Get Free Sample of Drager Air and Flow Cytometry Tubes

Flow Cytometry Tubes produce a pressure drop so that the flow is regulated in a pipe system. There are different branded and specialized flow tubes such as the drager air flow tubes and others. The tubes are made from different material grades. One of the most used grades is the 304 austenitic stainless steel grade with 18% chromium, 8% nickel and manganese, phosphorus, sulfur and silicon. The Stainless Steel Flow Tubes range in smaller outer diameters up to 4mm. The capillary tubes are made to perform accurate fluid flows through narrow spaces for precision applications. The applications include tools, equipment and other sensitive parts in various applications.

Flow Through Capillary Tubes are available in 1/2 to 3 Inch

The Flow Cytometry Tubes are used in petroleum, oil and gas, power generation, nuclear plants and other sensitive industrial applications. There are tubes that are used in heating and cooling applications as well. The Coolant Flow Tubes are used to draw coolants through machine and engine parts. These tubes and pipes have to be strong, corrosion resistant, heat resistant and abrasion resistant. Some of the applications also present high impact risk. At these instances, the pipes need to be high impact resistant. The pipe diameters, lengths and other dimensions vary according to the customer requirements and application requirements.

Working Principle of Drager Air Flow Tubes

The tube consists of a short, straight inlet section followed by an abrupt decrease in the inside diameter of the tube. This section, called the inlet shoulder, is followed by the converging inlet cone and a diverging exit cone. The two cones are separated by a slot or gap between the two cones. The low pressure is measured at the slotted throat. The high pressure is measured at the upstream edge of the inlet shoulder.
