The Hydrion Chemvelope HASs a triple protection of foil, polyethylene and paper which keeps the enclosed buffer dry and free flowing. The envelope is clearly marked with the correct pH value. The contents of the chemvelope, when dissolved in 500mL of distilled water, makes a precise buffer solution. Packaged five envelopes to the box and supplied with one dispenser vial of hydrion color key buffer.
