Equipment choices for CHM130LL field chemistry
Field chemistry

The equipment below is slanted to the idea that the kit is a field chemistry kit. That means less breakable items would be in the kit. Also, the items may not be as accurate as those in a traditional lab, but good enough for initial analysis.

tool case

Aluminum case (This is a more rugged version of the one I use for CHM107).

Vendor: Harbor Freight
http://www.harborfreight.com/18-inch-x-12-3-4-quarter-inch-x-6-inch-aluminum-case-39196.html

Price: $29.99 but $24.99 when on sale.

May be able to purchase locally to save shipping but there are taxes.

Order 17 on July 16 from Harbor Freight online.

balance

Digital Balance (0.01 gram accuracy. 300 grams max)

Vendor: HoHoTrade.com

http://www.hohotrade.com/001-300g-mini-digital-jewelry-balance-pocket-scaletcghr31033-p-15059.html

Price: $20.99. Shipping is $15 for first. $6 each for 10 or more.

Shipping can take a week. I like the look of this one but the cost may be too high.

balance

Digital Balance (cheaper version) (0.01 gram accuracy. 300 grams max)

Vendor: DealExtreme.com

http://www.dealextreme.com/p/pocket-precision-digital-scale-300g-max-0-01g-resolution-15764

Price: $16.54. Shipping is free.

Shipping takes about 3 weeks. I ordered 3 of these 6/4/11.
Arrived around 6/25/11

Ordered 21 on 7/14. Bulk rate is $16.34 each with total of $342.14. Shipping is $1.70 for registered Air Mail. Your receipt number for this payment is: 3012-5016-7622-7827

torch 

Butane micro-torch.

Vendor: Harbor Freight

Price: $8.

High but focused temperatures are possible. Safety is probably midrange. It's only $8 at Harbor Freight.  Found others a DealExtreme.  I ordered a couple of them but haven't test them yet.  Probably won't use them in kit.

Wickless Alcohol Burner, Steel, Single Head

Vendor: Online Science Mall

http://www.onlinesciencemall.com/Shop/Control/Product/fp/vpid/1787008/vpcsid/0/SFV/30852

Price: $14.95 ($7.60 shipping cost)

All metal, leak proof alcohol burner. Permanent wick, no replacements needed. Tank capacity 100mL, sufficient for 1.5 hours of use. The 'wick' portion is a ceramic fiber inserted into a thin copper tube. This construction allows for constant flame. The burner is fueled by denatured ethanol or Everclear 95% ethanol. A draft shield, flame snuffer, rubber keeper and instruction manual are included. This unit can be tipped and will not leak. The chrome plated tank is fitted with a screw top and rubber gasket for longer burning times. The burner is 3 wide by 3 1/8 high.
alcohol burner and stand

Wickless Alcohol Burner, Steel, Single Head

Vendor: Home Science Tools

http://www.hometrainingtools.com/alcohol-lamp-stand-set/p/CE-LAMPKIT/

Price: $10.95 ($9.95 for 10 or more) (low shipping costs) 8.40 for burner alone.

This is the cheapest one found so far. The video they showed said this can boil 250mL of water in about 10 to 15 minutes. It would be a good idea to have a ceramic tile for the burner to sit on since the metal base gets quite hot.
This site has instructions on set up and use of this burner. See link below.

http://www.hometrainingtools.com/images/art/CE-LAMPWeb.pdf

I ordered one of these on 6/6/11. Arrived.

Ordered 24 on 7/14. Cost $238 plus $6.95 shipping

 

Sterno

Sterno (alternative to alcohol burner above)

Vendors: Multiple ones

Price: About $2.50 for 2.6 oz version.

These are a cheaper way to go for minimum usage. So it depends on how much heating will be needed in the labs.

 

candles

Tea Candles

Vendors: Many

Price: Cheap

Probably the safest and cheapest heat source but put out the least amount of heat. These tea candles are what is put in the chemistry kits used by South Mountain. In some situations, the heat from a candle is all that is needed. However, for boiling water (except in a test tube) these wouldn't work.

Perhaps the kit can have more than one kind of heat source if the prices are low enough.

clamp

Right angle clamp

Vendor: Home Science Tools

http://www.hometrainingtools.com/clamp-right-angle/p/CE-RCLAMP/

Price: $2.90 when ordering 10 or more. Shipping cost low.

I ordered 10 on 6/6/11. Instead of a ring stand, this might clamp to side of the kit's case. The extension clamp below may be used to hold test tube or flask. Arrived (Probably will not used in kit)

extension clamp

Extension clamp

Vendor: Home Science Tools

http://www.hometrainingtools.com/extension-clamp-10/p/CE-CLMPEXT/

Price: $6.95

I ordered one on 6/6/11. This came in but didn't look like the one in the photo. Hook up to case doesn't quite work with the right angle clamp. Arrived, but looks different than photo. (Probably will not used in kit)

multimeter

Multimeter

Vendor: Harbor Freight

Price: $4  ($2.99 online but shipping was about $14 for whole )

The kit could use a multimeter for doing conductivity (electrolyte) tests . It could also be used for activity series, single-replacement reactions, and other electrochemical reactions. There will be a need to adapt the existing probes to probes that will be inert such as carbon (like mechanical pencil lead). Platinum would be better but too expensive. (Decided not to use multimeter as TDS meter). Will buy TDS meter, but may still get multimeter for other experiements.

graduated cylinder

Graduated Cylinders (100mL and 10mL, plastic, light weight)

Vendor: Delta Education

http://www.delta-education.com/productdetail.aspx?campID=D610&PartNo=070-2140

Price: $2.45 for 100mL, $1.50 for 10mL (plus shipping)

This is a cheap version of those used in labs, but it is lightweight and the plastic is very clear for good observation of the meniscus. These are like the ones used by Rio Salado and South Mountain.

Will look for 10mL grad cylinder with 0.1 mL markings (Found one. See below). Decided to also get the 25mL grad cylinder as well.

Ordered 24 100mL graduated cylinders 7/14 at $2.50 each
Ordered 24 25mL graduated cylinders 7/14 at $1.75 each
Subtotal $100.80

Shipping $12.10. Sales Tax $6.32 . Grand total $119.32.

Price: $3.49 for 10mL, (plus shipping)

This one has 0.1 mL markings. 3 ordered on 6/24 (Arrived)

21 ordered from Amazon on 7/15. Price had jumped to $3.75. Total $78.75. No shipping cost due to Super Saver Shipping.
