INTRODUCTION
The Gel Dryer enables the drying of large gels up to 33.6 cm x 42.3 cm (13.2 in.
x 16.7 in.) or any combination of smaller gels for preservation or subsequent processing
such as auto-radiography or densitometry. The Gel Dryer provides even controlled
heating adjustable from 40° to 80°C. An external vacuum source of at least 50 liters per
minute is recommended. Drying times will vary depending on the vacuum source gel
concentration and gel thickness.

INTRODUCTION
General Description
The Gel Dryer consists of a cast aluminum platen which is evenly heated by an 800 watt
heater. A perforated sheet supports the gel during drying. A porous polyethylene sheet
lays on top of the gel, and a permanently attached silicone rubber sheet provides a seal.
Separate timers are provided for the heating element and the vacuum pump, which is
plugged into the electrical outlet at the right side of the unit.

INTRODUCTION
Component Identification (115V unit shown)
1. Gel Dryer Fuse. The Gel Dryer Fuse protects the unit from an electrical overload.
The fuse is rated at 10 amps time delay (2 fuses, each 10 amps time delay for the 230
model).
2. Platen. The cast aluminum platen allows for a uniform distribution of heat during
drying. The platen is Teflon® coated to minimize sticking.
3. Screen. The porous screen supports the gel during the drying process, preventing it
from sticking to the platen.
4. Porous Polyethylene Sheet. The porous polyethylene sheet covers the gel during the
drying process, preventing the gel from sticking to the silicone rubber sheet.
5. Temperature Adjustment Knob. The drying temperature is controlled by setting the
adjustment from 40° to 80°C.
6. Heater Timer. The Heater Timer sets the length of time that the heater operates. It
may be adjusted from 0 to 4 hours (0 to 4 hours on the 230 volt model).
7. Heater Indicator Lamp. The Heater Indicator Lamp illuminates while the heating
element is in operation. As the platen temperature reaches the selected drying temperature, the light will begin to blink, and then go out when the preset temperature is
reached.
8. Vacuum Inlet. The l/4 inch hose barb on the rear of the platen connects the Gel
Dryer to the vacuum source.
9. Vacuum Pump Timer. The Vacuum Pump Timer sets the length of time that the
separate vacuum pump (not included) operates. It may be adjusted from 0 to 4 hours
(0 to 4 hours on the 230 volt model).
10. Vacuum Pump Electrical Outlet. The 10 amp outlet (5 amp for the 230 volt model)
is directly controlled by the Vacuum Timer.
11. Vacuum Pump Outlet Fuse (115V units). The Vacuum Pump Outlet Fuse protects
the Vacuum Pump Electrical Outlet from an overload. The fuse is rated at 10 Amps
time delay. 230V Units: There is no fuse specifically for this outlet on 230 volt units.
The fuses in Item #1 above (2 each at 10 amps time delay) protect the units entire
electrical system from overloads.
12. Silicone Rubber Sheet. The flexible rubber sheet provides a vacuum seal during the
drying process.
13. Mylar Sheet. (not shown) Is used in place of the porous polyethylene sheet.
