The right selection starts with knowing what is in the package. Compare the product system first, then choose the size, bottle material and kit count.
HCl kits and citric acid kits
Hydrochloric acid (HCl) kits and citric acid kits are separate two-component systems. Their components and directions are not interchangeable. One liquid kit contains one bottle of each matched component, two droppers and two caps. Multipacks contain the corresponding number of complete kits.
Prepared solution
Chlorine dioxide solution 0.3% (3,000 ppm) is a separate prepared product. Review its own product information and safety data sheet rather than liquid-kit directions.
Individual components
Individual components are replacement bottles, not complete kits. Match the chemical name, concentration, volume and bottle material before ordering.
Check the selected variant
Size, material and pack count are selected on one product page. Check the displayed SKU, price and included items before adding your selection to the cart. Some temporary gallery images represent the product family rather than every offered pack size; the selected variant details identify what you are purchasing.
Read the matching safety information
Available safety data sheets are linked near the purchase controls and in the SDS Library. A safety data sheet is not a substitute for product directions. If a document is marked as a placeholder, request the complete information before handling the product.
