GENERAL INSTRUCTIONS TO THE STUDENTS

Apparatus

▪ Check each piece of apparatus, which you find in your locker from the duplicate list furnished to you by your instructor. Sign your name and submit to your instructor. The instructor signs the checklists and gives one copy to you for your safekeeping. ▪ Provide your locker with reliable padlock. You are responsible for all the apparatus issued to you. Towards the end of the semester you have to replace or give a deposit for any piece which you have lost or broken. If you have partners, each of you will share equally any loss or breakage of apparatus kept in your lockers and those borrowed from the stockroom. A clearance duly signed by the laboratory attendant is a requirement for taking the final examination. NO CLEARANCE, NO FINAL EXAMINATION. ▪ General apparatus, e.g., Bunsen burner, thermometer, iron stand, clamps, etc. and special apparatus may be borrowed from the laboratory attendant. ▪ Borrowing of apparatus from the stockroom should be done during the first 30 minutes of the laboratory period.

Materials and Other Requirements

You have to provide yourself with the following materials and supplies besides the apparatus in the laboratory locker and the stockroom:
