USP <788>
The United States Pharmacopoeia (USP) Test Section <788>, USP 788 defines the allowable limits of particulate matter in parenterals. Specific limits are set forth for particles above 10 and 25μm. The ASPEX Rx is the ideal tool to perform automated Microscopic Particle Count Testing of an entire sample deposited on a filter membrane.
