@Qingdao Sigma Chemicals , I sent this email a few times but I haven't gotten a response yet. I hope it's OK to post here!
Tracy,
This is Samantha at Wuhan Jacki Chan Biotech. We are your #1 fan and appreciate you speaking so highly of us publicly recently!
I would like some info on which filters you use for your finished oil products. Do you use a 0.22, 0.45 or 0.50 micron filter?
A 0.22 micron filter is designed to effectively capture and remove bacteria, fungi, and other microorganisms that may be present in pharmaceutical solutions or suspensions. This is crucial to prevent contamination and maintain the integrity of the final product.
Is this what QSC uses on oils? We are looking to change suppliers but require oils that are free of "floaters" and filter fibers. Can you provide us with the product requested?
Also, do you carry peptides with guaranteed 99% purity and within 5% +/- advertised content? As of now, we have bad luck with our peptides, many are under purity and are contaminated with semaglutide... but some customers love the bonus Sema!
Thank you, and may the Year of the Dragon bring you fortune and luck!
