Abstract
A compact slide spinner is disclosed. In the preferred embodiment, the compact slide spinner is used to prepare smears for microscopic evaluation. The spinner incorporates a disposable or reusable slide holder which encases a portion of a slide onto which the material to be smeared is placed. The holder containing the slide is then accelerated by spinning. Specimen fluid not adhering to the slide is contained within the slide holder which is discarded following preparation of the smear. Using this low-cost device, a uniform quality smear is quickly and easily prepared, while reducing the risk that laboratory personnel will be exposed to aerosol borne contagions.
Claims14
A device for preparing a thin film from a fluid specimen placed upon a substrate comprising:
- an enclosure for receiving said substrate and covering said fluid specimen during preparation of said thin film, said enclosure including a top, a bottom, and a plurality of sides joining said top to said bottom, at least one of said sides including an opening to receive at least a portion of said substrate therethrough, said top covering said fluid specimen on said substrate;
- and
- a spinner for spinning said enclosure and said substrate received therewithin.
An enclosure for use in preparing thin films of a fluid specimen on a microscope slide, comprising:
- a top;
- a bottom;
- and
- a plurality of sides joining said top to said bottom, at least one of said sides including an opening to receive at least a portion of said microscope slide therethrough, said top covering said fluid specimen on said microscope slide;
- and
- means for collecting excess specimen from said microscope slide during spinning.
An enclosure for preparing a thin film on a substrate utilizing a fluid specimen to prepare said thin film, said enclosure positionable on a mounting platform coupled to a spinner, said mounting platform having a plurality of mounting posts for retaining said enclosure thereon, said enclosure comprising:
- a disposable sheath having an open end, a closed end, an aperture for admitting said fluid specimen into said disposable sheath, and a plurality of apertures cooperative with said plurality of mounting posts for positioning said sheath upon said mounting platform;
- means for receiving said substrate through said open end and for positioning said substrate in said sheath;
- means for collecting excess specimen from said substrate during spinning.
