Important Notes: You will purchase a Chemistry Lab Voucher from the Snow Campus Store for $15. In exchange for the voucher, your professor will give you the instructions for the weekly lab experiments. Most professors hand out the instructions for the experiments in packets, week by week. The voucher covers the cost of printing the lab packets. You will also need to purchase a pair of safety goggles, which are available in the Campus Store for about $15. If you want to buy your safety goggles independently, we recommend UVEX Stealth Safety Goggles.
