연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

An apparatus can be used to apply and remove fluid substances for processing biological samples. The fluid substances can be delivered between a first substrate and a second substrate. One substrate carries a specimen. A layer of the fluid substance is retained in a gap defined by the first and second substrates. One substrate is moved with respect to the second substrate to disperse the fluid substance in the gap.

1. An automated slide processing station, comprising: a first platen assembly having a curved portion; a drive mechanism configured to move the first platen assembly from a standby position to a processing position, a liquid dispensing assembly for dispensing a liquid; and a second platen assembly comprising a slide positioning device, said slide positioning device comprising a slide retaining device, the slide positioning device operable to position a slide retained by the slide retaining device proximate to the first platen assembly, the first platen assembly and second platen assembly being configured to cause a longitudinal or transverse rolling movement of the curved portion of the first platen assembly relative to the second platen assembly retained slide to create a varying height gap between the slide and the curved portion sufficient to apply a liquid to a sample on the slide, wherein the first platen assembly includes a holder and a cover removably coupled to the holder, the cover defines at least a portion of the curved portion. 2. The automated slide processing station of claim 1, wherein the first platen assembly includes a specimen facing surface that comprises a semi-compliant material that is more compliant than the slide. 3. The automated slide processing station of claim 1, wherein the first platen assembly includes a specimen facing surface for contacting the liquid in the varying height gap, the specimen facing surface comprises a rigid material. 4. An automated slide processing station, comprising: a first platen assembly having a curved portion; a drive mechanism configured to move the first platen assembly from a standby position to a processing position; a liquid dispensing assembly for dispensing a liquid; and a second platen assembly comprising a slide positioning device, said slide positioning device comprising a slide retaining device, the slide positioning device operable to position a slide retained by the slide retaining device proximate to the first platen assembly, the first platen assembly and second platen assembly being configured to cause a longitudinal or transverse rolling movement of the curved portion of the first platen assembly relative to the second platen assembly retained slide to create a varying height gap between the slide and the curved portion sufficient to apply a liquid to a sample on the slide, wherein the first platen assembly includes a holder and a cover removably coupled to the holder, the cover has a relatively compliant specimen facing surface for contacting the liquid in the varying height gap, and wherein the holder is relatively rigid. 5. The automated slide processing station of claim 4, wherein at least one of the first platen assembly and the second platen assembly includes at least one thermal element configured to receive electrical energy and to generate heat using the electrical energy. 6. The automated slide processing station of claim 4, wherein the liquid dispensing assembly includes at least one thermal element configured to receive electrical energy and to generate heat using the electrical energy to heat the liquid. 7. The automated slide processing station of claim 4, wherein the liquid dispensing assembly is configured to dispense the liquid from a pipette onto at least one of the slide and the curved portion and/or into the varying height gap. 8. The automated slide processing station of claim 4, wherein the liquid dispensing assembly includes a dispensing unit coupled to the second platen assembly, the dispensing unit has an outlet port positioned to dispense a liquid between the curved portion and the slide held by the slide positioning device. 9. The automated slide processing station of claim 4, wherein the slide retaining device is movable between an open position for receiving the slide and a gripping position for gripping the slide. 10. The automated slide processing station of claim 4, wherein the slide retaining device includes a vacuum chuck for holding the slide. 11. The automated slide processing station of claim 4, wherein the liquid dispensing assembly includes an outlet port positioned to deliver liquid between the slide and the cover to at least partially fill the varying height gap. 12. The automated slide processing station of claim 4, wherein at least one of the first and second platen assemblies includes a gapping element dimensioned to define the varying height gap between the slide and the curved portion. 13. The automated slide processing station of claim 4, wherein the first platen assembly includes a liquid application region and a plurality of discrete gapping elements positioned outside of the liquid application region and spaced apart from one another along a length of the liquid application region, the plurality of discrete gapping elements are dimensioned to space the slide from the liquid application region to create the varying height gap. 14.
