Be sure to thoroughly mix the milk sample before drawing it into the tube.

Traditionally, if you were reading a creamatocrit with calipers or a hematocrit reader, you wouldn’t be able to discern anything less than a .5% difference (and that takes really good eyesight). The Creamatocrit Plus™ is digital and is programmed with the regression equation, so it takes precision to an entirely different level. It would be unlikely that you would get two identical results for that reason. Minor differences in the way you read the creamatocrit or place the cursor will produce minor changes in creamatocrit percentage. You wouldn’t be able to see these minor changes with the older methods, but because this is electronic and mathematical, they will appear. You may want to spin two tubes of the milk sample and average the two results for a total.

It will not affect the result. Simply ignore it when marking the interfaces on the tube.

No, Creamatocrit Plus™ tubes must be used. Their specific type and inside diameter ensure accurate results are calculated.

Some sealants do not work well. Use HemataSealTM sealant.

Be sure you use the following procedure for sealing the tubes:

1. Fill the tube ½ to ¾ full.
2. Let the milk flow down the tube until it is near the dry end. Then, place your finger over the wet end of the tube to stop the flow. (Stop the milk before it gets to the area where the sealant will go – that area should remain dry.)
3. Immediately insert the dry end vertically into the sealant, pushing it to the bottom of the tray. When removing it from the sealant, twist the tube to prevent the sealing plug from being extracted. Repeat.
4. Gently tap the sealed end of the tube on a flat surface to help ensure proper sealant contact in the tube.

Note: Do not push the holes out of the clay with your finger, as it can result in a thinned layer of sealant or air bubbles.

The centrifuge includes a control strip. It can be used to confirm that the tube reader is working correctly. The manual provides directions for performing a spin time and a tachometer test.

Some sealants do not work well with milk. HemataSealTM performs well.
