Auxanometer – Laboratory Equipment An auxanometer is an apparatus for measuring increase or rate of growth in plants. In case of an arc-auxanometer there is a wire fixed with the plant apex on one end and a dead-weight on the other. It passes over a pulley which has a pointer attached to it. When the plant’s height increases, the pulley … Continue reading “Auxanometer”
A special mercury-in-glass thermometer with high precision(1/100o) in a small range that can be selected from a very wide range(-20 to 180o). A Beckmann thermometer is a device used to measure small differences of temperature, but not absolute temperature values. It was invented by Ernst Otto Beckmann (1853 – 1923), a German chemist, for his … Continue reading “Beckmann Thermometer”
