Some knowledge points of suction head

Generally, the pipette tip is made of pure PP without plasticizer and release agent, otherwise the dissolved matter will affect the experimental results. High dimensional accuracy, otherwise it will lead to poor sealing consistency; The inner wall is required to be smooth and free of flow marks, and the front end is required to be free of notches and burrs, otherwise the drainage will be inaccurate; It is clean and free of biological pollution, and it is required to be manufactured in an ultra clean environment. Although most standard pipette tips do not require conductivity, tips used for liquid treatment in drug detection systems need not only conductivity, but also excellent physical properties and chemical resistance. In addition, as the pipette tip becomes longer and larger in design, the conductive compound used to make the tip needs to flow more easily to accommodate a narrower processing window. The pipette suction head is mainly packaged in bags and boxes. In the relatively mature market, boxed products account for the majority; In the Chinese market, bagging is the mainstream at present - the main reason is that bagging is cheap. Bagging is to put the suction heads in plastic bags with 500 or 1000 suction heads in each bag (the number of suction heads in each bag will be much smaller if the number of suction heads is large). Most customers will buy a bag of suction heads, and then manually put them into the suction head box, and then sterilize them with a high-pressure steam sterilizer. The adaptability of pipette tip is a problem that users are more and more concerned about. Why? Because not all suction heads can be used on the pipette of the corresponding range of any brand, customers must pay attention to the adaptability of the suction head when purchasing the suction head. We can discuss the adaptability of the desorption head from the following aspects: 1. Specificity of pipette tip: some pipettes of some brands can only use their own standard pipette tip, while others cannot. 2. Adaptability of suction head: it is common that a pipette can use multiple suction heads, but the pipetting effect is different after installing different suction heads. 3. The range of the suction head and the pipette shall be compatible: generally, the volume of the suction head shall be greater than or equal to the Zui range of the pipette. For example, the 200L suction head can be used for pipettes with ranges of 20L, 100L and 200L; The above are some knowledge points about the suction head. I hope I can help you.
