Abstract
An automated slide stainer with slides mounted in a horizontal position on a rotary carousel. Reagents and rinse liquids are automatically dispensed onto tissue sections or cells mounted on slides for the purpose of performing chemical or immunohistochemical stains. The rinse liquids are removed by an aspiration head connected to a source of vacuum. Individual slides or groups of slides are supported on flat heating stations for heating to individual temperatures. Temperature control electronics on the carousel are controlled by a user interface off of the carousel.
Claims13
A microscope slide stainer, comprising:
- a moving platform adapted to support a plurality of microscope slides bearing biologic samples;
- a plurality of heating elements, each heating at least one slide, the heating elements heating the slides to different temperatures;
- electronic circuitry that supplies variable amounts of electrical power to said heating elements, said electronic circuitry being mounted on the moving platform;
- and
- a user interface through which desired temperatures for microscope slides are specified, said user interface being mounted off of the moving platform and communicating data to said electronic circuitry on the moving platform to cause said electronic circuitry on the moving platform to supply electrical power to said heating elements to heat said heating elements to said desired temperatures.
A microscope slide stainer, comprising:
- a plurality of microscope slides bearing biologic samples, positioned on a moving platform;
- a plurality of heating elements on the moving platform, each element heating at least one slide, and at least one being heated to a temperature distinct from the temperatures of other heating elements;
- electronic circuitry that regulates electrical power to said heating elements, said electronic circuitry being mounted on the moving platform;
- a user interface through which desired temperatures for microscope slides is specified, said user interface being mounted off of the moving platform and said user interface comprising electronic circuitry which communicates data to the electronic circuitry on the moving platform, causing said electronic circuitry on the moving platform to supply electrical power to said heating elements to attain said desired temperature;
- and,
- a group of conductors for providing an electrical connection between said electronic circuitry on the moving platform and the user interface, the number of conductors in said group of conductors being less than the number of heater elements.
An automated device for preparation or incubation of biologic samples, comprising:
- a moving platform adapted to support a plurality of biologic samples;
- a plurality of heaters positioned on the moving platform so as to provide heat to one or more samples;
- a processor that specifies the desired temperatures for the heaters, said processor being mounted off of the moving platform;
- independent heating control capable of heating the heaters to different temperatures, said heating control comprising:
- electronic circuitry mounted on the moving platform supplying electrical power to at least one heater;
- and
- a data communication link between the processor and said electronic circuitry mounted on the moving platform, through which said electronic circuitry receives data from the processor to cause said electronic circuitry to provide an appropriate amount of electrical power to each of said heaters to heat the heaters to the processor-specified temperatures.
A microscope slide stainer, comprising:
- a moving platform adapted to support a plurality of microscope slides bearing biological samples;
- a plurality of heating means, each for heating at least one slide, each of the heating means having the capability of heating to different temperatures;
- electronic circuitry means for regulating electric power to the heating means, said electronic circuitry means being mounted on the moving platform;
- and
- user interface means in communication with the electronic circuitry means for specifying a desired temperature for each microscope slide, said user interface means being mounted off of the moving platform and communicating data to the electronic circuitry on the moving platform to regulate the electrical power to the heating means.
