Used THERMO SCIENTIFIC F01981 #293667220 for sale

THERMO SCIENTIFIC F01981 is a multifunctional laboratory device used to measure the physical properties of biological samples such as pH, temperature and ionic activity. The device is a multi-parameter probe which is capable of measuring and analyzing a variety of physical parameters. The device is composed of a metallic casing, an LED display and a rotary switch for sensitivity adjustment. The device has an active element which consists of a high sensitivity Peltier thermocouple. A sample can be placed in the chamber and the temperature of the sample is monitored by the thermocouple. The device offers a variety of temperature units including Celsius, Fahrenheit and Kelvin scales. Additionally, the device is capable of automatically measuring and recording temperature variations of a sample over time. The device also includes a dedicated pH probe which is capable of accurately measuring the pH of biological samples. The pH probe consists of a platinum-iridium electrode which has a very fast response time. The pH measurements obtained are automatically recorded in the LED display. The pH electrode is also equipped with a built-in reference electrode which helps to keep the electrode moist and protected from corrosion. The device also measures the ionic activity of a sample. This quantifies the number of ions present the sample and is used to identify the presence of inorganic or organic molecules in solution. The ionic activity of a sample can be accurately measured and monitored using the IonSelect electrode. This electrode consists of an alloy of chloranil and platinum and is capable of providing accurate readings of ionic activity. The device is easy to use and setup. It is designed to be user friendly and includes basic instructions which outline the process for measuring physical properties of a sample. The device also includes various accessories such as a lab stand, a sample holder and a power cord which are essential in order to provide an optimal performance. Finally, F01981 is an excellent choice for accurately measuring and monitoring the physical properties of biological samples in a laboratory setting. The device offers a wide range of accurate and reliable measurements with a quick response time. Moreover, the presence of both temperature and pH probes, as well as the IonSelect electrode, allows the device to measure a wide range of physical properties of a sample.
