Picture-346_450pxCheck Mark Laboratory

Check Mark Laboratory is a division of Dairy One and one of the leading manual chemistry laboratories in the Northeast. All laboratory testing is done using AOAC approved methods. The laboratory conducts chemistry testing for fat, total protein, true protein, total solids, casein, lactose, and direct microscopic somatic cell count.  Check Mark can analyze any liquid dairy product for these components.  These may include but are not limited to: heavy cream, whey, retentate, yogurt, milk replacement products, reconstituted powders, or non-bovine milk.

When sending samples, please make sure to include a completed copy of the Sample Submission Form.

The Check Mark laboratory also manufactures raw bovine milk calibration standards each week to be used in other labs across the region. We can also develop customized calibration standards specifically for your IR analyzer to monitor your specific dairy product.

The component calibration samples (used to calibrate for fat, protein, etc) are shipped on Tuesdays via UPS and the results are made available by Thursday afternoon.  The somatic cell control samples are shipped on Wednesdays.  Shipping and handling is included in the prices, with Next Day or Second Day at an additional cost.  Customer pays the fee to return the shipping container.
