Handling & use of IPRS


IPRS are not intended for administration to human or animals as drugs or medical devices. They are intended for test and assay use only as per Indian Pharmacopoeia. IPRS should be used immediately after opening, any unused portion of the IPRS may be stored and reused is the sole responsibility of the user.


For effective use of IPRS following points may be followed:

1. If the IPRS is stored at low temperature, allow it to reach room temperature before opening the vial.
2. To eliminate any static inside the vial, tap the vial prior to removing the stopper or use an anti-static device.
3. Minimize handling steps. Weigh the material directly into the volumetric flask or other laboratory glassware being used to prepare the solution. This will reduce the risk of losing material due to static.
4. A spatula with an angled point may be more effective than the typical weighing spatula.


Storage of IPRS

IPRS should be stored between 2˚C to 8˚C.
