Popis:	The reproducibility of weighing the mass of small-size glass Ascartte and Drierite absorption tubes with 0.25-mm capillaries on the Garner balance has been investigated. A standard error of estimate for the Ascarite tube was found to be ±1.65μg and for the Drierite tube ±2.65μg. Corresponding figures for light-weight aluminum absorption tubes with 0.34-mm capillaries were considerably higher. Filled glass absorption tubes standing idle in the room were found to exhibit weight increases with respect to time of the order of 0.201μg/min. for Ascarite and 0.251μg/min, for indicating Drierite. Tubes with larger capillaries (0.34mm) showed a more rapid weight gain.
