Introduction: The outstanding dehumidification performance of the Autodesiccator models are recommended for more perishable and expensive chemicals that require constant low humidity. Totally automatic, continual desiccation with silica beads, and regeneration every twenty minutes, keeps the relative humidity (RH) level in the Secador 4.0 Desiccator at a constant level. No longer does one have to tolerate a regeneration lag between cycles and there is a minimal change when opening the cabinet door. Two fans guarantee continuous air flow within the cabinet and continuous exhaust of humid air.
The material of construction is DuraStar® plastic which has all of the important mechanical and impact properties of polycarbonate for this application, but has the optical properties of an acrylic. Note that these cabinets, although they look and are highly robust and strong, they are not designed to be vacuum compatible. Therefore, do not attempt to pull a vacuum on these cabinets (you will ruin the cabinet) but select one of our vacuum compatible cabinets.
Features of the Secador 4.0 Desiccator Cabinet, Vertical:
Details of the desiccant: The desiccant is a non-particulate forming silica gel bead and for all practical purposes, are about as inert a material as one can get. The desiccant never comes in contact surface of the items being stored in the desiccator, and only come in contact with the air that is circulated around it. The desiccant has a long lifetime but should be checked to determine if it needs replacements.
Use as an evaporation chamber: If used as a controlled environment evaporation chamber, the Secador 4.0 can handle about 0.5 ml water per hour.

Secador Autodesiccator Cabinet Models - Vertical (Electrical service required) This is the model that operates silently and automatically, and the decissant never needs replacing since it is constantly being regenerated by the unique desiccant regeneration module.
Secador 4.0 Cabinets, Manual Operation (and non-electrical) These cabinets have all of the specifications of the automatic models except they do not have the automatic regeneration of the desiccant feature. From our own experience using these cabinets in our own laboratory operation, it would seem that for normal laboratory use, that is, where the door is being rather regularly opened and closed, the automatic model would be recommended. But if the cabinets are essentially for the long term storage of either samples, or components or other items sensitive to moisture, then quite probably the manual model will be just fine. And you will save some money as well.
Of course, if you are using the cabinets strictly for dust control, and you are going to be using them as a dust free storage area, the manual version will do just fine as well.
Like the automatic model, the manual model also has three perforated shelves, all movable and removable. Desiccant cartridges or capsules may be placed on or underneath the shelves. The door is hinged at the left side and has two latches on the right.
Available desiccants: SPI Supplies offers a full range of desiccants, such as the SPI Desiccant Capsules and the SPI Desiccating Canisters.
Secador Shelf The Secador 4.0 series cabinets can be easily converted from a horizontal model to a vertical model (or from the vertical model to the horizontal model) with the purchase of the proper shelving. Two shelves are needed to convert to the horizontal unit while three are needed to convert to the vertical unit.
