Abstract: Disclosed herein are embodiments of a wiring box. The wiring box can include: a cavity formed by walls having an internal surface inside the cavity and an external surface; and a cable entry device disposed through a hole in a first wall of the walls. The cable entry device can include: a support element that retains a grommet in the hole, wherein the support element includes a stop, a grip extending from the stop, and shutters extending from the stop and defining an opening, wherein the opening converges away from the stop, the grip attaches the support element to the first wall, and wherein the grommet includes a rim, a sidewall extending from the rim and converging toward a diaphragm.

Abstract: Use of a disposable filtration capsule with a non-occluded membrane filter element in the place of a standard spiral wound cartridge allows for the more rapid and quantitative filtration, recovery, and quantitation of microorganisms in liquid, particularly surface waters, well water, tap water, and the like. The capsule allows a severe reduction in the water sample size tested, substantially minimizes risks of cross-contamination, and provides a leak-proof vessel for shipment. Risk of infection of laboratory personnel and time of analysis are both reduced. Costs of measuring contamination by microorganisms such as Giardia and Cryptosporidium is lowered significantly while increasing the accuracy and dependability of the measurement.
