As a key instrument used frequently, the structural design of the pipette directly determines the effectiveness of pollution prevention and control. The 1ml laboratory gamma sterilized pipette not only strives for excellence in core components such as interfaces and sealing rings, but also builds a comprehensive sterile protection system through systematic optimization of piston components, the interior of the cavity and the shell shape, building a solid safety line for high-precision experimental operations.
The pistons of traditional pipettes mostly adopt a spliced ​​structure, and the joints and gaps between components are easy to become a hotbed for liquid residue and microbial growth. The 1ml gamma sterilized pipette uses advanced injection molding technology to make the piston into a single complete component, completely eliminating the internal splicing gaps. This structural design eliminates the possibility of liquid infiltration into the piston during the pipetting process from the root, avoiding the residual sample from being corrupted and deteriorating due to long-term retention and breeding bacteria. At the same time, the piston surface is treated with a special coating to form a low surface energy characteristic, further reducing the adhesion of the liquid, and ensuring that the piston surface is clean and residue-free after each aspiration and discharge. In operations with extremely high requirements for aseptic properties, such as cell culture fluid transfer, this design can effectively prevent microorganisms from entering the sample with the piston movement, ensuring the purity of the experimental materials.
The mirror polishing treatment inside the cavity optimizes aseptic performance from a fluid dynamics perspective. The nano-level polishing process is used to control the surface roughness of the cavity to an extremely low level, forming a smooth inner wall that is almost mirror-like. This smooth surface significantly reduces the friction between the liquid and the wall, making it easier for the liquid to form a stable laminar state when flowing in the cavity, reducing liquid splashing and wall hanging caused by turbulence. When transferring viscous serum or biological samples containing tiny particles, the mirror inner wall can ensure that the liquid passes through the cavity quickly and evenly to avoid sample residue. Residual samples may not only affect the subsequent pipetting accuracy, but also easily form a breeding ground for microorganisms in the cavity. By reducing the risk of wall hanging, the 1ml gamma sterilized pipette effectively reduces the possibility of sample cross-contamination and ensures that each pipetting operation is completed in a clean environment.
The shell design also reflects the systematic consideration of sterility protection. Abandoning the grooves and sharp angles in traditional designs that are prone to dust accumulation, streamlined curved surfaces and flat surfaces are adopted to minimize the attachment points of dust and microorganisms. This morphological design not only makes it easier for experimenters to clean and disinfect before and after use, but also reduces the risk of external contaminants staying on the surface of the pipette for a long time. The shell material is made of chemically resistant medical-grade engineering plastics and is anti-statically treated to prevent dust particles from being adsorbed by static electricity. In the complex operating environment of the laboratory, even if the pipette is temporarily placed on the desktop or laboratory bench, the flat and smooth shell can effectively resist microbial contamination in the environment. In addition, the connection between the shell and the internal components adopts a seamless transition design to avoid the formation of dead corners where dirt and grime are hidden, ensuring that the overall structure meets the aseptic operation specifications.
The strong penetration of gamma rays ensures that every detail of the integrated piston, mirror cavity and special shell can be thoroughly sterilized without damaging the material properties. The deep integration of this sterilization method and structural design makes the pipette in a highly sterile state when it leaves the factory, and its own structure can continue to maintain this sterile advantage during subsequent use. Whether it is gene editing experiments in basic scientific research or pathogen detection in clinical diagnosis, the pipette can effectively block the contamination path through the synergistic effect of the overall structure.
The 1ml laboratory gamma sterilized pipette takes the overall structural design as the core, deeply integrating material science, engineering and life science experimental needs. From the process innovation of the piston assembly, to the fluid optimization inside the cavity, to the anti-pollution design of the shell shape, every detail serves the goal of sterility assurance.
