Humidity control

Humidity control - to significantly reduce evaporation

Controlled humidity is an important factor when working with microtiter plates or when cultivating in a flask for long periods (e.g. cell cultures). With humidification evaporation can be markedly reduced.

Digital PID control, incorporating a microprocessor, ensures exact regulation of the humidity. In Kuhner incubator shakers humidification is by means of an electrically heated water bath with automatic water refill. The condensing water is also returned to the basin.

The relative humidity is measured by a capacitive sensor.


Door heaters

Condensation is avoided by heating the door frames and windows.


Calibration of the humidity controller

Calibration is simple and requires the following

  • a Type ER-15 calibration device for a 15mm sensor
  • a Rotronic humidity standard (lithium chloride solution) e.g. for 80% humidity,
  • a shaker serial interface and personal computer with the installed Kuhner Insight software
  The system is checked by producing a known humidity in a small chamber which is mounted on the sensor element. Unsaturated lithium chloride solutions are used as humidity standards. Different solutions are available for various humidity values. These solutions can be supplied by Kuhner.


EcoDew®

EcoDew

The newly developed EcoDew®-Technology provides precise humidity control without requiring a cooling unit. This system was developed especially for customers working with humidity and temperatures of more than 10°C above ambient, e.g. cell culture cultivations or microtiter plate cultivations.

The EcoDew® option is available for ISF1-Z and LT-X incubator shakers. A simple retrofitting of existing incubator shakers is possible.


Advantages:

  • eco-friendly (less power consumption, no cooling unit required)
  • silent operation
  • easy to clean
  • retrofittable
