1. Introduction
The GE Healthcare Electrophoresis Power Supply EPS 301 is a high quality, high precision and
safe power supply for electrophoresis applications that require a maximum of 300 volts, 400 mA and 80
W.
EPS 301 is primarily designed for the following techniques:
1. Submarine DNA electrophoresis
2. Electroblotting
3. Immuno electrophoresis
4. Mini polyacrylamide gel electrophoresis
Electrophoresis separations can be controlled by voltage or current. The EPS 301 automatically switches
over the controlling parameter according to programmed limits and conductivity variations in the
system.
Two electrophoresis units can be connected to the EPS 301 and run with the same programmed method
at one time.
2. Safety information
2.1 Safety precautcions
Because this instrument can develop sufficient voltage and current to produce a lethal shock, extreme
caution should be exercised in its operation.
The power supply should only be used by properly trained operators. Read this entire manual before
using this power supply and use only according to the manufacturer’s instructions.
1. This instrument is designed for indoor use only.
2. The instrument must always be used with the earth lead of the power cord correctly grounded to
earth at the mains outlet.
3. To permit sufficient cooling, ensure that the vents in the rear and sides of the instrument are not
covered.
4. Do not operate the instrument in extreme humidity (above 95%). Avoid condensation by letting the
unit equilibrate to ambient temperature when taking the power supply from a colder to a warmer
environment.
5. Keep the instrument as dry and clean as possible. Wipe regularly with a soft damp cloth. Let the
power supply dry completely before use. If wetted, unplug the power supply until the instrument is
dry.
6. Use only undamaged electrical wire and equipment specified for the voltages you will use. High
voltage electrical wires should be in accordance with IEC 1010-2-031:1993. All equipment connected
to high voltage should be in accordance with IEC 1010-1:1993.
2.2 Built-in safety features
The EPS 301 has been tested and complies with the IEC 61010-1 (EN 61010-1) electrical safety
standard.
