I'm looking to purchase water-soluble and hypoallergenic ultrasound gel in large quantities. Specifically, I need it packaged in 5-liter bottles. The gel must meet high-quality standards, ensuring that it's not only water-soluble but also hypoallergenic, providing a safe option for various applications. Could you provide detailed information regarding the product specifications, pricing, minimum order quantities, and availability? Additionally, please let me know about any certifications or quality assurance processes you have in place. Your prompt response would be greatly appreciated as I'm looking to finalize this procurement soon.
