The high uniformity solenoid is used to increase uniformity over other conventional solenoids. It is possible to increase the uniformity of the solenoid by using a variety of windings of the coil and combining the windings. The external volume of the solenoid is smaller than that of an ordinary solenoid, but the uniformity is higher, which effectively reduces the total length of the solenoid. Especially suitable for longer sample measurement, the high uniformity solenoid is more convenient to use and more widely used. We are capable of customizing these products to the customer’s specifications.
