Abstract: Provided is sampling and testing device for the detection of specific molds, allergens, viruses, bacteria, fungi, and other protein containing substances. Embodiments of the device include a sampling member slideably engaged with a base that contains a lateral flow strip adapted to detect specific analytes of interest. The sampling member defines a solvent reservoir that stores an elution solvent in a fluid-tight manner before the device is used to sample and test environmental surfaces. During slideable withdrawal of the sampling member from the base, the elution solvent stored in the reservoir is automatically released to a wick assembly of the sampling member. The wick assembly includes a wick adapted to receive, distribute, and retain the elution solvent. After a user samples an environmental surface for an analyte of interest with the elution solvent wetted wick, the sampling member is returned to the base where the wick contacts the lateral flow strip contained in the base.

Abstract: A thermal imaging camera is provided which includes an outer housing, a core disposed substantially entirely within the housing, and a plurality of damping members disposed between the housing and the core to substantially fully suspend the core in the housing with the damping members.

Abstract: Provided is a demonstration apparatus comprising a top subassembly and a bottom subassembly. The top subassembly includes a reservoir adapted to contain a consumer product to be demonstrated. The consumer product has efficacy to produce a consumer-desired effect that is directly or indirectly observable. The bottom subassembly includes a vial containing a contaminant upon which the consumer product produces the consumer-desired effect. The top sub assembly and bottom subassembly are coupled to a reservoir seal element. Upon activation of the demonstration apparatus, the consumer product flows into the bottom subassembly and contacts the contaminant to produce the consumer-desired effect. Also provided, are a method of use for the demonstration apparatus and a kit containing the demonstration apparatus.

Abstract: Provided is sampling device and method for the detection of an analyte of interest on an environmental surface. The sampling device includes a first reservoir adapted to contain a first liquid, a second reservoir adapted to contain a second liquid, a swab holder coupled to the first reservoir and the second reservoir, a swab disposed within the swab holder, and an activation member coupled to the first and second reservoirs opposite the swab holder. After the swab is used to collect a sample from an environmental surface, and upon application of an activation force on the activation member, the first and second reservoirs are placed in fluid communication with the swab holder and the first and second liquids flow into the swab holder to contact the swab. The swab develops an indicator color if the sample of the environmental surface contained the analyte of interest.

Abstract: The present invention involves an optical assay device and method of use for the detection of an analyte of interest in a sample that conveniently allows control of the flow characteristics of the sample through the device without significant user intervention. The optical assay device includes a base having an absorbent material, and a member having an optically active test stack that is rotatably coupled to the base for rotation between a lowered position and a raised position. In the lowered position, the optically active test stack contacts the absorbent material for drawing the sample through the surface. In the raised position, the optically active test stack does not contact the absorbent material.

Abstract: The present invention relates to cost effective analytical instruments for determining the presence or amount of an analyte in a sample. The analytical instruments utilize an assay cartridge which has a sample receiving port and a rotatable carousel containing a plurality of reagent wells. Each reagent well includes a piston element for delivery of reagent to a test surface. The instrument is capable of indexing the assay cartridge to deliver sample and reagents to a test surface in a predetermined and flexibile manner, thus providing an assay protocol which is specific to the type of sample under analysis. The invention also relates to components, features, disposables, reagent delivery systems, accessories, and methods for using such instruments. Appropriate applications include infectious disease testing, cancer detection and monitoring, therapeutic drug level monitoring, allergy testing, environmental testing, food testing, diagnostic testing of human and veterinary samples, and off-line process testing.
