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

Chemicals and materials

Ceramics

Metals

See also: #Chemicals_and_materials

  • 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
  • Yarde Metals - Large diameter tubes
  • Tube Service - Large diameter tubes
  • T.W. Metals - Tubing, aluminum, stainless, nickel

Welding

Ramsay Welding - Can do aluminum welding. Has Stan's seal of approval.

Plastics and Composites

Hardware/Machining Supplies/Fasteners

  • McMaster
  • MSC - When McMaster just won't do
  • RAM mounts - Mounts for scopes and other instruments.
  • 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.
    • 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

Optics

Essentials

Specialty

Laser Diodes

PMT

Hamamatsu PMT contact Rich at (908) 252-7728 Fax: (732) 537-3678

Electronics

Sensors

  • Micromagnetics Magnetoresistance-based B-field sensors
  • Honeywell Anisotropic magnetoresistance (AMR) magnetic sensors. Noise is < 1 uG/rt-Hz @ 10 Hz. ~20$ each.

Vacuum

Manuals from lots of companies for lots of old pumps & controllers

Essentials

Specialty

  • InstruTech - Makes compact, digital convectron and ion gauges at good prices.
  • AVS Technical Resources - Useful calculator for conversion factors, pump/gauge ranges
  • Varian High quality dry scroll and turbo pumps at competitive prices. Don't send purchase orders to the sales rep, though. Instead, email them to vtl.purchaseorders@varianinc.com.
  • Precision Cryo Ask for Dick Gummer. They made the EDM beam source chamber.
  • Kimball physics - special (cool) chambers
  • Sharon - custom chambers
  • Key High
  • vacuum generators Best quality UHV all-metal valves.
  • Insulator Seal - Feedthroughs
  • Apiezon Greases and Waxes
  • EVAC Vacuum - Unique! Standard QF/ISO hardware, but made out of glass(!), aluminum, etc.
  • accuglass products - Unusually nice selection of feedthroughs, in-vacuum electrical connectors, hardware, etc. Prices better than Lesker.
  • MPF Products - Similar to accuglass for electrical feedthroughs, but also has nice selection of viewports
  • Atlas UHV - UHV grade welded aluminum vacuum chambers. Made the EDM interaction chamber.
  • Heating Tapes
  • All Foils UHV clean aluminum foil

Cryogenics

Gases and Flow Control

  • MKS Instruments - Flow controllers.
  • Laminar Technologies - Sells used MKS flow controllers. The Harvard cleanroom manager (Noah Clay) claims that used flow controllers are better (since they are screened for infant death), and of course they are cheaper.

Quasi-Optical, Microwaves

mm-wave Microwave Components

  • Quinstar - Large selection of waveguide and coax, ask for Sage Kuno
  • Miteq - Largest supplier (and stock) but more expensive

Optical detectors, PMTs

Coatings, deposition

Electroplating

Diamond-Turned Optics

Actuators and Motion Control

Vibration Isolation

Waterjet

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).
  • Dell's Harvard Pricing WARNING: they are not necessarily cheaper than dell.com
  • NewEgg Computer accessories. WARNING: they do not accept POs.
  • Lenovo Harvard Pricing Departmental and Personal
  • For CDW order, send PO to Mecca Nnacheta meccnna@cdw.com
