The present invention relates to an apparatus. i.e. a device, for transferring a representative sample of a liquid containing particles into a chamber for analysis, such as for example, whole anticoagulated blood. The apparatus comprises an ante-chamber configured for receiving, containing, and transferring a portion of the sample to an analysis chamber. The chambers are continuous with each other, configured to allow the capillary flow of substantially the entirety of the contents of the ante-chamber into the analysis chamber to under-fill or substantially fill the analysis chamber. The apparatus can be conveniently configured as a disposable, single-use device, such as a dipstick, for performing both sampling and analysis from a single apparatus. The apparatus is useful for providing reliable and reproducible blood and body fluid analyses.

A dipstick electrochemical sensing device (1) is disclosed, for assessing an analyte in a fluid sample (44), comprising a main body (2) provided with a reference electrode (4) and a working electrode (6, 8, 10), wherein the reference electrode (4) is located in a reference chamber (18) provided with a first port (20), while the working electrode (6, 8, 10) is located in a measurement chamber (22) provided with a second port (24), wherein the sensing device (1) is further provided with a bridge (32), connecting the reference and measurement chambers (18, 22) through corresponding interfaces (28, 30), and through which a fluid may flow, at least one interface (30) having fluid flow restricting characteristics which are pressure dependent, and wherein the measurement chamber (22) is partially delimited by a removable wall (34) so that it can be removed to open a distinct main opening through which the fluid sample can enter inside the measurement chamber (22) and contact the working electrode (6, 8, 10) for the purpose of conducting an assessment.

Disclosed herein is a packaging system for dispensing a personal care product such as a perfume. The packaging system has dual dispensing option of a dipstick and a roll-on dispenser in a single unit. The packaging system includes a reservoir, a lower cap, and an upper cap. The lower cap has a dipstick that is wetted in the reservoir. The lower cap can be unscrewed from the reservoir to expose the dipstick for use in dabbing a personal care product on skin. The lower cap also has a spherical ball that is exposed when the upper cap is unscrewed from the lower cap while the lower cap remains engaged with the reservoir section. When the packaging system is turned on its side or upside down, the liquid personal care product wets the spherical ball, and the ball can be used for roll-on application of the personal care product.

This utility model relates to the field of three-stage sampling operation technology for oil storage tanks, and particularly to an oil tank sampling and purification device. It aims to overcome the technical problems of existing methods that require two people to operate the dipstick and sampling rope to control the sampling bottle, leading to difficulties in coordination and direct contact between operators and the sampling rope, which can easily cause oil spillage and contamination. This oil tank sampling and purification device uses a winding wheel to control the release length of the dipstick and a winding wheel to control the release length of the sampling rope. The operator can independently complete the sampling task by operating the winding wheel and winding wheel separately with both hands, without direct contact with the sampling bottle, thus avoiding the problem of oil spillage and contamination. This overcomes the technical problems of existing oil tank sampling methods that require two people to operate the dipstick and sampling rope to control the sampling bottle, leading to difficulties in coordination and direct contact between operators and the sampling rope, which can easily cause oil spillage and contamination.

A method for detecting a targeted nucleic acid from a deoxyribonucleic acid (DNA) sample extracted using a DNA extraction kit through DNA amplification testing comprising: (i) preparing a DNA extraction kit and a test sample; (ii) adding the test sample to the tube containing the lysis buffer, shaking and incubating to obtain a sample-containing tube; (iii) shaking the sample-containing tube, then immersing the dipstick into the sample-containing tube to obtain a sample-loaded dipstick; (iv) transferring the sample-loaded dipstick into the tube containing the wash buffer, removing excess wash buffer from the dipstick to obtain a dipstick containing the DNA from the test sample; and (v) amplifying the DNA from the dipstick containing the DNA of the test sample using a DNA amplification technique and reading the result to detect the targeted nucleic acid.
