Glass, because it is chemically and biologically inert and resistant to high temperatures, is an ideal material for the manufacture of glass beads, stopcocks and specialty glass labware. Unlike plastic, glass is much easier to sterilize, allowing glass labware to be reused. Glass beads, manufactured from borosilicate glass that is resistant to high temperatures and thermal shock, are resistant to liquid or vapor attack, while stopcocks manufactured from glass feature either a plastic plug that does not require grease for turning or a glass plug that does but is more effective for high vacuum work.
Designed for measuring and comparing the densities or specific gravities of liquids and solids. This non-mercury spirit-filled pycnometer is supplied with Standard Taper 10/18 thermometer with a range of 14 to 38°C in 0.2° increments.
Provides distillations for nitrogen determination. Labconco™ RapidStill I™ Unit is designed for labs that are determining micro quantities of protein/nitrogen or performing one or two macro determinations per day by diluting and aliquoting the sample.
