TAYLOR R-0012-C 2OZ HARDNESS REAGENT
Product Overview
Spec-calibrated for drop-count titration, Taylor R-0012 delivers distinct calcium endpoints to safeguard plaster and equipment.
Taylor R-0012-C is an EDTA titrant designed to measure calcium hardness in residential and commercial pools. Sized in a 2 oz (60 mL) bottle, this R-0012 replacement solution fits standard Taylor testing kits such as the K-2006 series. Packaged under part number R-0012-C-12 in a 2OZ volume, it ensures uniform drop volume to prevent under- or over-estimating pool saturation index.

Benefits & What Makes It Different
Standardized Drop Volume
The 2 oz dropper tip dispenses consistent drop sizes essential for 10 ppm or 25 ppm CaCO3 resolution.
Formulated for Precise Endpoints
Formulated with stabilized EDTA to react cleanly with calcium ions and produce a sharp transition from red to pure blue.
Extended 2OZ Supply
The 60 mL bottle supplies enough titrant for dozens of seasonal water tests, preventing unexpected shortages mid-season.
Product Details
Disodium Ethylenediaminetetraacetate (EDTA) aqueous solution
Titrate drop-by-drop into prepared sample until red turns to pure blue; each drop equals 10 ppm or 25 ppm depending on sample volume.
Compatibility
- Taylor K-2005 series test kits
- Taylor K-2006 and K-2006C series test kits
- Taylor K-1770 total hardness test kits
When To Use This
Pro Tip
Always hold the 2 oz bottle completely vertical when dispensing drops into your comparator tube. Inverting at an angle changes the droplet surface area, distorting drop size and giving you false hardness readings by as much as 20 to 30 ppm.
Common Questions & Instructions
How do I use Taylor R-0012-C to test pool calcium hardness?
In a 25 mL sample with R-0010 buffer and R-0011L indicator added, swirl the water, then add R-0012 drop by drop until the solution turns from red to pure blue. Multiply total drops by 10 to calculate calcium hardness in ppm.
What is the shelf life of the Taylor 2 oz Hardness Reagent?
Taylor recommends replacing reagents like R-0012-C annually, as heat, direct sunlight, and prolonged air exposure can degrade the EDTA concentration and skew your drop count.
Will this 60 mL R-0012 bottle fit standard Taylor comparator boxes?
The 2 oz (60 mL) 'C' bottle size is larger than the standard 0.75 oz 'A' size bottles found in compact test kit cases. While it may not fit molded plastic slots, it serves as a cost-effective refill for routine route maintenance.
