Temperature and humidity are just two factors that need to be upheld to avoid scrutiny, contamination, comfort for personnel, and maintain a positive safety culture. In the U.S the Food and Drug Administration’s regulatory guidelines outline an optimal temperature for labs as being between 68 °F and 77 °F (20 °C and 25 °C) with […]

Micropipette calibration is typically performed using the gravimetric method, where the volume dispensed is determined by measuring the weight of distilled water. 𝐒𝐭𝐞𝐩-𝐛𝐲-𝐒𝐭𝐞𝐩 𝐆𝐫𝐚𝐯𝐢𝐦𝐞𝐭𝐫𝐢𝐜 𝐂𝐚𝐥𝐢𝐛𝐫𝐚𝐭𝐢𝐨𝐧

Media filling, also known as media fill or aseptic process simulation, is a validation method used in the pharmaceutical industry to simulate the actual sterile production process. During media filling, a sterile growth medium (usually a nutrient-rich broth that supports microbial growth) is filled into containers, vials, or syringes instead of the actual product.This process

Sterility refers to the complete absence of viable microorganisms, including bacteria, fungi, and spores, on a product or in a substance. In the pharmaceutical industry, sterility is critical for products like injectables, ophthalmic solutions, and surgical instruments to prevent infections and ensure patient safety. Sterility testing is a key process in quality control to confirm

The bacterial endotoxin test (BET) is a crucial assay used to detect the presence of endotoxins, which are toxic components found in the outer membrane of Gram-negative bacteria.Endotoxins can trigger severe immune responses in humans and animals, making it essential to monitor their levels in pharmaceuticals, medical devices, and other products that come into contact

The limits for Microbial Limit Test (MLT) for raw materials and finished products are defined based on the product category and regulatory requirements, such as those from pharmacopeias like the United States Pharmacopeia (USP), European Pharmacopoeia (Ph.Eur.), or Indian Pharmacopoeia (IP).

The sample size for MLT is based on harmonized compendial requirements, where the sample quantity and media dilution are maintained at a 1:10 ratio. In fact, this is one of the drawbacks of this test, as duplicate or triplicate analyses are not always performed.Statistically, based on the dilution requirements, the minimum sample size is selected
