PerkinElmer 50µL Stainless Steel Sample Loop for Model 7725 Rheodyne Injectors - N9306026

50µL Stainless Steel Sample Loop for Model 7725 Rheodyne Injectors. The size designations of stainless steel loops are nominal. The actual volumes can differ from the theoretical designations because of the +/- 0.025 mm (0.001") tolerance of the metal tubing bore. Accuracy of large metal loops (1.0 mm, 0.040" bore) is about +/-5%, intermediate loops (0.5 mm, 0.020" bore) +/-10%, and small loops (0.2 mm, 0.007" bore) +/-30%. Bore: 0.51 mm. Model 7725 Injector loops are not interchangeable with loops for the Model 7125. The port angle for the 7725 is 30° whereas the port angle for the 7125 is 20°, requiring the loops to have a different shape.
