You have a favorite pipette.  Familiarity with the electronic interface makes its use second nature. Maybe your hand fits it just right, or the smoothness of the action makes it easy to use. Then, one day, your dispensed volume just feels “off”.  You try pipetting the liquid again, and again it looks too low or too high. What can you do? Basic pipette testing verifies the accuracy – or inaccuracy – of your equipment. Fortunately,

What Is A Pipette?

A simple, critical, instrument in labs across the world, a pipette transports a measured volume of liquid safely and accurately.  Pipettes can be as simple as plastic tubes and as complex as precise electronic devices.  They generally have a single channel, eight (8) channels, or twelve (12) channels. Dr. Heinrich Schnitger, from Marburg, Germany, invented the first micropipette in 1957. This model measured and transported a fixed amount. Later, the co-founder of biotechnology company Eppendorf,
What Is a Super-Thermometer? Metrology laboratories around the world rely on super-thermometers for their reliably accurate, easy-to-take measurements.  For instance, the Hart Scientific 1590 Super-Thermometer II reads accurately to 0.00025°C or 1 ppm. This high degree of accuracy makes super-thermometers perfect for calibration of SPRTs (Standard Platinum Resistance Thermometers). Further, they are the best lab instruments to take advantage of SPRT accuracy. They read temperature directly, automate data collection, and calculate constants for ITS-90. Additionally,
When employing thermometer calibration by the Comparison Method, readings from a thermometer with unknown accuracy are compared to those from a standard device. The standard device is calibrated to meet the quality requirements of the National Institute of Standards and Technology (NIST) or a similar governing body. Typically, this method of calibration is used for liquid-in-glass thermometers. This technique often applies to Standard platinum resistance thermometers (SPRT) and resistance temperature detectors (RTD) for industrial equipment
