====Questions====
What approximate flow rate do we need?  How do we setup our Watson-Marlow Breded Pump to obtain the necessary flow rate? 

How do we easily calculate the activation size of aerosols?

Where can we purchase a thermo-electric cooler that cools water flowing through a 1/4 inch tube?

  * Potential Answers:
    * TE Tech Liquid (Model numbers indicate capacity rating at 0 degree temperature difference)
      * Cools liquid and suited for small heat loads and lab work.  Probably the best choice thus far.  Roughly 152 x 127 x 96.9 mm.  $245.  Powered by 12 VDC.  Compatible with all TE Tech temperature controllers.  [[https://tetech.com/products/lc-035/|LC-035]]
      * [[https://tetech.com/products/lc-061/|LC-061]]  178 x 127 x 96.9 mm.  $302.  Powered by 24 VDC.  Compatible with all TE Tech temperature controllers.
      * [[https://tetech.com/products/lc-200/|LC-200]]  161 x 216 x 147 mm.  $635.  Powered by 24 VDC.  Compatible with the TC-720 series, TC-36-25 series, and TC-48-20 series temperature controllers.
    * If temperature controllers are needed, the following could be used:
      * The [[https://tetech.com/products/tc-48-20/|TC-48-20]] can be programmed with the device or can be connected to the keyboard to work with included software (source code included if necessary).  [[https://tetech.com/products/tc-48-20-oem/|TC-48-20 OEM]] works the same but does not have the keyboard or housing, to lower cost.
    * The [[http://www.dx.com/p/aluminum-water-block-thermoelectric-cooling-module-silver-173740?tc=USD&gclid=CNiTxsPH-sECFXQLMgod-XAAIw#.VGYzlLdAS70|mechanism]] through which water is cooled.  This is smaller and would be able to work with smaller plate coolers, but would require the additional purchase of a cooler and a heat sink. there is also nothing to indicate whether it is effective at cooling water.

  * Questions:
    - By how much do we need to cool the water?
    - How fast must it be cooled?
    - What kind of power source must be used?
    - Do we need a specific temperature control? [Yes?]
    - How big should the cooler be?
      - What should it be made out of?
    - How big //can// it be?
    - Do we need a pump?

  * Other, less likely answers:  
    * [[http://alliedthermaldesigns.com/?p=189|Another option]], but still quite large.
    * Tellurex
      * Cold plate cooler, Weight 600 grams, operating range -10 to -70 (Celsius), preassembled, includes heat sink.  Would need to find a way to attach the tube.  $130.  [[http://tellurex.com/shop/pk1-cold-plate-cooler/|PK1 Tellurex Cooler]]
      * SL1210 is similar to the PK1 but can draw more watts at a time, and weighs 895 grams.  $215.  [[http://tellurex.com/shop/sl1210-thermoelectric-cold-plate-cooler/|SL1210 Tellurex Cooler]]
    * TEC1 Coolers are small and compact, and have respectable temperature differentials, but they may have less control over temperature, and would require a separate heat sink.  Can be purchased from various places, $3.16-$7.92.  (May be less effective since it does not seem to be sold by any specific company.  May require more than one.)

    *TE Tech
      * High temperature models operate at temperatures between -40 and 200 and have dimensions 40 x 40 x 40 mm or less.  $15.30-$52.50. Degree of temperature control unknown, and water protection would likely be extra.  [[https://tetech.com/peltier-thermoelectric-cooler-modules/high-temperature/|High Temperature Modules]]
      * Standard models' size varies more, $12-$59.  Similar to high temperature, but only operational up to 80 degrees.  [[https://tetech.com/peltier-thermoelectric-cooler-modules/standard/|Standard]]
      * Similar for High Performance [[https://tetech.com/peltier-thermoelectric-cooler-modules/high-performance/|High Performance]]
      * Cold Plate coolers with heat sinks are also available, but it works best at lower temperature differences.  $169.  [[https://tetech.com/products/cp-031/|Cold Plate]]

  * Notes:  
    * Tellurex has thermoelectric coolers, but there is uncertainty over whether they can cool a 1/4" tube directly.
    * TE Tech has cold plate coolers that could work for cooling a tube of water, but they would likely require an adapter plate.
    * Tellurex comes pre-assembled; TE Tech's require assembly. 
    * TEC Microsystems has a large variety of smaller thermoelectric coolers, but there are no listed prices.
    * Thermoelectric liquid chiller/cooler might be an equally viable search term.
      * Liquid chillers seem much more bulky and less compact.
    * The heat sink will likely be much bulkier than the actual cooler.  Plate coolers are generally compact and thin, but the heat sinks cover a larger area and are much thicker.
    * Heat sinks are slightly more difficult to find on their own, and are 2-3 inch diameter circles.
