A pressure transmission liquid for a cellular analyzer, a system for transferring a liquid cellular sample for analysis by a cellular analyzer, and a method for transferring a liquid cellar sample for analysis are disclosed. The pressure transmission liquid includes an aqueous solution which is isotonic and substantially non-conductive characteristics. The cellular analyzer includes a pipetting module having a pipetting tip, a device for positioning the pipetting module, a sensor for detecting a liquid level of a liquid cellular sample to be analyzed, a pressure transmission liquid, and a pressure transmission liquid conduit connected to the pipetting tip and the pressure transmission liquid reservoir.
