Description

TECHNICAL FIELD

[0001] The utility model relates to a filter core suction head production device and belongs to the medical consumable pipette tip production technical field. BACKGROUND

[0002] In modern laboratories, accurate and reliable liquid transfer is a basic requirement for various biological, chemical and medical experiments. Pipette tips, as an important part of this process, are responsible for sucking and transferring liquids from containers. Pipette tips are disposable or reusable components installed on pipettes for sucking and releasing liquids. It is usually made of transparent plastic so that users can clearly observe the volume and state of the liquid. The design of the pipette tip ensures a tight fit with the pipette, thereby achieving accurate liquid transfer. As a key tool for laboratory liquid transfer, pipette tips are divided into four types: disposable, reusable, filter core and micro.

[0003] Among them, the filter core suction head is built-in filter core, can prevent liquid into the pipette internal, protect pipette from pollution. Its filter core is usually made of polyethylene (PE) or polyurethane (PU). Filter core suction head is mainly used for handling volatile, corrosive or high viscosity liquids to prevent liquids and gases from entering the pipette. Filter core suction head is mainly used for the use of biochemical analyzer and other equipment, and the filter core is installed in the suction head (the suction head generally includes a lower sample adding section, a middle storage section and an upper adapter section, and the diameter of the adapter section is the largest) to meet the use requirements, and the filter core suction head is loaded into a batch of storage packaging boxes for convenient transportation and taking during use. In the related art, the process of loading filter core, detection and packaging of the suction head is generally performed manually. During installation, the suction head is inserted into a rotatable turntable, and then the turntable is rotated to transfer the suction head to the next process for installing the filter core.
