Store in a cool dry place (Optimum 8-15 degrees c). Use before the expiry date on the box. Do not use slides if there is any sign of growth before opening. Slides remain usable while the agar is smooth and attached to the slide. A small amount of water may collect in the bottom of the tube. This is condensate from the agar and does not affect performance, provided the agar still fills the tray.
Used slides should be incinerated, autoclaved or soaked in disinfectant for several hours before disposal.
