Investigations into the causes of the bends (Decompression Illness). Diving Diseases Research Centre, Plymouth

 At present there is no complete explanation of what causes the bends. Measurement of changes in COP during diving by the Osmosis Unit demonstrated that intercompartmental fluid shifts result from changes in external pressure. Our studies suggest that blood volume increases with increasing barometric pressure. Extra fluid is eliminated in the kidneys. During decompression, fluid from the blood moves back into the interstitium reducing blood volume and increasing its concentration. The longer and deeper the dive the greater the increase in concentration and the lower the final circulating blood volume. A decreased blood volume gives less fluid space in which the increased gas concentrations can be dissolved. This in turn increases the likelihood of the development of micro-bubbles and the bends.  The development of rehydration drinks that can be consumed underwater during decompression is being considered.


Development of  a new theory of blood pressure (Pulse Reverse Osmosis)


Treatment of cardiac diseases is problematic at present as there is no realistic physico chemical model of the circulatory system that satisfactorily explains the etiology of hypertension, hypotension oedema and shock. Pulse reverse Osmosis suggests a physico chemical relationship between blood pressure, the pulse and the osmotic concentration of all the major components in the plasma. PRO suggests that an imbalance between the capillary pulse pressure and the osmotic pressure underlies the development of hypertension, hypotension, oedema and shock. Clinical testing of this hypothesis is presently taking place at Imperial College Medical School, London, and a various other physiology centers around the world.  


Setting up a water testing laboratory- Clearwater International


This start up company required a test facility to monitor water quality from their new water filtration device. The Osmosis Unit set up their water monitoring laboratory and trained Clearwater’s staff how to perform routine water analysis.

Simultaneous estimation of sugar and alcohol content during brewing (Cannongate Technology)


Monitoring both alcohol and sugar content in real time during brewing is a problem. The osmosis unit demonstrated that measurement of osmolality and MOP could show the change in concentration in both parameter throughout the brewing process. 

Development of a visible stethoscope - Euclid Healthcare


Most GP’s are over 50 years old. At this age everyone’s hearing is on the decline. This is a problem when one of your major diagnostic tools is the stethoscope. To address this problem, the Osmosis Unit developed a device to convert the audible signals into a visual trace on a computer. A company called Euclid Healthcare was set up to handle the development of this product.


Osmotic measurement (osmolality and colloid osmotic pressure)


Osmolality measurement (Baxters, Maelor,Glycologic, Bodycote, QCNW, Vitrolife)

Colloid osmotic pressure measurement (Maelor IVEX, Bodycote , Vitrolife, Braun).



The Osmosis Unit has unique experience in converting problems into practical products through the application of relevant research. If you have a problem and would like to develop it into a product, please contact us at
