Receive stable readings to 0.01 pH in less than 30 seconds with the Thermo Scientific Orion 8103BN ROSS Combination Semi-micro pH Electrode. Results are three to five times more precise than those obtained with conventional electrodes.

• Works in extreme case of samples varying from one another by 50°C or more
• Drift is less than 0.002 pH per day, restandardization is minimized
• Fits test tubes, measures samples as small as 0.2mL
• Semi micro tip
• Cap diameter: 16mm

Includes

• One 60mL botlle of filling solution, Orion Cat. No. 810007

Storage Requirements

To ensure a quick response and free flowing junction, the sensing bulb and reference junction must not dry out. Short-term Storage (up to one week): Soak the electrode in ROSS’ pH electrode storage solution, Cat. No. 810001. Long Term Storage (more than one week): Fill the reference chamber and securely cover the fill hole. Cover the sensing bulb and reference junction with the protective cap, sleeve or storage bottle containing a few drops of storage solution.
