PerkinElmer 500 µL Stainless Steel Sample Loop for Models 7125/7010 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: 0.76 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.
