Thanks to the use of a plug - in power supply giving only a low voltage of 9 V DC the danger of electrical shock during the use of the LAMBDA OMNICOLL fraction collector and sampler has been virtually eliminated.

If the fraction collector is not used for an extended period of time, disconnect it from the mains. A modern miniaturized switching power supply is used, which has only a negligible consumption of electric current when the fraction collector is not in use.
