Secador Techni-Dome Vacuum Desiccator

65-liter capacity Holds items up to 18” high or wide Ample quantities of standards, samples, electronics or other high value items can be safeguarded in the new Secador Techni-Dome Vacuum Desiccator. The largest domed desiccator of its kind, this patented model offers up to 4 times more volume, 65 liters (4,000 cu. in.) than most other large benchtop units. With space for items up to 18” (45 cm) tall or wide including racks, trays and instruments, this Vacuum Desiccator provides for much more storage in a single chamber than traditional plastic or glass vacuum desiccator units. All contents can be easily viewed through the desiccator's clear polycarbonate top and bottom. This laboratory grade plastic material is resistant to most common chemicals and cleans easily. All plastic construction ensures that there is no possibility of corrosion.  A molded-in ring allows the dome top to rest safely, inverted on the lab bench, when removed. Safety locator pins prevent the top half from slipping off the bottom half when raising one side of the lid to add or remove samples. Two round polypropylene shelves - 14.5” and 9” in diameter - maximize storage capacity and can be lifted out for easy access or to accommodate awkward sized items.  These high strength desiccators will hold a full vacuum (29” Hg, 737 mm) at room temperature for 24 hours and remain airtight even if not under vacuum. The included gasket, with an application of vacuum grease assures a tight seal down to 0°C. The polypropylene stopcock has a Teflon® plug that turns easily to allow a slow, turbulence free entrance of air, which minimizes disturbance of contents. The stopcock has a high visibility red handle and accepts 1/4” (6.4 mm) I.D. tubing.
