Classification of laboratory pipette tips
The pipette tip is designed to reduce the residual adsorption of the sample during the pipette pipetting process. It can be used with the pipette as a laboratory consumable. Generally, it can be divided into: standard tip, filter tip, Low adsorption tips, automatic workstation pipette tips, wide mouth pipette tips. 1. Standard tip Standard pipette tips (ie universal pipette tips) are the most widely used pipette tips, which can be used for almost all pipetting operations, and t
The performance indicators of pipette tips include: low adsorption, filter element, tightness, force of loading and ejection, no DNase and RNase, no pyrogen pollution, etc. Regarding laboratory pipette tips, you need to know some tips, as follows: 1. Use a suitable pipette tip: In order to ensure better accuracy and precision, it is recommended that the pipetting volume be within the range of 35%-100% of the tip. 2. Installation of th
The evolution and market prospects of PCR technology
PCR (Polymerase Chain Reaction) is a biotechnology based on the principle of DNA double-strand replication to amplify specific nucleic acid samples in vitro. It can quickly copy trace amounts of nucleic acid samples to millions of times, facilitating subsequent analysis and research. The technology originated in the 1970s and 1980s. After decades of development, it has experienced the evolution of the first generation of traditional PCR, the second generation of fluorescent quantitative PCR and the third generation of digital PCR. It is used in medical screening a
How to choose suitable PCR products?
What are the uses of PCR products? The PCR plate product series are widely used in genetics, biochemistry, immunity, medicine and other fields. They are not only used in basic research such as gene isolation, cloning and nucleic acid sequence analysis, but can also be used in disease diagnosis or where there are DNA and RNA. They are mainly used in conjunction with PCR/ Experimental research such as QPCR/real-time PCR is one-time consumable in the laboratory.

How can conductive automatic pipette tips improve COVID-19 detection?
In the normalization of COVID-19, the In Vitro Diagnosis (IVD) market has exploded and grown geometrically. The liquid handling method required in the diagnosis is jointly completed by a pipette and a pipette tip, and conductive PP can be applied to pipette tips, especially in a highly automated production line. The black conductive automatic pipette tip is made of medical grade polypropylene (PP), which has good conductivity and can replace the permanent sample tip to avoid cross-contamination. After the conductive tip
Can pipette tips be autoclaved?
High-pressure steam sterilization is a relatively common method of microbial sterilization, which is suitable for the sterilization of laboratory culture media, food, metal equipment, glass, enamel, dressings and medicines. High temperature and high pressure sterilization can not only kill general bacteria, fungi and other microorganisms, but also kill spores and spores. It is the most reliable and widely used physical sterilization method. Autoclave sterilization is a kind of moist heat sterilization method. Its sterili
Talking about the role of filter tips!
Since pipette tips are commonly used consumables in the laboratory, in the previous article we also explained in detail the selection of pipette tips and the impact on the experiment, so today we will talk about why we should use filter elements. The role of suction tips and filter tips. The filter tip is an upgraded version of
How to identify the quality of the centrifuge tube?
There are many types of modern laboratory consumables. However, the most familiar and frequently used consumables may be those pipe consumables. For example, a centrifuge tube, which is a common experimental consumable in the laboratory, is mainly used in conjunction with a centrifuge, that is, the experimental liquid is placed in a centrifuge tube and then centrifuged in the centrifuge. Therefore, for the consumables used in the laboratory every day, it is very important to be able to quickly identify which centrifuge tube is of high quality or inferior quality.

Did you choose the right pipette tip?
Pipette tips are one of the commonly used experimental consumables in the laboratory. They are basically disposable and are used very frequently. For consumables such as suction tips, some experimenters often only seek low prices, but ignore their quality. In fact, the effect of the quality of the tip on the experimental effect cannot be ignored, so what impact will the inferior tip have on the test? How to choose a suitable tip? The main influences of the tip on the test are as follows: 1. PipetteTips material Generally, good tips are mostly
How to select materials for laboratory centrifuge tubes
Centrifuge tube is a common experimental consumable in the laboratory, and it is mainly used in conjunction with the centrifugal dehydrator. The liquid to be tested is packed in this, and then placed in the centrifugal dehydrator for suction filtration. According to the different materials, the whole can be divided into plastic and laminated glass. Plastic centrifuge tubes are used more, and can be divided into

Regarding the selection of pipette tips, only the insiders know the secret
A pipette can only be used with a good tip! The tip is the most important factor affecting accurate pipetting. The pipette and the tip together form a complete pipetting system. The best pipetting results are usually obtained using pipettes and tips from the same manufacturer. • Low suction tip: • Low adsorption pipette tips Compared with ordinary pipette tips, the adsorption of samples is reduced by 3-5 times. The special low-adsorption resin makes the inner surfac
1. Definition: On the basis of the appearance size of ordinary microplates (mainly 96 and 384 well plates), while keeping the length and width in line with SBS international standards, the depth of the wells is increased to achieve the purpose of increasing the volume of each well. And in order to adapt to its specific scope of use, on the one hand, it is made by changing the manufacturing materials (currently polypropylene (PP) and polystyrene x (PS)) on the one hand, and on the other hand by improving the surface treat
