Pycnometers according to Guy Lussac for measuring the density of liquids can be found in our online shop. Each pycnometer is supplied with a stopper and thermometer. Furthermore, BRAND offers sedimentation vessels according to Imhoff made of gas and plastic as well as oxygen bottles according to Winkler for the determination of oxygen dissolved in water.
BLAUBRAND® density bottles are individually adjusted. The nominal capacity specified to 0.001 cm3 is indelibly engraved on each bottle. Each bottle is calibrated with its own stopper or thermometer, hence, stoppers and thermometers are not interchangeable. Each bottle and its stopper or thermometer is marked with a unique matching identification number. All BLAUBRAND® pycnometers are supplied with the following certification: in quantity with an individual certificate, upon request with a DAkkS Calibration Certificate (from a DAkkS-accredited calibration laboratory at BRAND). Density bottle, uncalibrated: Borosilicate glass 3.3. DIN ISO 3507. Stopper NS 10/19 with capillary. Top of stopper ground and polished. Nominal capacity printed on the bottom. Density bottle, calibrated: Borosilicate glass 3.3. DIN ISO 3507, Gay-Lussac type. Calibrated to contain (TC, In). Reference temperature 20 °C. Individual certificate included. Stopper NS 10/19 with capillary. Top of stopper ground and polished. The volume in cm3 is specified to a precision of 3 decimal places.
Oxygen flask, Winkler pattern: Soda-lime glass. For the determination of oxygen dis-solved in water. Capacity is calibrated to ± 0.01 ml and engraved on the flask. White labelling area. Solid, obliquely cut standard-ground glass stopper can be secured with a fastening clip. Each flask is calibrated with its own stopper, hence, stoppers and flasks are not interchangeable. Each flask and its stopper is marked with a unique matching identification number. Graduated to 1000 ml Borosilicate glass 3.3 DIN 12672 without stopcock.
