If you found yourself in the dark after Grace decided to stop selling chromatography consumables like graphite ferrules, vials, caps, septa, gas purifiers, and inlet liners, you no longer have to worry. The founder of GCFerrules.com has been in the chromatography market for over 40 years and spent part of that time working at Alltech. We have gone through all of our parts and cross referenced them to as many Grace and Alltech parts that we could find. You can easily search for an old Grace or Alltech part numbers by entering it in the search bar on the GCFerrules.com homepage. We will automatically pull up our equivalent. And while browsing through our selection of products, you can also see below each product a section that says "Similiar to" which lists all of the cross referenced part numbers. If you ever have trouble finding a product, please email us at firstname.lastname@example.org and we will help you find it.
