Instruction Manual peqPOWER 250 Volt Power Supply
IMPORTANT GUIDELINES
Introduction
The important guidelines for operating the peqPOWER 250 Volt Power Supply are provided in this sec-
tion. We recommend that you carefully review these guidelines before operating the instrument.
Important
For best results, do NOT use the peqPOWER 250 Volt Power Supply at its maximum electrical load lim-
its. Variations in buffer conditions can result in exceeding the power supply’s maximum voltage, current,
or power output capacity and produce undesirable variations in electrophoretic separations.
General Operating Instructions
Follow the instructions below to operate the peqPOWER 250 Volt Power Supply.
Turn on the peqPOWER 250 Volt Power Supply using the power switch on the rear of the in-
strument. Upon start-up, the current settings appear on the screen.
Use the START/PAUSE and STOP keys and output jacks for applications.
Use the CONSTANT key to set up operation mode.
Recommendation
The duration of electrophoresis can be defined in time (hours/minutes). When using this or any electro-
phoresis product, we recommend that you adhere to the protocols given in the electrophoresis product
manuals, and durations, specified in time.
Important
For best results, follow these important guidelines when running multiple gels and electrophoresis units
concurrently.
For example:
• Avoid running samples of widely differing salt concentrations or sample buffers at the same time or on
the same gel.
• Properly prepare and desalt your samples.
Note: Variations in conductivity due to differences in buffer salt concentrations can affect the run of all
the samples run at the same time.
