Abstract: A formula and method for rapid neutralization of formaldehyde solutions and vapor is provided. The invention comprises a matrix or medium upon which a mixture of urea, acid, calcium chloride and water is applied and dried. When the treated matrix or medium comes into contact with formaldehyde solution or vapor, the hydroscopic nature of the calcium chloride dried on the medium quickly absorbs and neutralizes the formaldehyde, irreversibly changing the formaldehyde molecules to a nonhazardous and nontoxic polymer. This reduces the risk of exposure to formaldehyde solution and vapor by the technician handling the material.

Abstract: An apparatus and method for transferring liquids between containers in a closed dispensing system is provided. The closed dispensing system comprises a dispensing container, an exchange chamber, a receiving container, and connectors between the dispensing container, exchange chamber and receiving container. Liquid is released from the dispensing container into the exchange chamber where it collects, creating hydraulic head and forcing the liquid into the receiving container. As the liquid collects in the receiving container, the atmosphere in the receiving container is forced through the exchange chamber and into the dispensing container. This provides an exchange of liquid and atmosphere between the dispensing container and receiving container without the liquid or vapors being exposed to the outside atmosphere. This reduces the risk of exposure to potentially hazardous or otherwise harmful liquids or vapors by the operator transferring the liquid between the containers, and the outside environment.

Abstract: An apparatus and method for disinfecting a cryostat is provided. The cryostat disinfecting device comprises an ultraviolet emitter, a pulsed power control system, a mirrored cover and a safety shield. The device is lowered into a cryostat chamber and produces high intensity pulsed UV energy, disinfecting the cryostat chamber. After disinfection, the device is removed from the cryostat for storage or use on another cryostat. This provides mobility and access for disinfecting cryostats under continuous daily use conditions, and reduces the exposure risk of biological and chemical hazards to the operator.
