Keng, Air and Helium Pycnometer
, Powder Technology 3 (3), 179-180 (1969).
An empty pycnometer
bottle was weighed, filled with water and reweighed.
Specific gravity of bio-oil was measured using 10-mL pycnometer
glass (ASTM International 2002).
A final confirmation of the through wall porosity was conducted by evaluating the spheres pycnometer
density before and after acid leaching.
The viscosity was determined with Ubbelohde glass capillary viscometer and density with a pycnometer
Total soil porosity was calculated from particle (Blake and Hartge 1986a) and bulk density (Blake and Hartge 1986b), which were measured using the pycnometer
method (50-mL flask) and core method (100 [cm.
After expansion, the particles were sieved to separate them by size and their density was measured using a pycnometer
Normal boiling temperatures, densities measured in a capillary pycnometer
, and refractive indices measured in an Abbe refractometer at 293.
Prices range from $5,000 for a manual gas pycnometer
to $20,000 for an automated multi-chamber model with temperature control.
Tenders are invited for Supply of Pycnometer

In addition, density was determined using a gas (nitrogen) pycnometer
(ULTRAPYC 1200e) from Quantachrome Instruments.
The physico-chemical tests and biochemical applied to different types of wheys and sweet almond oil are: pH (pH meter CG 822 GHS), lactose using the DNS method according to Miller , proteins , the Calcium content (flame photometer Jenway PEP 7), the viscosity by a falling ball viscometer (viscometer: Hoeppler BH2), the ash content by the method Afnor , the interfacial tension is determined by bidimensional Dunouy 70545, density by pycnometer
according to Hardy  and the acidity value is determined using the method described by Schnadeltach .
