PREPARATION OF 70% IPA V/V

To prepare 70% Isopropyl Alcohol (IPA) V/V in a pharmaceutical company, follow these steps:

Decide kitna 70% IPA V/V chahiye hai.

Is formula ka istemal karke calculate karein ki kitna IPA aur pani chahiye hoga:

Amount of IPA (in ml) = Required volume of 70% IPA V/V (in ml) x 0.7

Amount of water (in ml) = Required volume of 70% IPA V/V (in ml) x 0.3

Measuring cylinder ya flask ka istemal karke IPA aur pani ka measurement karein.

Ek saaf container mein IPA daalein, aur dheere-dheere pani daalte rahein aur halka sa hilate rahein.

Hydrometer ya refractometer ka istemal karke check karein ki solution 68% se 72% concentration ke beech hai.

Container par date aur concentration ke saath label laga dein aur use se pehle clean aur dry jagah mein store karein.

IPA ki purity kam se kam 99% honi chahiye aur pani mein koi bhi impurities nahi hone chahiye. Contamination se bachne ke liye saaf jagah par kaam karein aur solution ko expiry date se pehle use karein.
