Apparatus to convert a single-mount SEM microscope stage into a multi-mount SEM microscope stage. The apparatus interfits onto the conventional center-aperture SEM microscope stage, and provides a mounting face having apertures for multiple-specimen mounts. The device is able to provide top or side views of the specimen with only a 45.degree. rotation of the microscope stage from its starting point.

A specimen kit for collection, preservation and dispatch of smear specimens collected on a glass slide makes use of a single sheet of package material having short fold-over panels at opposite end edges and long fold-over overlapping panels at the side edges, in this way to form a relatively long flat package. Transversely extending lines of perforations make possible separating the long flat package into one relatively shorter reusable package with opposite end panels and a throw away sheet. On...

A control system for a particle detector for detecting particles of blood components in an electrolyte employs sets of cams mounted on one-way clutches, which are positioned on a shaft of a motor. When the shaft is rotated by the motor in a clockwise direction, one set of cams moves together with the shaft, and when the shaft is rotated in the counterclockwise direction, another set of cams rotates in the counterclockwise direction. The rotation of cams controls movement of pistons which, togeth...

An improved test unit is provided for use in the collection and analysis of biological specimens and the like. The specimen test unit includes a swab member adapted for collection of a specimen to be tested. The test unit incorporates one or more reagents or other test fluids for delivery into contact with the specimen on the swab member. In accordance with various embodiments, the contacted specimen and fluid are then delivered through one or more porous filter members for analysis and/or to co...

This invention relates to a test specimen for generating data to provide a preliminary qualification of plastic materials for fabricated parts without requiring prototype development. The test specimen disclosed has two plates which are designed to be joined in various ways and the resulting joints evaluated. The plates are provided with latches and tabs to test mechanical locking. The test specimens are also provided with a series of grooves, a raised section, posts, holes and self-tapping lugs...

The present invention discloses a device, kit and method for concurrent sampling of a fecal specimen and temperature measurement from a single rectal penetration. The device comprises an elongated, rigid, cylindrical sleeve with a partially cutaway distal end to form a scoop and a thermometer optionally inserted into a bore in the sleeve. The kit includes, in addition to the sleeve, a vial adapted to receive the sleeve therein for permitting analysis of the fecal specimen in the sampling scoop i...

When processing a specimen by a plurality of specimen processing devices arranged along a transportation line, a specimen tag on which a coded group code representing a combination including at least one processing item is adhered on the specimen container. A plurality of such specimen containers are mounted on a specimen support bearing a specific carrier tag. Prior to transporting the specimen support, the specimen tags and the carrier tag are read, and based on the read result, an information...

The invention is directed to a stereomicroscope having a specimen changer which is at least so configured that it is rotatable about a column of a column stand and the specimen changer has receptacles for specimens arranged on a circular path passing through the viewing beam path. The specimen changer includes an inner stationary part and an annular-shaped outer part which includes the receptacles for the specimens. The specimen receptacles have a diameter suitable for receiving commercially ava...

A biological specimen cassette adapted to be installed with similarly constructed cassettes as a package in a cassette dispenser from which cassettes are thereafter dispensed individually comprises a channel formed in at least one of its walls to receive a connecting element, such as band, string or wire, which, when engaged to all cassettes, form a collective stacked arrangement of cassettes which is insertable into the cassette dispenser. Once received in the dispenser, the connecting element ...

A disposable specimen cup and bracket for holding the same comprising a bracket with bendable arms designed to fit over the rim of a toilet bowl and extending into the toilet bowl and having a hole for receiving a sample cup which funnels fluids to the center and is designed to sit upright on a stand or within the bracket hole when the bracket is within the toilet bowl.
