Glacial Acetic Acid 99.9% (16 Fl Oz) — UniClean America
Product highlights: Glacial Acetic Acid High purity 99%. This 99.9% concentration suits precise cleaning, metal prep, and small-scale lab tasks. Made in the USA, this option is ideal for hobbyists and small shops that require reliable, domestically produced acetic acid.
Best for: Small workshops, DIY enthusiasts, and culinary prep that benefits from high-purity acid. Consider this for controlled experiments or spot cleaning where a smaller quantity is preferred.
Limitation: Limited volume means more frequent reordering for large-scale tasks. Suitable for consumer uses rather than long-running industrial operations.
950ml Food Grade Glacial Acetic Acid (99.85%+)
Product highlights: Food-grade glacial acetic acid, 99.85%+ purity. The liquid can freeze at 62°F, and it’s suitable for culinary, cleaning, and general food applications. Also useful for transforming into dilutions (e.g., common vinegar) for cooking or sanitation tasks.
Best for: Home cooks and small kitchens needing a food-grade acid for specialty recipes or safe sanitation. It’s a practical fit where purity and food-grade status matter.
Limitation: The ability to freeze at typical room temperatures requires storage considerations or gentle warming before use.
Glacial Acetic Acid 99.9% Concentration — Gallon (128 fl oz)
Product highlights: High-purity acetic acid intended for industrial, commercial, and personal applications. The gallon size supports heavier workloads and continuous use in facilities or workshops that require reliable, bulk supply.
Best for: Small to mid-size businesses, labs, or facilities needing a bulk supply of glacial acetic acid for processing or cleaning tasks. This option emphasizes versatility for various projects.
Limitation: Not all users require such a large quantity; storage and safety handling should be planned for bulk containers.
5 Gallon Pail Food Grade Glacial Acetic Acid
Product highlights: Food-grade glacial acetic acid in a 5-gallon pail. High purity makes it suitable for extensive culinary prep, large-scale cleaning, and industry-related uses where a steady supply is essential.
Best for: Restaurants, food processors, and labs that require bulk quantities with food-grade assurance. It supports sustained operations without frequent restocking.
Limitation: Bulk storage requires compatible containment and safety practices due to the chemical’s corrosive nature.
Acetic Acid, 17.4 M (30 mL) ACS Grade
Product highlights: ACS Grade glacial acetic acid at 17.4 M. This tiny, precise volume is designed for laboratory-grade experiments and accurate titrations. It carries explicit chemical-grade labeling for controlled scientific work.
Best for: Academic laboratories, research projects, and precise formulation tasks requiring exact molarity. Use this when exact measurements and high-grade purity are critical.
Limitation: The small volume may necessitate more frequent purchases for ongoing experiments or larger projects.
Buying Guide
Key purchase considerations help tailor choice to task and environment. Use these criteria to compare products beyond purity alone.
Purity and grade
Choose higher purity (99%+ or ACS grade) for lab work, metal prep, or precise culinary experiments. Lower-purity options may suffice for cleaning and general use.
Volume and storage
For kitchens or small shops, 16 oz or 950 ml bottles are convenient. For rooms with ongoing needs, bulk options like gallons or 5-gallon pails reduce reordering and price per unit. Store in a sealed container away from heat and incompatibles.
Food-grade vs. industrial-grade
Food-grade acetic acid is essential for culinary and some cleaning applications. Industrial-grade products offer versatility but may require stricter handling and safety measures.
Intended use
Laboratory users benefit from ACS-grade liquids with precise concentrations. Home users should select products with clear usage guidance and safe packaging for non-lab environments.
Safety and handling
Glacial acetic acid is corrosive. Use appropriate PPE, work in ventilated spaces, and store away from incompatible substances. Follow container and label directions for dilution, transfer, and disposal.
FAQ
- What is glacial acetic acid? It is acetic acid with very high purity, typically around 99% or more, used in cleaning, cooking, and laboratory tasks.
- Is glacial acetic acid safe for cooking? Yes, when labeled food-grade and used as directed in recipes or sanitation tasks.
- What storage considerations exist? Keep in tightly sealed containers, away from heat and moisture; avoid storing near bases and oxidizers.
- Which size should I buy for a beginner? A small bottle (16–950 ml) is ideal to start, especially for non-commercial tasks.
- Can I use the same product for lab tests and cleaning? Some products are suitable for both, but verify grade and safety data before use.
