Loops are electrolytically cut and electrochemically polished to insure square, burr-free ends, then cleaned with microfiltered steam from deionized water.
Sample loops are accurately sized for each valve type. However, with small volume loops the tolerance on the ID of the tubing (± 0.001") can have a significant effect on the volume. Therefore loop volume and loop appearance may differ from batch to batch.
Loops includes two stainless steel nuts and ferrules.
