Methods for the calculation of weight loss by water evaporation from small biopsy specimens

Abstract

The rate of loss of weight by water evaporation was obtained for biopsies taken from lamprey muscle, and this was related to the original weight of each sample. Hence, two alternative methods are proposed for the correction of small biopsy weights to allow for this evaporation in air. It is suggested that these methods may permit good approximations for corrections in similar conditions to those used, and that the methods for evaluating empirical coefficients may be applied elsewhere to allow for other situations.
