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.
