Treatment System Utilizing a Fluid Replacement Cartridge

Abstract

A treatment system, in particular a system using a brine solution for chilling or freezing tissue samples, includes a working vessel wherein samples can be treated, and a replacement cartridge having a first compartment with an inlet, and a second compartment with an outlet, wherein the second compartment is collapsible. A first conduit connects the working vessel to the inlet; and a second conduit connects the outlet to the working vessel. Used working fluid can be moved from the tank to the first compartment via the first conduit, and fresh working in the second compartment can be forced into the second conduit as the second compartment collapses. A holding vessel can be provided in the first conduit for holding used fluid, or in the second conduit for holding the fresh fluid, while the working vessel is cleaned.
