Product Detail

105 Low Voltage Power Supply -Highly compact, reliable and easy to use

Operating as a constant voltage power supply, the 105 is very simple to use. The adjustment knob and hi–lo range switch control the output, which is variable in 10-volt increments from 20 to 250 volts. One, two-position switch toggles the bright LED display from indicating output voltage to output current. The 105 is equipped with an over current detector for maximum safety. Like all Thermo products, the 105 is protected by our four-year warranty.

250-90 Low Voltage Power Supply - compact, lightweight and multipurpose

The 250-90 low voltage electrophoresis power supply is capable of producing up to 250 volts, 500 milliamps and 125 watts. This product operates in constant voltage or constant current with a continuously variable output. The 250-90 automatically crosses over from one mode of operation to the other when a preset limit is reached.   A dual function, auto ranging 24-hour up/down timer allows for more effective time management. Also included are four sets of output connectors which enables users to fully utilize the maximum capabilities of the 250-90 by running multiple chambers simultaneously.

The continuously variable output, constant current capability and automatic crossover expand the usefulness of this power supply.

DNA or RNA submarine gels, Mini PAGE and SDS-PAGE, and both small semi-dry and small tank-style blotters are easily accommodated by this versatile supply.
