Biological sample analytical instrument
A method for processing a biological material sample includes dispensing a sample into wells of an array tape from a sample plate, dispensing a reagent into the wells of the array tape from a reagent plate, and sealing the sample and the reagent in the array tape. The method further includes cooling the array tape and detecting biological material in the wells of the array tape.
1. An apparatus for processing a biological material sample, the apparatus comprising:
a dispensing system configured and arranged for dispensing a sample and a reagent into a matrix of wells of a tape;
a sealing system configured and arranged for sealing the sample and the reagent in the tape, the sealing system comprising:
a sealing mechanism located adjacent a cooling system,
the cooling system positioned directly below the sealing mechanism on an opposite side of the tape from the sealing mechanism, the cooling system, configured and arranged for cooling the sample as the tape is sealed by the sealing mechanism; and
an amplification and detection system for detecting biological material in the matrix of wells of the tape; and
wherein the cooling system comprises a Peltier plate mounted directly to the underside of a groove plate, the Peltier plate configured and arranged to supply cooling via conduction and convection as the tape moves over the groove plate and while the tape is stopped.
2. An apparatus for processing a biological material sample, the apparatus comprising:
a dispensing system configured and arranged for dispensing a sample and a reagent into a matrix of wells of a tape;
a sealing system configured and arranged for sealing the sample and the reagent in the tape, the sealing system comprising:
a sealing mechanism located adjacent a cooling system,
the cooling system positioned directly below the sealing mechanism on an opposite side of the tape from the sealing mechanism, the cooling system, configured and arranged for cooling the sample as the tape is sealed by the sealing mechanism; and
wherein the sealing mechanism comprises a weighted roller, wherein thermal transfer between the tape and the cooling system occurs when the weighted roller pushes the tape to a groove plate to seal the tape in preparation for incubation.
3. The apparatus of claim 2 , wherein the sealing system further comprises a pressure plate configured to provide additional pressure to the tape and improve thermal conduction between the tape and the cooling system.
4. The apparatus of claim 3 , wherein the pressure plate comprises rollers, the rollers configured to allow the tape to move freely under the pressure plate while maintaining pressure at an interface including the tape and groove plate.
5. The apparatus of claim 3 , wherein the pressure plate is configured to be adapted to receive a mixer attachment, the mixer attachment including an electrical motor and eccentric cam configured to vibrate the tape providing mixing enhancement within the wells of the tape.
