What do you need to know to choose the right desiccator?
Q. What size(s) are the items you need to store and in what quantity?
A. Interior volume of the desiccator and shelving should be considered.
Q. How important are ease and economy of use?
A. Each method of desiccation has advantages and trade-offs. Each user must determine the method that best serves their purposes. Using standard desiccants and regenerating them as needed is economical, but requires monitoring. There may also be more variability in your environment. An automated desiccator requires much less monitoring but uses electric power. Gas ported desiccators are quick to achieve relative humidity, but if the unit is accessed frequently, proportionately more gas will be needed to keep the desired low humidity level. Vacuum desiccators remove air and moisture and can be brought back to vacuum rather easily after opening but require a pump.
Once you have determined your most desirable method of desiccation, there are a variety of styles and sizes of desiccators to choose from.
