1.3 Safety
The instrument is for research purposes only.
Power to the Criterion Blotter cell is supplied by an external DC voltage power supply.
This power supply must be ground isolated in such a way that the DC voltage output floats
with respect to ground. All of Bio-Rad’s power supplies meet this important safety
requirement. Regardless of which power supply is used, the maximum specified operating
parameters for the cell are:
300 VDC Maximum voltage limit
200 Watts Maximum power limit
50 °C Maximum ambient temperature limit
Current to the cell, provided from the external power supply, enters the unit through the
lid assembly, providing a safety interlock to the user. Current to the cell is broken when the
lid is removed. Do not attempt to circumvent this safety interlock, and always turn the power
supply off before removing the lid, or when working with the cell in any way.
The Criterion Blotter is certified to meet EN61010-1* safety standard for safety of
laboratory equipment. Certified products are safe to use when operated in accordance with the
instruction manual. This safety certification does not extend to other equipment or
accessories not EN61010-1 certified, even when connected to the Criterion Blotter.
This instrument should not be modified or altered in any way. Alteration of this instrument
will void the manufacturer's warranty, void the EN61010-1 safety certification and create a
potential safety hazard for the user.
