    Abstract: The device for testing reverse osmosis membranes provides for the quick and efficient testing of the transport properties of reverse osmosis membranes at a fixed pressure over a fixed period of time. The device includes a first chamber adapted for receiving a volume of de-ionized water and a second chamber adapted for receiving a volume of brine. In use, a reverse osmosis membrane to be tested is clamped between the first and second chambers and a pressurized inert gas, such as gaseous nitrogen, is injected into the second chamber at known pressure to initiate reverse osmosis transport. The transport is carried out at the known pressure for a fixed period of time, after which the concentration of brine volume of water in the first chamber is measured.

    Abstract: Vessel for transdermal diffusion cell testing includes a container defining an interior chamber having an opening against which skin is placed, and a casing arranged partially around and spaced apart from part of the container to define a compartment therebetween. The chamber retains a saline solution and is not in flow communication with the compartment through which water is circulated. The vessel includes separate inlet ports and outlet ports, each including a conduit communicating with the chamber or compartment. The outlet port of the chamber is arranged above the inlet port of the chamber, proximate the opening of the chamber, and is angled downward relative to a horizontal upper surface of the container against which skin being tested is placed. Tilting of the vessel prior to or during introduction of solution prevents air bubbles from remaining between the skin and the solution.

The device may be configured to be placed in fluid communication with a sample solution containing a solute and a solvent. The filter membrane may provide selective fluid communication between the solution and the exchange chamber. The separator may separate the exchange chamber from the sensing chamber and cause a change in a condition of the sensing chamber corresponding to a change of a condition of the exchange chamber. The sensor may sense the condition pertaining to the sensing chamber and calculate the concentration of the sample solution corresponding to this change.
