YUCHENGTECH Paint Density Specific Gravity Cup Stainless Steel Paint Density Determiner Pycnometer Coating Specific Gravity Cup(100ml)

Description: The Specific Density Cup is also called the Liquid Pycnometer, it is used for quality control.The Coating Specific Gravity Cup is designed in a cylindrical shape which provides a large opening for easy filling, emptying, and cleaning.The tightly fitted stainless steel covers have a small hole in the center to allow excess sample material to be expelled without entrapping air bubbles, which increases accuracy.Technical parameters: 1.100ml volumetric ISO standard size, 50ml specific volume, 37ml volumetric GB standard size, ensures error within 1 mg (0.001%).2.Test is carried out in 23℃±2℃, in accordance with ISO standards.3.The corrosion resistance of stainless steel.How to use a Density Cup:1.Weigh cleaned density cup empty and record weight2.Temper density cup and test liquid (20°C±0.5°C/68°F±1.0°F)3.load the liquid into density cup4.Put cover on without tilting to avoid air bubbles5.Remove overflowing liquid carefully with absorbent cloth6.Weigh filled density cup7.Calculate densityCalculation method: ρ=(m2 - m1) / V m1= the weight of cup (g)m2= the total weight of cups and sample (g)V= volume of the cup (ml)Care of density cups:With the exception of a daily cleaning, density cups are essentially maintenance free.If it is expected that a cup will be stored for an extended period of time, it is recommended that it be given a light coating of protective oil.With only these precautions, the cup should provide long and satisfactory service and retain its original attractive appearance.'
