Thin film processing apparatuses for adjustable volume accommodation

摘要

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.

主权项

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.
