When I place my order online, is the Order Number the same as the Purchase Order Number?
Yes. MPF uses the Order Number to identify the order.
Yes. MPF uses the Order Number to identify the order.
No. Online checkout cannot use a freight collect number. Contact Customer Service to place the order and provide freight collect details.
Yes, if the order has not already shipped. Contact Customer Service to request an upgraded shipping method. Additional shipping charges will apply.
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.
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.
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.
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.
MPF guarantees products against production defects and listed performance-data issues for 365 days after receipt. Unused standard catalog items may be returned within 365 days if they are in original packaging. Restocking fees may apply, and custom items cannot be returned.
Standard parts typically ship within a few weeks. Customers can request current lead-time information by email.
Yes. MPF vacuum vessel components can be purchased through the website and shipped worldwide.
Yes. MPF provides information about its testing and quality-control capabilities, including pressure testing, magnetic permeability testing, and related equipment.
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 carries ISO 9001:2015 certification, meaning its vacuum vessel component manufacturing processes meet stringent quality-management standards.
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.
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.
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.
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 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.
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.
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.
