Low Voltage Power Supplies (250 Volts)

The 105 and the 250-90 are simple to use, lightweight, multipurpose low voltage power supplies. Both models are perfect for DNA/RNA submarine electrophoresis.

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 foursets 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.

Mid-Range Power Supplies (500 Volts)

135-90 Power Supply
Capable of producing up to 500 volts and 500 milliamps, this power supply is ideal for PAGE, SDS-PAGE, DNA or RNA submarine gels as well as all types of small format transfer apparatus.

570-90 Power Supply
The 570-90 is capable of producing up to 500 volts or 2,500 milliamps. It is an excellent choice for running all types of electroblotting applications. Also ideal for PAGE, SDS-PAGE, and DNA or RNA submarine gels.

Product Description Code Size
The mid-range power supplies have all the safety and timer functions to make operation easy and safe. Dual-function timers ensure effective time management and automatic crossover when preset limits are achieved.

Manage Your Time Better
The mid range power supplies all have a dual-function, 100-hour timer that completes the experiment at the end of the time interval. This convenient timer also accrues elapsed time as the experiment progresses. This product has proven to be simple and efficient in assisting the user to better manage time.

Easy-to-Use
Designed with the simplicity in mind - a single knob controls the output and a single pushbutton selects the mode to be adjusted. Bright LED displays provide continuous information as it relates to output voltage, current and elapsed time. For added convenience, the power supplies remembers its last settings and comes equipped with a power fail memory.

Automatic Crossover Protects Your System
The automatic crossover function allows the power supply to switch over from one mode of operation to the other when the preset limit is reached, protecting your system and experiment.

Holding Voltage
This unique feature simplifies every experiment. It is designed to provide the operator with the option of applying a small voltage to the gel at the end of a timed experiment. This “holding voltage” minimizes sample diffusion prior to the disassembly of the electrophoresis apparatus.
