Thermostat Cabinets

  • Versatile
  • Powerful
  • Cost-effective

To incubate samples at a constant, desired temperature during the reaction period, a thermostat cabinet is necessary. WTW offers thermostat cabinets in various sizes with a variably adjustable temperature range of 10 °C - 40 °C (50 °F - 104 °F) and a power supply of 230 V/50 Hz. Temperature accuracy lies at ±1 °C deviation from the set temperature.
Because the samples must be stirred, the thermostat cabinets are fitted with internal power sockets. 2 – 4 shelves are available, according to the thermostat cabinet size, thus enabling simultaneous temperature control of up to 48 standard BOD samples, or 4 IS 12 or IS 6-Var stirrer platforms.
The largest model, TS 1006-i is especially suited for special applications, as the space between the 4 shelves allows for 1.5 l vessels or flasks with side nozzles.
The sizes TS 606/2-i aTS 606/4-i are available with transparent insulating glass doors and are especially suited for use with the OxiTop® Control system. Data can be recalled through the closed glass door, to avoid temperature fluctuations caused by opening the door.
