The improvement of specimen quality for microbial analysis is addressed by the present invention which discloses a chemical composition for use in a method and apparatus for transporting a specimen suspected to contain microorganisms of interest to a laboratory for analysis and improved methods of analysis. A device and method for taking, storing, and preserving fluid samples is disclosed comprising a container and a composition designed to maintain the level of microorganisms present in a speci...

A sample-taking vessel 10 for pasty sample material, especially faeces, to be distributed in suspension fluid comprises a sample-taking cup 12 fitted on a vessel lid 14 and open towards the vessel bottom. The vessel bottom is formed with an elevation 28 which is shaped complementarily to the sample-taking cup 12. The cup wall 42 is provided at least in zones with sieve openings 44 out of which the sample material is forced and finely distributed in the suspension fluid 46 in the closing of the s...

A specimen testing element, a specimen information obtaining method and a specimen testing apparatus is used to obtain information on a specimen by utilizing a specific phenomenon attributable to wavelength selectivity, resonance characteristics and so on. The specimen testing element obtains information on a specimen by utilizing a change in the propagation state of an electromagnetic wave propagating through a transmission path due to the existence of a specimen. A plurality of holding portion...

A specimen stirring device has a stirring impeller on a rotating shaft enclosed in a pipe having one or more side holes in a central portion thereof and a nozzle portion at its end and by rotation of the stirring impeller can create a circulating flow of specimen liquid flowing out of the pipe through the nozzle portion, upward along the outside of the pipe and back into the pipe through the side holes and thereby efficiently stir a specimen liquid in a specimen container even if the specimen co...

A method and device for the calibration of microscope slides for use in accurate and repeatable position location and relocation of specific areas of a specimen on the slide, particularly with use of computer correlated location of specimen events. Deviation from orthogonality of a specimen holder positioned on a stage (relative to movement of the microscope slide stage) is determined and compensated for by means of a rectangular calibration slide having a predetermined fixed length diagonal, an...

There is disclosed a method of efficiently rotating a specimen without hindrance to observation of the specimen. A specimen holder having a holder body and a specimen-holding member is used. The holder body has a hole in which a step surface is formed. The specimen-holding member is supported from the step surface in the hole of the holder body and positioned within the hole. Arc-shaped slots are formed in the step surface. The specimen-holding member has an opening that accommodates the specime...

When a desired portion is separated from an integrated circuit chip or a semiconductor wafer, the portion is separated without dividing the chip or the wafer, so that the separated specimen can be moved to a desired position, and the separated specimen can be set to a desired attitude. Therefore, various analyses on the specimen through TEM, SEM, SIMS and so on can be carried out. A minute piece of specimen is cut and separated from the substrate of a specimen by use of a three-dimensional minut...

A container for liquid medical specimens such as urine specimens includes a container with a wide mouth opening for facilitating deposition of a urine sample, a removable cap for closing the mouth opening and an impermeable sheet liner under the cap for making a fluid tight seal with the rim. The liner is rupturable with the blunt tip of a laboratory pipette inserted through a small hole in the cap for drawing a sample of a urine specimen without removing the cap of the container. The hole in th...

The present invention an in vitro fertilization system for the receipt and treatment of an egg comprising a housing having a receiving chamber for the receipt of an egg. The system includes a holding chamber for nesting of the egg within the receiving chamber, and an apparatus for permitting treatment of the egg while the egg is held in the holding chamber. An arrangement is disposed in the housing to permit the egg in the holding chamber to be viewed non-microscopically.

A urine specimen cup with a cup portion and a lid portion mountable on the cup portion in a sealing relationship. The lid portion has walls defining an aperture therethrough and a flexible tab is mounted on the lid portion to cover the aperture and also extend over the rim of the lid portion to engage the cup portion. The first section of the tab which overlies the aperture is provided with a resealable adhesive to allow repeated lifting of the first section to provide access to the urine specim...
