The purpose of the pipette workstation is to determine all steps in the experimental process - from initial sample separation to subsequent data generation, which also includes all pre experimental preparations, such as the preparation of buffer solutions and reaction mixtures. The next step is to determine how much error is allowed in the experiment so that it does not have a significant impact on producing good data. Some applications and steps are more sensitive to errors during the experimental process than others. For example, all experiments involving amplification, such as qPCR, may be highly sensitive to errors, while simple buffer preparation steps may result in improper selection of pipettes and pipettes, as well as incorrect pipette techniques, which may be the main sources of experimental errors. Any experiment that requires continuous dilution of the standard substance to form a standard curve may be affected by poor pipette systems. Here are some precautions for selecting the suction head of a pipette workstation:
The suction head is usually made of polypropylene. Although it is inert, the potential factors of polypropylene should be considered. Different polypropylene materials determine some specific requirements in the production process, and other additives in the production process can also affect the production process. Some of these additives may leach from the suction head and affect the experimental results. To address this issue, it is recommended to purchase suction cups that do not contain dissolved substances to ensure that the supplier provides written evidence of sensitivity testing for all dissolved substances and pollutants. Pollutants include DNA and heat sources. If the manufacturing and packaging processes are not carried out in a clean room environment, these pollutants are likely to exist. There are many consumables forming and packaging facilities and equipment that are not well controlled. A good product manufacturing process should ensure that all workers wear clean work clothes, hats, masks, and gloves. Air should be filtered to avoid contamination caused by hair or insects. Material testing certificates should describe the testing process and sensitivity. Certificates that only claim that the product does not contain specific pollutants but do not provide testing methods or sensitivity will not provide any information and quality assurance.
The liquid transfer workstation is an automatic liquid processing platform system that can replace traditional liquid transfer tools, automatically complete high-precision liquid processing tasks such as gradient dilution, liquid transfer, and liquid merging, and can be combined with detection instruments to achieve accurate detection of targets. The fully automated operation process of the fully automated liquid transfer workstation not only frees laboratory staff from complex experimental operations, effectively reduces human errors, improves experimental repeatability, and reduces costs, but also enables process control and traceability. It can be widely used in biotechnology, DNA plasmid purification, drug screening, ELISA reaction, PCR pretreatment, DNA sequencing processing, clinical trial sample processing, and high-throughput sample analysis in blood station systems.
