Think twice before buying from these vendors.

Latest revision as of 19:40, 4 February 2021

See Usernames for a list of logins to some of these vendors.

Also check out ThomasNet or Direct Industry for a searchable vendor list.

Don't forget about the Black List

Thanks to Stan Cotreau and the DeMille group for helping us to put this together.

Buyers guides

Ablation target preparation and testing

  • Applied Test Systems - high-end materials testing and furnaces
  • Futek - Load cells and other sensors
  • MTI Corporation - relatively inexpensive materials science research supplies (furnaces, temp. controllers, crucibles, gloveboxes, benchtop presses, diamond blade saws, ball mills, nanopowders...); equipment seems generally reliable though cheap. Technical support is of little help.
  • Renco Corporation - sells a wide variety of glovebox gloves, but they're a little laggy on responding to quote requests.
  • Sigma-Aldrich - also sells a lot of glovebox gloves and sleeves, and as a "Harvard Marketplace" company, they're very convenient and relatively cheap to order from on HCOM
  • Thermo Scientific - general lab supplies, including furnaces (Please see this note before considering buying from them, though!)

Radiation equipment

  • For radiation inspection, non-emergency cleanup, and radiation labels and waste bins, contact Ken Walker at first_last@harvard.edu.
  • Atlantic Nuclear - radiation safety: shielding, radiation meters, dosimetry
  • Ludlum Measurements - exhaustive assortment of survey meters
  • Canberra - radiation measurement and safety supplies, including radioisotope samples

Chemicals and materials

Ablation targets

Adhesives and Glues

  • EMI UV - Fancy UV curing epoxy, low expansion and UHV (Optocast 3410 Gen2)

Ceramics

Metals

See also: #Chemicals_and_materials

  • ESPI - expensive, but has everything
  • Goodfellow - metric, crazy expensive
  • Rembar- Good for Tantalum, Tungsten etc
  • Surepure Chemetals - Precious metals and wire in many sizes, cheap
  • Hagstoz - Gold and precious metals, usually cheap
  • Refining Systems - Gold and precious metals
  • Hauser and Miller - Even cheaper gold and precious metals
  • Allfoils - "UHV Aluminum Foil"
  • Sophisticated alloys
  • Parker Steel - Metric metals (not just steel). Tell Gary Bartlett that Stan sent you.
  • Copper.org Data on copper alloy compositions
  • Copper and brass sales - THE copper and brass supplier. Doesn't always sell small quantities. Ask for Jeremy Jennings, First.last@thyssenkrupp.com
  • Sequoia Copper and Brass - Cheap copper and brass. Sells small quantities at reasonable prices, but might take a while.
  • Online Metals - Good selection, fast shipping, reasonable prices on most things. DO NOT BUY COPPER HERE... the price is inflated by a factor of 2-3 compared to Sequoia or Copper and Brass. You can order online with a PO, use account username: jacob@cua.harvard.edu pwd: usual. Just enter PO number when asked for payment information.
  • McMaster - Good selection, reasonable prices. Don't buy if you really need a specific alloy of a metal, since they never provide any sort of material certification.
  • Brunner Enterprises - Good source for anodized aluminum.
  • Turner Steel - Steel
  • Ed Fagan - Invar, Molybdenum, Tungsten, Tantalum, Nickel
  • Admiral Metals - Aluminum, S.S., brass, beryllium, copper
  • Yarde Metals - Large diameter tubes
  • Tube Service - Large diameter tubes
  • T.W. Metals - Tubing, aluminum, stainless, nickel
  • Southern Aluminum Finishing - Aluminum sales; will do custom anodizing for good prices.
  • Rebel Metals - Aluminum and stainless. Steve approved.
  • Everest Metals - Copper, aluminum, stainless. Steve approved.
  • Cooner Wire Flexible heat links - (we use NER7710836B-OFE specifically request Cu10100 with certs)

Magnet Wire

Machining/Welding/Fabrication/Etc.

  • NewCut - Photo etch machining, up to 80 mils thick, very tight tolerances, quick turn-around.
  • Ramsay Welding - Can do aluminum welding. Has Stan's seal of approval.
  • Protolabs - Lukin Group recommended
  • Plethora - Also recommended by Lukin group, might give you a credit if you are a new customer.
  • Harvard SEAS Shops - SEAS shops
  • Shenzhen Tuofa - Custom CNC parts, dirt cheap, within spec, but long-ish lead time (2-4 weeks). The Ni lab has used them and they are really shockingly cheap, ~$60 total price (machining + material + shipping) for some reasonably complex three piece DBR housings.

Solder and Braze

Plastics and Composites

Hardware/Machining Supplies/Fasteners

  • McMaster
  • MSC - When McMaster just won't do
  • Vlier - Screws with Springs inside and more.
  • Air Incorporated - 80/20 supplier. Phone: 800-341-2800. Best to have the cut numbers and location codes (from an 80/20 catalog) ready for any anchor fastener counterboring, etc., before you call.
  • Amazing Magnets - Permanent magnets
  • K&J Magnetics - Large selection of rare-earth magnets.
  • Olander - Helicoils, including phosphor bronze and other specialty materials. Don't bother with the website, just call with a part number and tell them the material.
    • Before ordering, it helps to have a part number from a helicoil manufacturer, such as Chrislynn Inserts or Emhart Teknologies. If you need non-magnetic helicoils quickly, MSC sells titanium helicoils in many common sizes.
  • Solon Manufacturing Belleville spring washers in specialty materials, including phosphor bronze
  • United Titanium Titanium fasteners
  • Mutual screw Brass (C260) and silicon bronze fasteners
  • Cold Headers Inc. Brass and Stainless Steel socket cap screws. Cheaper than McMaser (about factor of 2). Responds and ships fast.
  • E&T Fasteners PEEK screws and other exotic plastics. Can even get them vented!
  • Accurate Fasteners Local fastener distributor
  • Century Spring All manner of springs, including non-magnetic, unusual materials, and custom
  • J I Morris - Great selection of small screws and nuts, lots of stock
  • Seastrom Manufacturing - Great selection of washers, many sizes and materials.

Computers and Computer Hardware

  • Dell Go to www.computers.harvard.edu, and select Dell departmental purchase. You will have to register; use your fas.harvard.edu email. Configure your computer (you can get any system, or a "Harvard standard" system). When checking out you will have to select a shipping address - be careful, if you select "17 Oxford St" from the dropdown list it will probably have somebody else's name attached to it. If this is your first time ordering this way, you will have to manually enter the address with your name as the recipient. For future purchases, find the "17 Oxford St" entry with your name as the recipient. Choose "pay with credit terms". The same warning about the drop-down list applies for the payment address; be sure to select the "Jefferson Business Ofc" or something like that; if you select other addresses with "Jefferson" in the name it will go to somebody else (for example a secretary in the HETG).
