The picture above shows how pH is measured in a droplet (4 µl) of dissolved drug. Instead of raising volume, I recommend lowering on the other tabs and raising system volume… No need for a beaker to calibrate your meter or measure a sample. The pH-4 micro is a multi-channel pH meter used with micro-invasive sensors based on a 140 μm optical fiber. Use with the Thermo Scientific™ Orion™ Versa Star™ LogR™ Meter to take pH and temperature measurements utilizing LogR technology. Measurements in small volumes of liquid (> 4 µl) Due to the extremely small dimensions of the microsensors (down to 3 µ m), they are suitable for measuring in very small sample volumes down to a few microlitres. Low dead volume. It is connected to a PC and controlled with an easy-to-use software. Limited Time Sale Easy Return. One of the most important factors to evaluate when selecting a soil moisture sensor is the volume of soil that the sensor integrates into the volumetric water content (VWC) measurement. Top Pick! No need for reference electrodes - a real step forward, especially in small volumes. In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases and Lewis bases.All definitions agree that bases are substances which react with acids as originally proposed by G.-F. Rouelle in the mid-18th century.. Svante Arrhenius proposed in 1884 that a base is a substance which dissociates in aqueous solution to form hydroxide ions OH −. A silver wire in this solution forms a silver/silver chloride inner-reference electrode, which is connected to one of the terminals of the potential-measuring device, pH-meter. A small volume of hydrochloric acid saturated with silver chloride is contained in the tube. The calomel electrode is connected to the other terminal.
