EL Labs operate as an FDA-inspected, GMP/MIA-certified, quality control laboratory for human and veterinary medicinal APIs, excipients, intermediates, finished products, packaging materials and water. We offer a wide range of physical-chemical, microbiological, and biological services in accordance with ICH guidelines,applicable pharmacopoeia (EU, USP, BP) or manufacturers indications. As a GMP-certified testing site we offer:

• Method validations or verification and analytical method transfers.
• Quality control testing of pharmaceutical raw materials, active substances, and excipients.
• Routine batch testing for the release into the EU market of batches of drugs produced in third countries.
• Stability studies of medicinal products including storage and stability testing.
• Testing of waters for pharmaceutical purposes.
• And more..
