58° Angle Borosilicate Glass Filtration Funnels

These laboratory filtration funnels are made of high-quality borosilicate glass with a precise 58° cone angle. The narrower angle enhances filtration efficiency by preventing filter paper from sealing against the glass, allowing better flow. Designed for chemical resistance and durability, these funnels feature heavy-wall construction with reinforced, fire-polished edges for long-term laboratory use.

Ascorbic Acid (Vitamin C) USP/FCC, Kosher 99% - 100.5%

Ascorbic Acid, commonly known as Vitamin C, is a high-purity compound (99% - 100.5%) with multiple applications in pharmaceuticals, food additives, and cosmetics. This potent antioxidant is vital for health and is used in the production of supplements, fortified foods, and skincare formulations. It appears as colorless crystals or white to nearly white powder, meeting rigorous BP/USP/EP/FCC/E300 standards. Its solubility in various alcohols like propylene glycol, glycerin, and isopropyl alcohol makes it versatile for different formulations. Ascorbic Acid offers excellent stability when stored in dry, light-protected, and cool conditions, but it is sensitive to moisture, heat, and oxidative materials. Certified kosher and available with a Certificate of Analysis (COA) for bulk orders, it is a reliable choice for commercial and industrial use. Lead, iron, and copper content are tightly controlled (≤10 ppm, ≤2 ppm, and ≤5 ppm, respectively) to ensure purity and safety. Perfect for pharmaceutical manufacturers, food industry professionals, skincare formulators, laboratories, and wholesale buyers.

Product Specifications

Applications and Benefits:

• Production of dietary supplements
• Fortification of foods and beverages
• Antioxidant in skincare formulations
• Used in pharmaceutical preparations
• Soluble in alcohols for formulation versatility

Caution:

Store in a cool, dry, and light-protected environment. Sensitive to heat, moisture, and oxidative agents.
