 BATH

 

 Bath Circulator

 

 

 

 

 
External and internal circulating with
powerful pumping capacity
CW-G series is designed for controlling temperature in external instrumentation, or for immersion application. Pump pressure is adjustable in five stages and all models come with built-in tab water cooling coil.
 
 
Performance Features
Operating features
• 5 above room temperature to 150
• Microprocess PID control/ Auto-tuning/ Calibration
• Digital timer: 1 min to 99 hr 59 min, delayed ON/ OFF
• Over-temperature limiter and low fluid level protection
• 3 different temperature values memorable without auto-tuning
• Digital LED display (0.1 resolution) with splash-proof keypads
• RS-232 interface available
 
Constructional features
• Exclusive variable-speed pump to liquid viscosity for accurate, stable, and efficient temperature management
  (1 to 3 steps of pump for internal circulation/ 4 and 5 steps for external circulation)
• Powerful pressure and suction pumps provide contrast pressure and flow rate over the full
  temperature range
• Baffle plate screens circulating pump, heater and sensor to minimize shaking bath fluids and protect sample
  and operators from direct contact
• Dry-running protection; automated heating element cut-off and audible and visual warning
• Seamless stainless steel tank with a reservoir drain that resists corrosion and make cleaning easy
• Space saving design uses minimal bench space

1) If you operate the unit in 1 to 3 steps of pump, the temperature range can be from Amb. +5 but in 4 and 5 steps,
    the range will be from Amb. +15.
2) The heat-up time is measured on a 230V electrical condition with 1000W heater power.

 

 

Accessories & Options


Highly durable stainless steel racks with adjustable angle and tube height support.
Do not need any other base plates to use it, simply release and mount racks directly.


Ideal for holding a wide variety of tubes, flasks, and other glassware.
All component are made of stainless steel. (for all models)


Additional suction function for powerful external/ internal circulating.
Maximum suction flow rate is 10.0 liters per minute. (only for CW-G and RW-G series)
* The additional suction function is needed to have a prior request.
