An improved urine specimen cup is disclosed which is anatomically convenient and which is adapted to receive a small towelette to dry the genital area.

An improved method and apparatus for facilitating specimen handling during freezing, coating and transfer to and from the main chamber of an SEM. A unique specimen shuttle manipulable by a control rod permits transfer of a specimen between the main chamber and an auxiliary air lock chamber alternatively defined by an air lock housing and a coating apparatus housing. Either housing is removably attached to an entrance flange communicating via a gate valve assembly with the main chamber and is pro...

A method for trimming of a specimen which is to be sectioned in a microtome to locate that part of the specimen which is of interest, comprising the superimposing in a microscope of the image of a cut section on the image of the specimen surface.

A specimen holder is described for collecting and examining a specimen collected from a body. The holder includes a transparent adhesive coated foldable segment. The adhesive is used to collect the specimen and retain the back-folded segment against a flat transparent portion of the holder. Visual examination of the specimen can then be carried out directly through the transparent holder without transfer of the specimen to glass slides or the like.

The invention contemplates, for use with an inverted microscope, a specimen holder having a relatively wide range of capability for replaceably accepting and holding any one of a variety of sizes and shapes of specimens. Aside from the specific capability of accepting standard-size microscope-specimen slides, the holder can equally well and positively mount circular specimen supports of various diameters, such as Petri dishes or Erlenmeyer flasks. In one disclosed form, the release and clamp ope...

A disposable kit for collecting, holding and transporting biological specimens in a saturated medium environment. A flat elongated resilient pouch of inert material is formed with two sterile hermetically sealed compartments. A rupturable transverse closure across one of the compartments defines a sealed chamber containing a transport medium. The second compartment contains a specimen collecting swab having an elongated stem. The pouch is adapted to be opened at one end to permit the swab to be ...

A specimen culturing assembly for cultivation of a specimen simultaneously under both anaerobic and aerobic environmental conditions. This assembly is especially adapted for collecting and simultaneously culturing micro-organisms suspended in a fluid (such as, blood, milk, urine, pus, etc.). The assembly comprises an anerobic container and an aerobic container releasably locked or clamped together. A special valve and tube structure allows a laboratory technician to alternately direct the fluid ...

A cart on rollers includes a rigid cabinet portion and a foldable cabinet portion permitting the cart to be folded into a volume of less than half its normal size. The cart includes trays, shelves, and compartments for holding medical supplies used in taking blood-specimens in hospitals.

Preparing a thin-film specimen adapted for TEM (transmission electron microscopy) observation. A high-brightness pixel extraction unit extracts high-brightness pixels which form a specimen image taken by an imaging unit. The intensities becoming greater than a given threshold value as the specimen is thinned. A decision unit makes a decision as to whether the high-brightness pixels extracted by the high-brightness pixel extraction unit form a continuous sequence of pixels whose number is in exce...

A method of providing a specimen section embedded in a section of paraffin wax includes providing a mold having a cover and upper and lower portions with a body of solidified paraffin wax therein, heating the paraffin wax while in the mold until it becomes molten, removing the cover of the mold, placing a specimen in the liquid paraffin in the lower mold portion, cooling the paraffin until it becomes a hardened body, and removing the lower mold portion to provide a hardened block of paraffin sec...
