Abstract

An apparatus including a reagent cartridge and a reaction chamber, the reagent cartridge having a reagent capsule removably positioned therein for dispensing of a reagent onto the reaction chamber. A system including a linearly translatable mounting assembly having a plurality of mounting stations dimensioned to receive at least one fluid dispensing cartridge, a linearly translatable bulk reagent dispensing assembly having a plurality of bulk reagent dispensing nozzles coupled thereto and a receiving assembly positioned beneath the mounting assembly and the bulk reagent dispensing assembly, the receiving assembly including a plurality of reaction stations. A method including determining an inventory of an automated sample processing system, downloading a processing protocol from a central controller to the automated sample processing system, operating the automated sample processing system based on the processing protocol and independently of the central controller and dispensing a reagent from the automated sample processing system.

Claims

1. An apparatus comprising:

a reagent cartridge having a reagent retaining recess and a reagent directing channel, both the reagent retaining recess and reagent directing channel in fluid communication with an outlet channel extending from a bottom of the reagent cartridge;

a reaction chamber having a platen dimensioned to receive a slide, the platen defining a substantially planar surface having a reagent drip portion for receiving a reagent dispensed from the reagent cartridge, the reaction chamber having a first fluid outlet port, a second fluid outlet port and a fluid inlet port extending through the platen, wherein the fluid inlet port is positioned between the first fluid outlet port and the second fluid outlet port; and

a support member having an upper portion and a lower portion, wherein the upper portion and the lower portion are laterally offset with respect to one another, and the upper portion is dimensioned to removably support the reagent cartridge above the reaction chamber and the lower portion is dimensioned to support the reaction chamber at an angle such that the substantially planar surface formed within the reaction chamber is tilted at a horizontal angle and a vertical angle with respect to level ground.

2. The apparatus of claim 1 wherein the reagent retaining recess is dimensioned to receive a reagent capsule having a reagent contained therein.

3. The apparatus of claim 2 wherein the reagent capsule comprises a collapsible container and a plunger dimensioned to break a seal of the container when the container is collapsed.

4. The apparatus of claim 1 further comprising:

a first identifier and a second identifier coupled to the reagent cartridge, the first identifier and the second identifier comprising information identifying a reagent contained within the reagent cartridge and wherein one of the first identifier and the second identifier is removable.

5. The apparatus of claim 1 wherein the platen is comprised of a hydrophilic material.

6. The apparatus of claim 1 wherein the platen is comprised of a metal material having at least one of an antimicrobial or a corrosion resistance property.

7. The apparatus of claim 1 wherein the substantially planar surface is formed at the horizontal angle and the horizontal angle is from 5 degrees to 15 degrees with respect to level ground.

8. The apparatus of claim 1 wherein the substantially planar surface is formed at the vertical angle and the vertical angle is from 15 degrees to 45 degrees with respect to level ground.

9. The apparatus of claim 1 further comprising at least one spacer member extending from a surface of the platen to create an uneven gap between the platen and a slide positioned on the platen.

10. The apparatus of claim 1 further comprising a bulk reagent reservoir coupled to the reaction chamber the bulk reagent reservoir in fluid communication with the reaction chamber.

11. The apparatus of claim 1 further comprising a temperature modifying assembly coupled to the platen to modify a temperature of the reaction chamber.

12. The apparatus of claim 11 wherein the temperature modifying assembly comprises a thermoelectric cooler (TEC).

13. The apparatus of claim 11 wherein the temperature modifying assembly comprises a heat sink and a fan to control a temperature of the temperature modifying assembly.

14. The apparatus of claim 11 wherein the temperature modifying assembly comprises a thermistor for monitoring a temperature of the reaction chamber.
