Additional Chemicals Needed:
There are some additional chemicals that cannot be included in the advanced CHEM kits due to safety restrictions and their limited shelf-lives. I have put together the following list of the chemicals you will need below.
Additional Chemicals Needed for CHEM C3000 (due to legal restrictions or limited shelf life)
• Approximately 10 ml of silver nitrate solution, (1% Solution)
• Approximately 100 ml of sodium hydroxide, 1mol/L (4% Solution)
• Approximately 100 ml of hydrochloric acid, 2mol/L (7% Solution)
• Approximately 50 ml of ammonia solution 2mol/L (3.4% Solution)
70% Ethyl Alcohol (a form of Denatured Alcohol), and Hydrogen Peroxide are also required for certain experiments but cannot be included in the kit due to certain restrictions. You should be able to find these two items in the first aid aisle of most pharmacies.
Ammonia should be obtainable from most supermarkets in the cleaning aisle. Generally speaking, household cleaning ammonia will typically range in concentration from 5% to 10%. The product labeling should indicate the concentration.
The proper dilution of ammonia solution is approximately 3.4%, and this can be attained by adding common household ammonia to the appropriate amount of water (see below). The amount of water that you will need depends on the volume required for a given experiment and the percentage of the solution you are starting with.
**Important!** When diluting chemicals, always add the chemical to the water, not the other way around. In general, if you pour water on top of certain chemicals, a reaction can occur quickly causing the solution to splash back up at you. However, if you carefully add the chemical to the water, you can avoid this.
You may find it easier to create a larger volume of properly diluted solution and store it for use as needed.
As an example, let’s assume that you are starting with household ammonia which is at an 8% solution. If you wanted to make a 4% solution from that, you would combine equal parts water and ammonia. By adding 25ml of ammonia (@ 8% by volume) to 25ml of water you would thus create a 4% solution.
Therefore, to reach a 3.4% solution, you would need to dilute the ammonia by a little more than half.
Once again, let’s assume that you are starting with an 8% ammonia solution. If 50 ml of ammonia solution is required, you would need to add 21ml of ammonia to 28ml of water. (3.4%/8% = .425 -> .425 x 50ml = 21.25ml, or approx. 21ml).
Inserting the wick into the burner assembly:
Once you have put the wick holder and aluminum disk together, push one end of the wick into the top hole of the wick holder (so that just the end is completely inside of it).
Next, twist the wick clockwise while pushing it further into the wick holder, and it should make its way through fairly easily. 
If your wick has mushroomed a bit, you can use masking tape to make a pointed end and thread the wick through that way. You can also use a pair of scissors and trim it down so that it isn't as wide at the end and try the steps listed above.
International Transport
The CHEM C3000 kit does contain small quantities of materials which, in terms of transport, are classified as hazardous. However because the hazardous materials are in small quantities, the kit complies with 49 CFR 173.4 and therefore receives a “Small Quantity Exception” for domestic transportation. We have included some additional details below, but because each country will have its own regulations, we suggest checking the specific regulations of your air carrier and with the country that you will be visiting for more specific details.
Domestically, there is a Small Quantity Exception for Air Transportation, 49 CFR 173.4a, which is approved by UPS, FedEx (page 8), and USPS. The small quantity exemption would still require additional labeling for air transport (see below), but no shipping papers or other hazard labels would be required.
Excepted quantities of hazardous materials packaged, marked, and otherwise offered and transported in accordance with this section must be durably and legibly marked according to 16 CFR Section 173.4a (g) Marking. Look for "Excepted Quantities Labels".
(1) The “*” must be replaced by the primary hazard class, or when assigned, the division of each of the hazardous materials contained in the package. The “**” must be replaced by the name of the shipper or consignee if not shown elsewhere on the package.
(2) The marking must not be less than 100 mm (3.9 inches) by 100 mm (3.9 inches), and must be durable and clearly visible.
Please Note: We would not recommend attempting to take this item as carry-on luggage on a flight. Again, if you are considering this, we suggest that you check with your carrier for approval first and provide them with all of the information presented here.
