Food safety is no longer a niche concern—it’s a global mandate. With the increasing complexity of food supply chains and growing consumer awareness, accurate and efficient detection of contaminants has become critical. Among the many analytical tools available, ELISA kits (Enzyme-Linked Immunosorbent Assay) have emerged as a cornerstone technology in modern food safety testing.At Novatein Biosciences Inc., based in the heart of the greater Boston biomedical research hub, we understand the science behind safe food. With our strong foundation in protein biochemistry, immunoassays, and biomarker validation, we deliver high-quality ELISA kits, including CE-marked and FDA-cleared options, manufactured under ISO9001 standards. Here’s why ELISA remains a vital solution for today’s food safety cha...

The valve is a control component in the pipeline fluid conveying system. It is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cut-off, adjustment, throttling, check, shunt or overflow and pressure relief. Valves used for fluid control, from the simplest shut-off valve to various valves used in extremely complex automatic control systems, have a wide range of varieties and specifications. Valves for industrial pipelines.The valve can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids. From the ultra-low temperature of -269℃ to the high temperature of 1430℃. The valve control can adopt a variety of transmission methods, ...
