The life science industry is full of machinery and equipment that depend on orifice restrictors. Much like the medical industry, high levels of sanitation are required. Common devices that utilize orifice restrictors include:
Analytical machines: Analytical machines that need to regulate the flow and pressure of gas or liquids incorporate orifice restrictors.
Bioreactors: Bioreactors are used in countless applications, including processing food, feed, pharmaceuticals, and chemicals. All of these will need to control pressure and flow to varying degrees, so they use orifice restrictors.
Gas detection: Gas detection systems need air to easily flow without causing problems related to pressure or cavitation. Many gas detection devices incorporate orifice restrictors for adequate functionality and longevity.
Flow cytometry: Flow cytometry is a sophisticated technique that provides a multi-parametric analysis of individual cells. In addition to using lasers and strategic light sources, this technology relies on orifice restrictors to control the flow of media.
Luminescence immunoassay analyzer: This device is used to detect the presence and concentration of specific substances in a sample. Common media include blood or urine. To control the flow of the medium and regulate pressure, this machinery uses orifice restrictors.
Electrophoresis: Electrophoresis is a common technique used to separate RNA, DNA, or protein molecules based on their electrical charge and size. This is achieved by moving the molecules through a gel or other type of matrix. Many electrophoresis machines use orifice restrictors to manage the flows and pressures of used media.
流量測(cè)量
Flow Measurement
節(jié)流孔可實(shí)現(xiàn)壓力管理和流量測(cè)量。這利用了伯努利原理：障礙物（節(jié)流孔）下游的壓力低于其上游的壓力。通過合理的工程設(shè)計(jì)和制造，節(jié)流孔可用于實(shí)現(xiàn)可靠的流量測(cè)量。
Orifice restrictor plates accomplish pressure management and flow measurement. This is done by utilizing the Bernoulli principle: the pressure downstream of an obstruction (the orifice restrictor) is lower than the pressure upstream of the obstruction. With the proper engineering and design, an orifice restrictor can be used to create reliable flow measurements.
