Dear sir. This product is the product dionex P/N 038009?

Part number K1250 is the vial and the filter cap together in one package. This is equivalent to Dionex part number 038141. If you want just the filter cap use part number K3250. If you want just the vial use part number K2250. If you want the vial and cap with no filter use part number K4250.
