I'm looking for food-grade nitrous oxide with a purity range of 99-99.99%. Specifically, I need a configuration that totals 5.3 KG per purple tank, comprising 3.3L and an additional 2KG. It's crucial to ensure that the purity meets the required standards, as poor quality could lead to serious health risks. Additionally, I would like to confirm if scanning the QR code on the certification directs me back to the CCIC website for verification purposes. My delivery location is in Jinshan Fine Chemical Industry Park, Shunchang County, Nanping City, Fujian Province. Looking forward to your prompt response regarding these details.
