Introducing Bartek’s pH & Acid Calculator

A free, browser-based tool that lets formulation teams build, compare, and optimize acid systems in real-time—no install, no setup, no math by hand.

Why we built it

Every formulator knows the loop: tweak the acid, run the bench, measure the pH, adjust again. It’s reliable, but it’s slow—and when you’re juggling multiple acidulants, target pH ranges, and downstream stability, the spreadsheet you started with is rarely the spreadsheet you finish with.

We built the Formulation Calculator to shorten that loop. It’s a free, browser-based tool that lets formulation teams build, compare, and optimize acid systems in real time—no install, no setup, no math by hand.

What it does

  • By Acid — Choose your acidulants and amounts; the tool predicts the resulting pH.
  • By Target pH — Tell it the pH you need; the tool back-solves the acid load.

In both modes you can:

  • By Acid — Choose your acidulants and amounts; the tool predicts the resulting pH.
  • Model seven acidulants, including citric, malic, fumaric, lactic, tartaric, acetic, and phosphoric
  • Run citric–malic blends and other custom combinations side-by-side
  • Add an optional buffer to fine-tune behavior near your target
  • Compare multiple formulations on one screen and see the acid profile that’s driving each result

Who it’s for

The calculator is built for R&D and product development teams across the applications Bartek serves every day: Food & Beverage, Animal Nutrition, Industrial, Pharma, and Personal Care. Whether you’re matching a benchmark, reducing a single ingredient, or scoping a new SKU, it’s designed to help you reason about acid systems before you commit bench time.

From the lab to the line

By front-loading the “what if” questions into a fast, visual model, formulators can:

  • Cut the number of trial iterations needed to land a target pH
  • Document the scenarios they evaluated, not just the one they chose
  • Share clear acid profiles with cross-functional partners in regulatory, procurement, and application

It’s a small tool, but it reflects how Bartek thinks about formulation: fewer guesses, more certainty, faster to market.
