Carrying full bottles of calibration and storage solution isn't practical for growers who need to check or maintain probes away from the main setup. The Bluelab Solution Sachet 30 Box solves this with single-use, quick tear-open sachets sized for on-the-go calibration and probe storage, keeping your Bluelab pH Pen or Conductivity Pen accurate wherever you're working.
Each box contains 30 individual 18ml (0.6fl.oz.) sachets, easy to open and use in a single application without measuring or risk of contamination from a shared bottle. Choose the single-solution box that matches your routine, or the Mixed box for a ready-made assortment covering full 2-point pH calibration plus EC and storage needs.
Each box contains 30x 18ml (0.6fl.oz.) tear-open sachets.
Compact, single-application sachets fit easily in any kit or pocket.
Select a single solution type or a ready-made Mixed assortment box.

A single-type box gives you 30 sachets of one solution, while the Mixed box provides a assortment of 10x pH 4.0, 10x pH 7.0, 5x 2.77 EC, and 5x KCl Storage sachets in one box.
Each sachet contains 18ml (0.6fl.oz.), sized for a single calibration, storage, or accuracy check.
No. They're single-use, designed to be torn open and used once, avoiding contamination risk from a shared bottle.
If you only need pH calibration, choose the pH 4.0 and pH 7.0 boxes to cover standard 2-point calibration, or the Mixed box if you also want EC and storage sachets on hand.
Yes. Their compact, quick tear-open design makes them well suited for calibration or probe storage away from your main setup.
