Alkalinity-P Powder Pillows

Overview

Alkalinity-P powder pillows measure P alkalinity, the portion read to the phenolphthalein end point that covers carbonate and hydroxide. It is the figure used on boiler water and lime-softened supplies, where the split between P and M alkalinity shows which species are present.

Key features

• Reads the phenolphthalein (P) alkalinity, not the total M figure
• Pre-measured sachets, so nothing has to be weighed out on the bench
• Sealed individually, which keeps the reagent dry and the dose consistent
• Supplied in the 100-pillow pack, item code PPHAPB100

Frequently asked questions

When would I measure P alkalinity instead of M?
When you need to know how much of the alkalinity is carbonate and hydroxide, typically on boiler water or after lime dosing. Routine potable and pool work uses the M value.

Why use powder pillows instead of tablets?
A pillow is a pre-measured dose in a sealed sachet, so there is nothing to weigh out and no part-used tablet strip. Where a method is only offered in powder form, the pillow is what the instrument expects.

How should powder pillows be stored?
Keep them cool and dry in their sealed sachets, work through the oldest box first, and open a pillow only at the moment you dose the sample.
