Example Embodiment

[0034] refer to Figure 1 to Figure 3 The embodiment of the manufacturing method of an overflow stop type serological pipette of the present invention will be further described.

[0035]For ease of description, spatially relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to describe how one element or feature shown in the figures is relative to another element or feature. relation. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both upper and lower positions. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative referenc...

Abstract

The invention discloses a manufacturing method of an anti-overflow type serum transfer pipette, and aims to provide a manufacturing method of an anti-overflow type serum transfer pipette, which is characterized in that high molecular weight polyethylene powder and a high molecular elastomer are mixed and sintered to form a high-waterproofness filter element, has a good blanking effect and ensures the qualification rate of the filter element. According to the key points of the technical scheme, a high-molecular elastomer is embedded into a porous structure of a filter element through a sintering process, in a dry state, the high-molecular elastomer does not expand, air passages between filter element networks keep high air permeability, after the high-molecular elastomer is in contact with water, the high-molecular elastomer rapidly expands to block the porous structure, the air passages are closed, and an aqueous solution cannot pass through; by adding the color master batch, the filter element is colored after being produced, so that the method is convenient to observe and high in practicability, and the method is suitable for the technical field of pipette manufacturing methods.

Description

technical field [0001] The present invention relates to the technical field of a pipette manufacturing method, more specifically, it relates to a method of manufacturing a stop-spill serological pipette. Background technique [0002] Serological pipettes are biological consumables for quantitative pipetting tubes and bottles, and are widely used in cell culture, bacterial culture, clinical, scientific research and other biological fields. The filter components currently used in the market are medical cotton or PET material filter cotton. This type of filter only achieves the purpose of ventilation and blocking aerosol pollution. When over-range pipetting or misuse causes liquid to splash through the filter or flow into the pipette, it will contaminate the pipette and cause serious cross-contamination. [0003] Therefore, how to improve the yield of the filter element by using filter elements of other materials and through different production processes, the formed pipette ...
