Open the CIPO recordAbstract From the Canadian patent
A flow cytometer for the analysis of large particles or small multicellular organisms may experience unstable flow because of the large diameter of the flow chamber. The use of a sheath fluid or a sheath and sample with addition of a viscosity-increasing agent to give a viscosity higher than that of water ensures that flow in the pre-analysis section will be fully developed laminar flow, and that the flow in the analysis section will be laminar. This allows accurate analysis and sorting of large particles or analysis and sorting of smaller particles at an increased rate of speed. Water-soluble polymers are preferred because they increase fluid velocity with negligible osmotic …

Why it's free to use
- Filed December 29, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 29, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 29, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
