ConeGuard Thread Protector, Skimmer (extended) for Agilent 7500c and 7700s

When cleaning cones that have a screw thread, it is important that the thread is not contacted by any corrosive solution. If the thread gets corroded, the cone may not seal correctly or it may bond to the base and be difficult to remove. And with Pt cones, the thread is likely to wear out before the Pt insert. The ConeGuard Thread Protector seals the thread and protects it from corrosion during the cleaning process.
