Technical Field
[0001] The utility model relates to the technical field of EP pipes, in particular to a multifunctional EP pipe. Background Art
[0002] "EP tubes" usually refer to Eppendorf tubes, which are small plastic centrifuge tubes. Eppendorf is the name of a German brand that specializes in the production of laboratory equipment and consumables, including microcentrifuge tubes. Since Eppendorf brand products are very common and popular in laboratories, "Eppendorf tubes" or simply "EP tubes" have become a general term for this type of microcentrifuge tubes. EP tubes are commonly used to store, mix, centrifuge and transport micro-liquid samples such as DNA, RNA, proteins and other biomolecules. They usually have a threaded cap to ensure a tight seal to prevent sample leakage or contamination. The volume of EP tubes usually ranges from 1.5 ml to 2 ml, but there are also other sizes such as 0.5 ml, 0.2 ml and smaller micro tubes. These tubes are usually made of polypropylene (PP) and have good chemical resistance and biocompatibility, making them suitable for a variety of laboratory procedures. They can store samples at low temperatures and can also withstand high-speed centrifugation. EP tubes are an indispensable tool in modern molecular biology, biochemistry and clinical laboratories.
