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

  • 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.

  • 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.

  • 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).
