We advise you to go through respective units of BBCET-151 before you come to attend the practical sessions. This will enable you to easily understand the purpose of doing experiments and their applications. You should also read the principles of each experiment of this course along with procedure before you start performing the experiment. It is always good to prepare all the reagents freshly and store them under prearranged storage conditions. Adhere to all the safety measures and follow the safety instructions while handling the reagents. One of the good laboratory practices is to maintain your log books up-to-date i.e., enter the observations made while performing the experiments. Carry this laboratory manual and your log book during lab sessions.

Like all other IGNOU laboratory courses, this is an intensive residential exercise requiring one week for completing 2 credits. Everyday there will be two laboratory sessions of 4 hours each. So there will be a total of 14 sessions. The first session will be introductory and the remaining 2nd to 12th sessions will be based on the exercises given in the course. A schedule for laboratory exercises will be given to you in the first session. Sessions 1 to 12 shall have guided exercises under the supervision of the Academic Counsellor. The last two sessions i.e., 13th and 14th will be unguided sessions and that shall be the term end examination. In each session you shall perform exercises for 3 hours and in the remaining 1 hour you are advised to complete your practical note book. The laboratory notebook must be submitted to the counsellor for corrections and grading. 70% marks have been allocated for doing the experiments and for recording it properly. You are aware that there is a time constraint as you will have limited access to laboratory work; therefore, you are required not to miss any of the laboratory sessions.
