The Cole-Parmer WB-200 Water Bath, 6.6 L, 220 VAC (78905-21) is a digital heated water bath designed for general-purpose laboratory temperature control. It provides an ambient +5 to 100 °C operating range, ±0.2 °C temperature stability and PID control within a 6.6 L stainless steel tank. The unit operates from a 220–240 VAC, 50/60 Hz power supply and includes a stainless steel gabled cover and perforated bottom plate.
Key Features
- Broad laboratory heating range, supporting set temperatures from ambient +5 to 100 °C
- Stable temperature performance, maintaining the bath temperature within ±0.2 °C
- Compact 6.6 L reservoir, suited to routine benchtop heating procedures
- Digital PID regulation, providing controlled heating through a PT100 temperature sensor
- Clear LCD monitoring, showing the measured temperature, set temperature, timer and operating status
- Built-in overtemperature protection, switching off the heating elements when an overshoot condition is detected
- Automatic operation recovery, resuming heating after the temperature falls below the overshoot threshold
- Corrosion-resistant wetted surfaces, with a 304 stainless steel tank for routine laboratory use
- Simplified cleaning and water changes, using rounded tank corners and an integral drain valve
- Reduced heat loss, with an attached 304 stainless steel gabled cover supporting consistent bath conditions
- Flexible cycle scheduling, with a 0 to 5999-minute timer, delayed heating start and audible completion alarm
- Adaptable sample organisation, accepting two module widths of optional tube racks and an optional two-flask plate for 33 to 92 mm diameter flasks
Note: Optional tube racks and holed flask plates are sold separately. This 6.6 L model does not accept tube rack 78905-29.
Benefits
- Handles routine heating procedures without requiring a large-capacity laboratory bath.
- Lets operators check the actual temperature, programmed temperature and remaining cycle time from one display.
- Helps protect samples by interrupting heating when an excessive temperature condition occurs.
- Reduces time spent draining and cleaning the bath between laboratory procedures.
- Allows heating cycles to be scheduled for a more convenient start time.
- Supports different tube and flask arrangements through compatible optional rack systems.
