments.
* Prevent damage to signal cables (avoid crimping, do not stack heavy items).
* Clean spills inside column heaters promptly.
* Avoid contact of organic solvents with insulating materials in LC-23C covers.
