Selecting the right reaction plates for PCR consumables involves various considerations tailored to specific laboratory needs. PCR plates typically come in different formats, including 96-well, 384-well, and alternative options like 24-well and 48-well formats. The choice of PCR plates is influenced by factors such as the type of PCR instrument used and the nature of the application. Skirt Design: The skirt of a PCR plate, referring to the material surrounding the plate, plays a crucial role in...

To complete the automatic packaging of the pipette tips, it is necessary to analyze the process requirements for the automatic packaging. First, it is necessary to complete the automatic feeding of the pipette tip and the box, and then insert the pipette tip into the hole in the box to complete the action. Figure 1 shows the flow chart of the process of the pipette tip box, which is as follows: (1) Disperse the accumulated pipette tips. (2) The pipette tip should be kept with the big head facing...

1.1 The analysis of packaging of pipette tips There are three main types of pipette tips on the market: bagged, boxed and refillable pipette tips. Among them, bagged tips are mainly used in China, and boxed tips and refill tips account for a small share. Bagged tips are mainly used due to both price and technology. For bagged tips, as shown in Figure 1-1(a), the pipette tips are scattered in plastic ziplock bags. Usually, each bag contains 500 or 1000 tips. For some pipette tips with high volume,...

Under the severe situation of the coronavirus, it is an effective measure to prevent cross-infection in the hospital while saving the patient's life as a medical worker. Front-line medical staff need to wear protective tools such as medical protective masks (N95) and goggles. In clinical practice, it is found that the goggles are fogged due to the gas exhaled by the medical staff, resulting in reduced visibility of the goggles and blocked vision. There are different ways to solve this problem....
