The E-C Apparatus EC600-90 Electrophoresis Power Supply is manufactured by E-C Apparatus Corporation. The EC-600-90 Apparatus Electrophoresis Power Supply is controlled by three separate operating limits. An operating limit with a value above zero must be set for voltage, milliAmps, and watts in order to generate an output. The power supply is equipped with four sets of 4 mm output connectors, which are connected in parallel in order to run multiple chambers. The power supply operates in 3 modes: constant power, constant current or constant voltage. Constant power mode is especially crucial for certain laboratory techniques. The pre-owned products will be thoroughly cleaned and fully tested to perform at manufacturer specifications before shipping.
