Static Dissipative Acrylic Desiccator Features:
- 1/4″ ESD Safe Static Dissipative Acrylic (Non-Out-Gassing)
- Prevents build-up of static charge as well as accumulation of harmful contamination.
- Electrostatic decay in less than 0.05 seconds per federal test standard 101C, method 4046.1
- Surface resistivity 106-108 Ohms / sq.
- Stainless steel plates provide full conductive grounding. They protect acrylic from surface abrasion and for this reason, we recommend them when compartment floors are utilized as shelves.
- Grounding wire connects from hinge to hard ground. All racks, shelves, plates, latches, as well as hinges connect to this common ground.
- Additionally, the static dissipative back plenum wall is removable.
Selecting Your Desiccator Model
- The desiccator selection process involves building the desiccator around the contents for maximum storage capacity.
- The storage contents dimensions [width / depth / height], weight, and quantity should be calculated.
- This information will assist in the selection of the model and dimensions for storage. (Add 1 inch to the depth for desiccators with a plenum chamber).
Shelf Maximum Weight Capacity:
Perforated Stainless Steel Shelves – 40 lbs. Capacity
1/4″ Solid Acrylic Shelves – 25 lbs. Capacity
3/8″ Solid Acrylic Shelves – 40 lbs. Capacity

Knowing the Difference between Clear and Static Dissipative Acrylic
Clear Acrylic Desiccator cabinet models (D) are recommended for non electro-static discharge (ESD) sensitive storage applications. In general, these acrylic desiccators are utilized in cleanroom storage of wafers, and other contents less susceptible to ESD discharge events.
Although acrylic desiccators may attain a highly charged condition, it can be mitigated with the proper precautions. Cleanrooms maintain 45/55% relative humidity control, which provides a layer of moisture on exposed surfaces, and in fact, this conductive layer facilitates discharging the static electricity to ground. TDI recommends that acrylic desiccators include our grounding feature in order to accelerate these discharges.
Static Dissipative Acrylic Desiccator cabinet models (SD) provide complete electro-static discharge protection for ESD sensitive storage including cleanroom and assembly components. The static dissipative acrylic material offers a surface resistivity of 106-108 Ohms/sq. and these desiccators cannot be tribocharged when properly grounded.
Static dissipative acrylic desiccators offer stainless steel shelves only, coupled with stainless steel shelf racks and plates, which are all common grounded to the desiccator and wire connected to hard ground. Grounding is used to provide static control to the desiccator and its contents. With this in mind, stainless steel plates are recommended to enhance grounding. They also protect from surface abrasion when the floor of each compartment is utilized as a shelf. Plates are mounted directly to each compartment floor.
More Desiccator Options
Stainless steel desiccators provide clean, high-density storage for both cleanroom and assembly applications. Compared to acrylic desiccators, stainless steel provides maximum weight capacity and long-term durability. Constructed of conductive stainless steel and in addition, wire grounding for ESD protection is available. Stainless desiccators meet stricter insurance requirements as well as providing part storage privacy. These desiccator cabinet models come in 2 or 3 stack single chambers in a specially designed stand, or as multiple chamber cabinets. The doors are made of static dissipative acrylic or tempered glass, depending on your requirements.
