The SliceMate 

 

Introduction 

The SliceMate provides temperature-controlled perfusion fluid to slice preparations 
required during analysis of electrophysiological properties. Originally developed as 
a modular sub-system for use with our unique SliceMaster – multi-channel 
recording system, the SliceMate is a novel design integrating what would normally 
be several separate sub-systems into a single line replaceable unit providing a 
robust, space efficient system. 

SliceMate Design 

The SliceMate housing integrates the tissue bath, heat exchanger / Peltier device 
and fluidic control valve within a dedicated Acetyl enclosure. The compact and 
precision design ensures system variables are minimised and that all SliceMates are 
identical in structure. 

Tissue Bath 

 

The brain bath has been developed to include features that simplify the 
equipment table requirements; vacuum suction ports, integrated reference 
electrode, thermistor temperature sensor and connectorized interface. The brain 
bath puck is replaceable as a modular component. The thermistor temperature 
sensors are precision devices which only require basic re-calibration if the brain 
bath or thermistor should require replacement.
