Buffer Solution, pH 1.0, Reference Standard (1 per EA )

Buffer Solution, pH 13.0, Reference Standard (1 per EA )

Buffer Solution, pH 2.00 +/- 0.02 @ 25 DEG C, Reference Standard is a mixture of weak acid and its conjugate base in order to prevent changes in the pH of a solution. Buffer solutions let you calibrate any pH tester to ensure accurate readings when measuring pH in water samples and process liquids.

Red-Four (TM) Buffer Solution, pH 4.01 +/- 0.01 @ 25 DEG C, Color-coded RED, Reference Standard (1 per EA )

Buffer Solution, pH 1.68 +/- 0.02 @ 25 DEG C, Reference Standard is an inorganic solution in water. Spectrum solutions utilize the highest quality raw materials appropriate to your product. Most raw materials meet or exceed the specifications established by the American Chemical Society. Where appropriate, many finished products are traceable to NIST Standard Reference Materials. Manufacturing, quality control testing, and packaging are all performed in Spectrum's own facilities. Record keeping and sample retention of all produced lots ensure product consistency and complete traceability.
