Description

Technical Field

[0001] This utility model relates to the technical field of automatic needle filter equipment, specifically to a base for automatic needle filter equipment. Background Technology

[0002] The base (support assembly) for automatic needle filter equipment is a mechanical structure that supports and fixes the core components of the filter device. Its design must take into account stability, sealing, automation operation requirements, and ease of maintenance.

[0003] An automated needle filtration device, published in CN 119043855 A, includes a base; a pipetting and filtration unit mounted on the base, the pipetting and filtration unit having a rotating platform with a pipetting assembly on the platform, the pipetting and filtration unit having a first station and a second station, the second station having a filtration structure that cooperates with the pipetting assembly; a first pick-and-place unit mounted on the base and located near the first station, the first pick-and-place unit having a first robotic arm and a centrifuge tube holder, the end of the first robotic arm having a first gripper, and centrifuge tubes placed on the centrifuge tube holder; and a second pick-and-place unit mounted on the base and located near the second station, the second pick-and-place unit having a second robotic arm and a sample bottle holder, the end of the second robotic arm having a second gripper, and sample bottles placed on the sample bottle holder. This invention enables fully automated operation of sample liquid needle filtration, avoiding human intervention affecting the sample liquid, and simultaneously improving the filtration efficiency of the sample liquid.

[0004] Disposable consumables are dropped into a collection bin under the countertop through a disposal port. However, some liquid remains in these consumables, increasing the cost of later recycling. Furthermore, prolonged immersion in residual liquid can cause plastics (such as syringes) to deform and stick together, affecting subsequent crushing or recycling. Therefore, a base for the automated needle filter equipment is needed to address these issues. Utility Model Content
