Protecting valuable humidity-sensitive items, such as reagents or electronics, is easy and fully automatic with Secador Auto-Desiccator Cabinets. The patented, electronic desiccant regeneration module recharges the desiccant every 20 minutes. Compared to other auto-desiccators that regenerate once every 4 to 6 hours, the Secador Auto-Desiccators attains a low %rH level on start-up and consistently maintains low %rH, especially with frequent entry to the desiccator interior.Key Features:Durastar co-polyester construction blocks 99% of UV light and resists staining, crazing and chemical attack Amber color models reduce visible light penetration by over 50%; perfect for storing light sensitive materials like reagents, analytical standards and investigational compoundsAutomatic dehumidification and desiccant regeneration cycle operates continuously every 20 minutesColor-indicating silica gel inside the desiccant regeneration module allows quick visual confirmation of desiccant statusLarge door with easy-to-view digital hygrometer maximizes access to interior space; includes patented seal design, tab latches and security loops for a padlock or tamper-evident seals; opens right to leftPerforated shelves facilitate circulation of dry airCompact 34.1W x 41.4cmD (13.4 x 16.3') footprint for space saving stacking up to 3 units highChoose from an extensive selection of sizes, styles and colors in 100, 120 or 230V (CE approved) models for use worldwideReplacement shelves available; 4.0 units can be converted from vertical to horizontal configuration or vice versa by turning the unit and ordering the appropriate number of shelvesReplacement Secador Auto Desiccator Module Desiccant BeadsU.S. Patents: 6,772,534; 6,834,920; 7,114,266; 7,318,630 and D474,626.
