Cell dry weight measurement

WebDry Weight vs Cell Count Dry weight is the weight of the product the water removed. At Reed Mariculture, we measure dry weight in our microalgae products by placing 100 grams of algal concentrate into an 80°C drying oven and heating until a stable weight is reached. The weight of the residue is then used to calcula WebThe main limitation of the dry weight measurement is that it is relatively insensitive and inaccurate – it is difficult to way with accuracy less than 1 mg, but this dry weight.
