coagulant

In practice it remains the cheapest and safest coagulant known at present.

The net saving in coagulant alone amounted to 30 cents per million gallons.

Instead the anti-coagulant is placed in the bottom of the bucket prior to the commencement of collection.

If the quantity of coagulant has been calculated to an average nicety, the serum should be just dubiously free from milkiness.

Any but the very slightest trace of milkiness in the serum indicates an insufficiency of coagulant.
