For example, two Model 1 Ni skimmers with 0.9 mm orifices would be priced at $598.50 each after applying the quantity discount noted below, plus $90, for a total of $1,287 (see Pricing Grid). Smaller orifice sizes are also available; please inquire regarding prices. All other Ni skimmers (i.e., other than Model 1 and 2 skimmers) and all Cu skimmers are priced off the same base price grid but with a $130 set up charge per model ordered.

Large Orifice Sizes

Some skimmers can be produced with large orifice sizes, >3.0 mm. However, we are surcharged $175 per skimmer by the machine shop for such work, which we pass along. Customers should also be aware that obtaining greater orifice size is obtained by removing more of the cone and, therefore, reducing the rigidity of the resultant skimmer.

Other Models - Please email or call to determine availability and production lead time.

Other model skimmers are available by special order. Please click here for dimensions. Add $130 per Ni or Cu skimmer model ordered at the same time to the Model 1 and Model 2 stock orifice prices listed above. 

OEM Replacement Skimmers

Beam Dynamics can supply replacements for OEM equipment skimmers and maintains inventory for certain sizes. Please inquire as to availability; skimmer prices are the same as for "Other Models" above.

New Custom Skimmers - Please email or call to determine availability.

New custom skimmer designs can also be produced. There is a one-time-only tooling charge of $650 for fabricating a custom mandrel according to the geometry and dimensions supplied. The new mandrel will remain the property of Beam Dynamics, Inc. Skimmer prices are usually the same as for "Other Models" above but may vary depending on the difficulty of the design.

Gold or Rhodium Plating

For extra protection against corrosive gases, both nickel and copper skimmers may be ordered with gold or rhodium plating. The charge is $125 per skimmer.

Double Thick Skimmers

Skimmers made with a double wall thickness may also be useful for additional protection against corrosive gases, particularly when combined with gold, rhodium or chromium plating, or for higher than normal pressures. The charge is $100 per skimmer for double wall thickness.

5% for orders of 2 to 4 skimmers.
