An apparatus determines soiling of an object and includes a rinsing zone for rinsing off dirt particles built up on an object with a fluid. A collecting arrangement includes a retaining device for capturing the dirt particles rinsed off from the object and a measuring device measures a physical parameter of the captured dirt particles. A transport system moves the dirt particles captured with the retaining device to the measuring device to permit measuring the physical parameter of the captured dirt particles.

Provided herein are methods and compositions to effectively isolate nucleic acids using protein-based sample collection matrices.

A method is disclosed comprising providing a biological sample on a swab, directing a spray of charged droplets onto a surface of the swab in order to generate a plurality of analyte ions, and analysing the analyte ions.

The present invention relates to a test film for detecting surface particles in a clean room in order to prevent inferior products by measuring the contamination level of the clean room using the surface particles. The present invention provides a test film for detecting surface particles in a cleanroom, the test film comprising a substrate which has a predetermined thickness and is formed of a transparent synthetic resin material; a first adhesive layer which is formed at one side of the substrate and collects the surface particles; a release film which is adhered to the first adhesive layer and is separated from the first adhesive layer when the surface particles are collected; a second adhesive layer which is formed at the other side of the substrate; and a protective film which is adhered to the second adhesive layer so as to protect the substrate and has gradations indicated thereon. According to the present invention, there is an effect in that it is possible to easily and quickly check whether or not a clean room is contaminated by collecting, on the adhesive layer-applied surface of a substrate to which an adhesive is applied, surface particles adhered to an object to be measured, and then measuring the number, size, distribution, etc. of the surface particles with the naked eye or using instruments such as a light, a magnifier, a microscope, or the like.

A specimen extraction kit includes a flexible tubular container configured to contain an extraction liquid, two holding portions opposed to each other and arranged at opposite sides of the tubular container, a coupling portion that couples the opposing holding portions, and a bending rib arranged on each of the opposing holding portions and configured to bend the tubular container and an extraction subject.

The invention relates to a test set (1) for a photometric measuring device, comprising a mixing container (2) which has a filling opening (3) and comprising a metering container (8) which can be sealingly inserted into the filling opening (3) of the mixing container (2) and which contains a liquid reagent (13) in a closed cavity (9). The cavity (9) has a closure plunger (11), which can be moved axially in the cavity (9), at a first end of the metering container (8), said closure plunger generating a specifiable filling pressure in the reagent (13), and the metering container (8) has a closure membrane (10) at a second metering container and which can be inserted into the mixing container (2). According to the invention, the closure membrane (10) is equipped with a predetermined breaking point (20) which breaks open when the filling pressure is exceeded in a defined manner as a result of an axial movement of the closure plunger (11), said predetermined breaking point (20) of the closure membrane (10) being formed as a linearly extending material taper of the closure membrane (10), wherein the taper is arranged eccentrically in the region of an opening (24) in the base (23) of the substantially cylindrical metering container (8).

Sampling device for samples containing DNA in particular, with a sample-collecting area provided at the free end of an elongate holding device, wherein the sample-collecting area is designed to be separable from the sampling device.

An alignment tool has a body with a top cavity. The top cavity is open on a top side and configured to receive the dispenser housing of a dispenser or a sampling medium head of a sampling medium on which to place the dispenser housing. The sampling medium head has a sample collection area. The body has a bottom cavity configured to receive a hammer arm. The body has one or more sampling media cavities disposed between the top cavity and the bottom cavity, each configured to receive another sampling medium having a respective sample collection area. A barrier is disposed between the bottom cavity and other cavities including the top cavity and the one or more sampling media cavities. The top cavity and the one or more sampling media cavities are in communication with each other via a common slot extending from the top cavity to the barrier. The top cavity and the one or more sampling media cavities are configured to receive a plurality of different sampling media and to align the dispenser housing with the sample collection area of each of the different sampling media.

A bacteria sampling rod in the present disclosure comprises a rod body that has a comb teeth portion at the front end to contact with a culture dish through a user's operation similar to affixing a seal or making a rotation, catch and collect bacteria on the culture dish by the comb teeth portion, and transfer bacteria into a test vessel in which the bacteria solution is diluted for final analysis at a drug sensitivity test in an analyzer. The bacteria sampling rod can be installed on an automated machine properly for a full-automatic standardized operation as well as improved working performance and quality; the bacteria sampling rod with the advantage of an elastic buffering effect is free from the risk of a culture dish punctured during bacteria collection.

The implementations described herein generally relate to 30 nm in-line liquid particle count testing equipment which analyses and cleans semiconductor processing equipment. More specifically, the implementations described relate to a system for diluting, analyzing, and modifying fluids to enable the observation of the contents of the fluids. A dilution sampling tool is coupled with a liquid particle detector for reading the contents of an extraction solution containing particles from semiconductor processing equipment, such as a liner, a shield, a faceplate, or a showerhead, in a cleaning tank. As such, accurate liquid particle readings may be had which reduce oversaturation of the particle detector.
