Bio-rad biorad 583 electrophoresis gel vacuum dryer
* Min. Vacuum Reg: 125 Torr / 25" Hg
Model 583 Gel Dryer - The Model 583 gel dryer has 3 preprogrammed drying cycles to provide optimum drying for any type of gel, particularly sequencing gels. Precision-controlled temperature regulation helps prevent gel cracking. The exclusive design incorporates a floating heating element in the lid to heat the gel from the top while the vacuum pulls vapor from the bottom. This design ensures uniform heating to speed drying. Gel dryers that heat and pull vacuum from the bottom take longer to dry gels, and the gels are more susceptible to cracking.
Preset Drying Cycles - The Model 583 gel dryer has 3 microprocessor-controlled heating cycles that provide optimum drying for different types of gels. Gradient gels require a gentle heating cycle to reduce thermal stress and prevent cracking. The gradient gel drying cycle slowly heats to a set temperature at 1 C per minute. The sequencing gel drying cycle eliminates the need to preheat the dryer, speeding drying times by rapidly heating to 90 C and slowly equilibrating to the set temperature. The SDS-PAGE drying cycle is similar to conventional gel dryers. The dryer's heating element reaches a set temperature and holds that temperature for a preset time.
Quick-Seal Track for Instantaneous Gasket Seal - Simply apply vacuum, and the quick-seal track around the drying surface produces immediate sealing of the gasket. This groove also ensures an airtight seal throughout each drying cycle.
Superior Temperature Control - Microprocessor control maintains precise temperature control throughout the drying cycle by continuously monitoring and adjusting the temperature at the heating element surface. Any temperature between 50 and 90 C can be selected with the digital selection key.
Memory - The set drying conditions are retained in memory. Push the start button to recall the setting for the next run.
LED Display - The LED displays temperature and time, giving exact dryer temperature and how much time is left in the cycle.
Drying Surface - The Model 583 gel dryer is especially suited for drying sequencing gels, or multiple standard-size gels. The drying surface is 35 x 45 cm. The dryer incorporates lid-mounted heater elements which heat gels from the top. Vacuum is pulled from the bottom through the porous gel support, distributing the vacuum evenly so that gels dry without cracking. The transparent sealing gasket allows monitoring gels during the drying cycle.
Drying Supports - Filter paper is an excellent support for drying stained gels. Sequencing gel filter paper provides stronger adhesion of filter paper to the gel for lifting fragile sequencing gels from glass plates. The cellophane membranes provide a clear gel for transmission densitometry or presentations on overhead projectors.
Vacuum Requirements - The Model 583 gel dryer requires a minimum vacuum of 25" Hg (125 Torr) and an initial capacity of 20 to 30 L per minute, which is more than most house vacuum systems can provide consistently. Mechanical vacuum pumps, such as the HydroTech vacuum pump, are recommended. The HydroTech vacuum pump produces a vacuum of 29" of Hg (23.4 Torr) or better, and has a 28 L per minute capacity. With a mechanical vacuum pump, the Model 583 gel dryer generally dries 10% or 12% acrylamide gels in about an hour.
New Gel-Drying Solution - Bio-Rad's gel-drying solution, a pretreatment for polyacrylamide gels, helps prevent gel cracking during vacuum or air drying. Just 30 minutes of equilibration before drying gels prevents excessive gel swelling and gel cracking.
