Frequently Asked Questions About Your Ultra High Vacuum System

No. Viewports require specific cleaning procedures based on viewport type. Use MPF's UHV viewport cleaning guidance rather than soap and water.

No. During low-vacuum pump down, the system can pass through a glow-discharge region with an ionized environment. Applying voltage during this phase can create an electrical short.

Yes. MPF provides information about its testing and quality-control capabilities, including pressure testing, magnetic permeability testing, and related equipment.

Yes. MPF carries ISO 9001:2015 certification, meaning its vacuum vessel component manufacturing processes meet stringent quality-management standards.

MPF uses a helium leak detector to test for leaks at less than 1 x 10^-9 atm cc/sec. Verification up to 1 x 10^-10 may also be available by request.

Yes. MPF can attach custom parts to both standard and specialty assemblies, including custom flanges, mounts, and plates.

Mounting options include ISO, KF/QF, wire-seal, ASA/ANSI, and JIS flanges for ultra-high-vacuum chambers.

Yes. MPF technical specialists help customers design custom UHV systems, custom components, and bespoke ultra-high-vacuum assemblies. MPF also provides quotes for custom UHV components and systems.

MPF uses ceramic-to-metal sealing technology for high-vacuum assemblies and verifies hermetic performance through helium leak detection.

Ceramic-to-metal sealing provides mechanical strength and electrical insulation in harsh environments and extreme temperatures.

Standard MPF electric isolators, also known as high-voltage breaks, provide voltage standoff from 5KV to 60KV. Custom isolators can be manufactured for applications requiring up to 225,000 volts of standoff.

Each UHV isolator is built as a metal adapter hermetically bonded to alumina ceramic for voltage standoff at each end.

MPF offers power feedthroughs across a wide voltage range, from 500 volts up to 100KV. These high-voltage feedthroughs are used in applications including healthcare and food safety, and are available in different configurations and ceramic lengths.

MPF viewports use UV and EUV grade fused silica and sapphire. Available coating options include anti-reflection, ITO, high-reflective, dielectric, enhanced metal, partial reflector, low-loss, and low-absorption coatings.

No. Online checkout cannot use a freight collect number. Contact Customer Service to place the order and provide freight collect details.

Create an account before ordering and upload your Tax Exemption Certificate. An MPF employee will review and approve the certificate, which may take up to 24 hours.

If a credit card will not process online, contact Customer Service for help placing the order.

Yes. Contact Customer Service to request a refund for the sales tax charge.

Yes, if the order has not already shipped. Contact Customer Service to request an upgraded shipping method. Additional shipping charges will apply.

Place the order, then contact Customer Service to let MPF know the certificate was uploaded. After approval, sales tax can be refunded to the card used for purchase.

Yes. MPF uses the Order Number to identify the order.

Yes. MPF vacuum vessel components can be purchased through the website and shipped worldwide.

Yes. MPF uses an F.O.B. Origin shipping arrangement. Once products are loaded onto the carrier at MPF's facility, responsibility and shipping risk transfer to the buyer.

Standard parts typically ship within a few weeks. Customers can request current lead-time information by email.
