For blood sampling to perform ESR determination, the Sarstedt range includes the S-Monovette® and S-Sedivette® systems.

As with the S-Monovette®, blood is drawn by either the aspiration or the vacuum principle, allowing the collection tech-nique best suited to fit the individual patient's vein conditions.

A 2.8 ml volume of blood is drawn into the S-Sedivette® pre-dosed with 0.7 ml citrate (mixing ratio 1:5). After collection, the citrate blood is thoroughly mixed in the Sarrnix® M 200. For manual handling, a pre-dosed glass bead is used for mixing.

For ESR measurement, place the S-Sedivette® into the sedimentation rack and use the knurled thumb screw to adjust the sample level to zero.

After one hour, read the sedimentation value from the converted graduation. The value corresponds to the mm value of the Westergren method.

The practical rack enables parallax-free reading.
