The present invention provides a device for the determination of micro-organisms, comprising a vessel (1) closable with a cover (3) in which vessel is housed a nutrient medium carrier in the form of a longitudinal carrier body (2, 40) which has a plurality of troughs (10, 11, 12, 13, 41, 42, 45, 46) for the reception of nutrient substrate substances, the upper surfaces of which are provided with a removable cover, wherein at least one closable filler connection (19, 20, 43, 44), formed on the carrier body (2, 40) opens into each trough (10, 11, 12, 13, 41, 42, 45, 46).

Device for the determination of micro-organisms

The present invention provides a Petri dish, especially for culturing micro-organisms, comprising a circular lower dish and a cover loosely laid thereon. Projections are formed provided on the periphery of the inner surface of the cover and, matching depressions are formed on the rim of the lower dish. This permits adjusting a gap between the cover and dish for control of gas exchange between the interior of the Petri dish and the atmosphere.

Petri dish

The present invention provides a temperature-stabilizing packaging container for condensation sensitive, water containing products in closed tubes, especially semi-solid test media such as immersion nutrient substrate carriers for the determination of micro-organisms or the like. The packaging container comprises a strip-like, heat-insulating material, at least one of the surfaces of which is provided with a radiation-repelling, metallic covering.

Packaging container for sensitive products

.alpha.-Amino-.beta.-(N-benzylthiocarbamoylthio)propionic acid provides strong anti-bacterial and anti-mycotic action coupled with excellent stability and tolerability when administered orally in mustard oil therapy.
