Pharmaceutical Microscopes

The U.S. Pharmacopeial Convention (USP) sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements worldwide. USP's drug standards are enforceable in the United States by the Food and Drug Administration, and these standards are used in more than 140 countries.

IMA/USP 788 is a test for particulate matter in injections. Method 2 of this test is a Microscopic Particle Count Test. Each IMA/USP 788 microscope listed below meets the standards required by IMA/USP 788 for the microscopic particle count test. The microscopes have the required episcopic brightfield internal illumination and oblique illumination, and each specific microscope magnification factor is determined using a NIST certified stage micrometer in order to produce the IMA/USP 788 ocular micrometer that is calibrated and installed in the microscope.

USP 751 is a test for metal particles in ophthalmic ointments. You can learn more about USP 751 test procedures here.
