A clamp including a first jaw member having a camming surface, a second jaw member pivotable with respect to the first jaw member, a first biasing member biasing the first and second jaw members to a first position; and a locking mechanism that includes a cam or roller for cooperating with the camming surface of the jaw member, and a second biasing member biasing the cam or roller against the camming surface to lock the first and second jaw members in a second position. An optional alignment collar can be used to align components of the filtration apparatus prior to clamping. Filtration apparatus including the clamp, and also optionally including the alignment collar, is also disclosed.

Biological sample processing system comprising an imaging unit (2) comprising a digital image processing system and at least one microscope including at least one lens (14), a sample processing station (3) comprising a handling platform (3) including a support (17) and a displacement mechanism for moving the support (17), and a sample processing unit (7) mounted on the handling platform (5). The sample processing unit (7) comprises a tissue slide holder (11) for mounting thereon a tissue slide (34) with a biological sample (36) fixed thereon and a microfluidic cartridge holder (9) for mounting a microfluidic cartridge (4) thereon. The tissue slide holder (11) is coupled to the microfluidic cartridge holder (9) via a coupling (13) allowing the microfluidic cartridge and the tissue support to be mounted and removed from the sample processing unit in an opened position, and in a closed position for the tissue support (34) to be in sealing contact with the microfluidic cartridge (4). The sample processing station comprises a plurality of said sample processing units mounted on the handling platform (5) and moveable from a position allowing mounting of the tissue slide, respectively microfluidic cartridge, or removal thereof, to a position in which the viewing window in the microfluidic cartridge holder (9) is positioned in alignment with the lens of said at least one microscope.

Disclosed are a detection method and detection system using suspension liquid biochip detection. The detection method using suspension liquid biochip comprises the following steps: an excitation step and a signal acquisition step. In the excitation step, a laser light emitted by a single laser device is used to excite a classification fluorescence of nanocrystalline fluorescent microspheres and a report fluorescence of an object to be detected; and in the signal acquisition step, fluorescence detection signals are obtained through multiple acquisition channels, respectively. In the present invention, the classification fluorescence in the nanocrystalline fluorescent microspheres and the report fluorescence in the object to be detected in a sample are excited by a single laser device, which is convenient for operation and reduces the production cost of the system, thereby reducing the detection cost.
