TAYLOR .75OZ CALCIUM BUFFER REAGENT
Product Overview
Precipitates magnesium ions so drop tests measure pure calcium hardness rather than total hardness.
Taylor R-0010-A is a dedicated calcium buffer reagent packaged in a standard 0.75 oz dropper bottle (catalog .75OZ). It raises water sample pH above 12 to precipitate out magnesium, isolating calcium ions for an accurate drop-count titration. While Taylor also manufactures larger 2 oz and 4 oz commercial refills, this 0.75 oz bottle fits standard Taylor 2000 Series test kit cases.

Benefits & What Makes It Different
Magnesium Precipitation
Shifts sample pH above 12.0 so only calcium ions react during testing, preventing skewed high readings.
Precision Dropper Tip
Delivers uniform 0.75 oz drop sizing per test run, maintaining consistent drop volume across titrations.
Direct Test Kit Replacement
Matches factory slots in Taylor K-2005, K-2006, and commercial service testing kits without modification.
Product Details
Sodium Hydroxide solution (<10%)
Add 10 drops to a 25 mL sample (or 5 drops to a 10 mL sample) before adding indicator dye
Compatibility
- Taylor K-2005 Test Kits
- Taylor K-2006 and K-2006C FAS-DPD Kits
- Taylor 2000 Series titrators
When To Use This
Pro Tip
Always hold the bottle completely vertical when dispensing drops. Tilting the dropper creates smaller, irregular drops that throw off the buffer ratio and cause erratic calcium readings.
Common Questions & Instructions
What does Taylor R-0010-A Calcium Buffer do during a water test?
Taylor R-0010-A raises the water sample's pH above 12. At this high pH, magnesium precipitates out of solution as magnesium hydroxide. This guarantees that subsequent titration with R-0012 measures solely calcium hardness rather than total hardness, allowing pool owners to maintain the target 200 to 400 ppm range.
How long does a 0.75 oz bottle of calcium buffer reagent last?
Stored in a cool, dark cabinet between 36°F and 85°F, R-0010-A lasts approximately 12 to 24 months. Each 0.75 oz bottle yields about 375 drops, sufficient for roughly 37 tests using standard 10-drop protocols before requiring a new bottle or 4 oz benchtop refill.
Is Taylor R-0010-A interchangeable across all Taylor test kits?
Yes, this 0.75 oz dropper bottle is the standard replacement for Taylor K-2005, K-2006, K-2106, and complete FAS-DPD test kits. Keep the container tightly capped and KEEP OUT OF REACH OF CHILDREN when not actively testing pool water.
