CHECK-IN PROCEDURE: Compare the contents of the locker with the items listed on the equipment list. Circle, on the page, the names (and when needed for clarity, the sizes) of missing items. Then carefully inspect the items on hand for defects. Especially look for cracks in glassware. The rims of glassware and the tips of pouring lips are frequent sites of damage. Poke the crucible bottom with a finger to expose hidden cracks. Be sure the case contains a thermometer and that it is in one piece. Poke the wire gauze to ascertain whether it is free of cracks and holes. Circle item names (and sizes) of all defective items on the equipment list. The following kinds of defects are not serious enough to cause replacement:

1. Rust or corrosion on metal items.
2. Damage to the clay cylinders on the wire triangle.
3. Brushes that are in less-than-mint condition but are still intact and usable.

Be careful about what you accept at the start of the course. Scratched glassware, especially test tubes, should be replaced. The Chemistry Department does not charge a lab fee. Therefore, you are responsible for any equipment damaged or broken during the course. At the end of the course you will be charged for all missing or defective items. When all questionable items have been noted on the equipment list, confer with the instructor. After checking questionable items, the instructor will send you to the stockroom to obtain replacement items and the combination to the locker. Matches are no longer used for lighting bunsen burners but have been replaced by the strikers on the equipment list. No freebies will be issued by the stockroom after the day of check-in. After obtaining the locker combination, try it. Inform the instructor of any difficulties. Keep the locker locked except when you need access to it. Equipment has a habit of disappearing from open lockers.

CHECK-OUT PROCEDURE: Remove all equipment from the locker and place it on top of your bench. Clean and dry all glassware. Dirty glassware is not acceptable! Scratched test tubes should be replaced. The Chemistry Department does not charge a lab fee. Therefore, you are responsible for any equipment damaged or broken during the course. Place the thermometer beside the case. Donot leave any items in the locker not on the equipment list: discard such items or take them with you. Sign out replacements for all missing or damaged items from the stockroom. Then request the instructor to inspect your equipment. After the instructor's approval has been obtained, lock the locker.

BREAKAGE BILLS: Bills for breakage and/or loss are not mailed out. They will be available for payment at the cashier's office in the Student Services building the second or third day of finals week. An itemized list of persons having charges will be posted on the bulletin board adjacent to the stockroom and the cashier at the annex will have a list. The administration, upon receipt of the list will flag the record of each billed individual and hold up all services.(registration materials, grades, transcripts, student aid, etc.) until the bill is paid.
