Where can I find used science kits?

Good Will  and eBay frequently have eScience Lab kits.  This Geology kit on eBay is a good example.  What are eScience kits?  Students taking online science kits both at community colleges and four year schools often do labs at home.  Instructors at college can customize these kits for their classes.  Sometimes used kits have a cd with labs.  Sometimes, the student taking the online science class manages to pass without doing any of the labs.  Students sell used kits online.  Often the contents are pristine.

I have purchased several used kits—mainly from Good Will, occasionally from eBay.  If I can get a kit for $25-30 with shipping and plenty of equipment, I’ll buy or bid on it.  Often the lab kits have digital scales, plastic cylinders and beakers, pipets, etc. (I’m not buying the kit for the chemicals.).   Look at the contents first.  For example, this geology kit looks exciting.  However, rock or mineral kits are only $16 each.  Amazon has digital scales like those in the lab kits.  The price varies—right now a scale is $7.42 with shipping on Amazon.  (I learned about these scales from an eScience kit.  One of these scales were in a lab kit.  I searched until I found similar scales on Amazon.  BTW the scales work well and withstand hard use.)

If you had your heart set on buying the Apologia MicroChem kit, eBay has them, too.  Home Science Tools has fair prices on all of their goods.  With that said, I compare prices for science equipment individually, in sets, or in kits from Amazon, eBay, and Good Will.  Keep an eye on eBay and Good Will for these eScience or Apologia kits.  I cannibalize the labs for the equipment; the small bottles of indicators or chemicals are just a bonus.
