Abstract
Evaporation control for a fluid supply, such as used in a clinical analyzer, can be provided by utilizing a straw-like insert which is disposed into a fluid-containing bottle. The straw provides an increased diffusion length or “stagnant” zone. The bottle can also be configured to effectively reduce evaporation in a similar manner by providing a narrowed diameter prior to the fluid retaining portion of the bottle and by increasing the distance between the top of the bottle and the top of the fluid surface.
