Technical Grade Sulfuric Acid 40% — 55 Gallon Drum

Professional-grade sulfuric acid for precise pH correction in irrigation, fertigation, and hydroponic systems. At 40% concentration, this technical grade formulation is the preferred choice for large-scale commercial operations managing high-alkalinity source water. The 55 gallon drum is the most economical option for facilities running continuous automated pH dosing systems with high daily acid consumption.

⚠️ HAZARDOUS MATERIAL — UN2796, Class 8, Packing Group II. Sulfuric acid with 51% or less acid concentration. Handle with appropriate PPE. Review SDS before use. Drum pump recommended — available separately.

Key Features

• 40% concentration — technical grade purity for consistent, predictable pH adjustment

• No unwanted ions — does not introduce chloride, phosphate, or other ions that can interfere with nutrient programs
• Compatible with all systems — suitable for drip irrigation, NFT, DWC, and automated fertigation injection systems
• 55 gallon drum — best cost-per-gallon for high-volume commercial operations; drum pump compatible

Applications

• Large-scale commercial greenhouse and nursery fertigation pH correction
• Automated hydroponic pH dosing systems
• High-volume irrigation alkalinity management

Safety

Always add acid to water — never add water to acid. Use a compatible drum pump for dispensing — never tip or pour directly from the drum. Wear chemical-resistant gloves, face shield, and appropriate protective clothing when handling. Keep away from incompatible materials including bases, oxidizers, and organic materials. Review the full SDS before use.
