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, but technical support is of little help.
  • Renco Corporation - sells glovebox gloves
  • Thermo Scientific - general lab supplies, including furnaces

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

  • ESPI - expensive, but has everything
  • Goodfellow
  • Rembar- Good for Tantalum, Tungsten etc
  • 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.
  • 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

  • Amazing Magnets - Permanent magnets
  • K&J Magnetics - Large selection of rare-earth magnets.
  • Olander - Helicoils, including phosphor bronze and other specialty materials.
    • 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.

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).
