Flow cytometric analysis technology plays an increasingly important role in the research of modern cell molecular biology. This analysis technology is through the rapid determination of single cell traits, combined with advanced computer analysis system, making it possible in a short time Qualitative and quantitative determination of a large number of cells. But in the past, the operation and analysis of flow cytometers required a skilled research team, and the value of this equipment was very high-at least 100,000 US dollars, some even reached 500,000 US dollars, which is not for many laboratories. Easy to afford.
In recent years, some mainstream biotechnology companies have successively introduced new flow cytometers, making this technology easier to operate and more affordable. Most of the current flow cytometry analysis system settings are automated, and related kits have also been verified many times, simplifying operations and lowering the entry threshold. Some large companies, such as Sony and BD, have increased R & D efforts and developed flow cytometers under $ 100,000. The customer base has shifted from a central laboratory to individual researchers.
However, these new types of flow cytometers are not meant to be used immediately. Users must understand what this technology can and cannot do before purchasing. Sometimes, after purchasing a flow cytometer in the laboratory, it is not applicable. This is a waste of resources and time, so it is very important to understand what you need and the advantages and disadvantages of different instruments. The following are a few new types of flow cytometers that are currently in the market. By analyzing their advantages and disadvantages, you may be more purposeful when purchasing.
PP plastic, also known as polypropylene plastic, is another fine resin varieties, following the development of nylon, which is a semi-crystalline materials, the advantage is obvious, with excellent mechanical properties and heat resistance, with a high not hydrophilic sex, almost non-absorbent. The disadvantage is poor low temperature impact resistance, easier to aging. However, for comparison PE plastic having a higher melting point.
PE plastic is polyethylene plastic, its corrosion resistance and electrical insulation are very strong. Rigid hardness and strength are relatively high, and the same PP plastic, it also very small water absorption.
Polycarbonate (referred PC) is a polymer molecular chain containing a carbonate group, an ester group according to the structure can be divided into aliphatic, aromatic, aliphatic - aromatic and other types. Which due to the aliphatic and aliphatic - aromatic polycarbonate lower mechanical properties, thereby limiting its application in engineering terms. Currently, only the aromatic polycarbonate obtained industrial production. Due to the special nature of the polycarbonate structure, it has now become the top five fastest growing engineering plastics in general engineering plastics.
