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.
