Innovative photometer technology

Using the new photometer technology for the strip result reading enables the instrument to deliver complete information for blood testing: concentration of hemoglobin and counting result of erythrocytes up to 50 cells/μL by differentiating the intact and lysed erythrocytes.

Using the new photometer technology enables cobas u 601 to spot errors from the testing process and eliminate wrong results. If there is dust on the strip, or if the strip was bent, or if not enough/too much urine sample was pipetted onto the strip, the instrument can give error messages to indicate the reasons.

Chemstrip® technology

Chemstrip® technology has more than 50 years history in the market. It is proven technology and is continuing to be used on cobas u 601 urine analyzer.
