Performance data of automatic desiccators

Test procedure: After a pre drying period of 10 minutes, a humidity of 100% is simulated in an automatic desiccator. The desiccator is switched on, the door remains closed tightly until the end of the test. The curves show relative humidityGlossaryrelative humidityPercentage ratio between water vapor pressure and saturated water vapor pressure over a clear and even water surface. On this basis it is easy to evaluate how quickly evaporation will proceed or how large is the danger of condensation. The quantity of water vapor which would be needed for saturation increases with increasing temperature. Similarly the relative humidity of a given air mass falls with increasing temperature. Temperature is therefore an important factor in assessing relative humidity and condensation. v time

Temperature is therefore an important factor in assessing relative humidity and condensation. inside the desiccator is down to 10%  due to automatic drying. Frequent controls are not necessary. The storage space is bigger since it is not necessary to use silica gelGlossarysilica gelSilica gel is a colourless amorphous silicic acid with a gel-like consistency. It has a large inner surface area. It is very hygroscopic and can be used as gelling agent, filtering or absorption material and desiccant. Normally coupled with an indicator, silica gel changes colour as soon as it absorbs water; the gel remains pourable and dimensionally stable even in saturated condition. It can be regenerated on a metallic sieve or on a baking tray at approx. 90–110 °C (a microwave oven is not suitable for regeneration!). and process errors are avoided.
