We understand how crucial fast delivery is in research environments, so we’ve optimized our order processing system. Most orders are processed and shipped within 1–2 business days of confirmation. Standard shipping typically takes 3–5 business days, and expedited shipping usually arrives in 1–2 business days. While these timelines are standard, they aren’t guaranteed. You’ll receive a confirmation email with full delivery and tracking details so you can monitor your order every step of the way.

Store in a cool, dark, and dry place, preferably in the refrigerator, and keep it away from sunlight to maintain quality and integrity.
