This application describes a composition comprising an alkali metal permanganate and a water soluble nitrate salt and a method of controlling the sulfide content and the odor of sulfur containing waste water by adding the composition of the invention to the waste water.

Composition and method for sulfide control

A growth container for laboratory organisms such as fungi, TB bacilli, yeast, virus or bacteria in which a well for the growth medium is spaced inwardly from an outer and higher wall. A lid snaps in place over the dish to substantially enclose the growth medium. An absorbent material, preferably a ring of filter paper, is placed in the space between the well and the outer dish wall to humidify the container when the material is wet, and to collect condensation from the lid which may include dangerous spores. Condensation is collected from a blocking ring on the underside of the lid by inversion of the dish and absorption onto a filter paper ring. An access opening in the lid permits material to be removed from or added to the growth medium with the lid only partially disengaged. The well may contain a single growth medium or a number of segregated growth compartments. A method of obtaining a slide specimen is described in which a slide member is placed over the well and the organism is grown until it adheres to the underside of the slide member. The organism is then severed and the slide member and adhered specimen removed from the container. Substantially undamaged specimens are thus obtained quickly and with safety.

Growth container and method for pathogenic and other laboratory organisms

A self-contained pipet washer and dryer which utilizes a container assembly within which is located a quantity of the pipets that are to be washed and dryed. An acid storage tank is included which includes a volume of acid which is to supply acid into the container to soak the pipets for a period of time. Tap water is to be supplied into the container to initially rinse the pipets after the acid soaking. A second source of rinsing solution, in the form of deionized water, is provided to function as a final rinse for the pipets. Heated air is to then be blown across the pipets to dry the pipets.
