If an osmometer
containing a sugar solution (graphic) is placed in a container of pure water, the solute in the osmometer
is unable to pass through the semipermeable membrane.
Osmolality of the samples was determined in Advanced Instruments osmometer
(Needham Heights, MA).
The salinity of the seawater in each tank was established using a refractometer, and its osmotic concentration was measured with a vapor pressure osmometer
Density was measured by weighing 1 mL of plasma or serum, and osmolality was measured with an Advanced Osmometer
3D3 (Advanced Instruments).
Leaf osmotic potentials of stressed ([[Psi].sub.[Pi]0]) and fully rehydrated ([[Psi].sub.[Pi]100]) leaves were measured using a vapor pressure osmometer
(Wescor, Inc., Logan, UT).
295, 285, 275, 265 and 255 mOsm/Kg with bi-distilled water using an osmometer
(Osmomat 030, Gonotec Berlin, Germany).
The fully automated, multi-sample A20 Advanced Automated Osmometer
includes a touch-screen user interface with a menu-driven operating system, intuitive software control, and multi-language capability.
Plasma total protein concentration and osmolality were measured using a refractometer (Atago, Tokyo) and an osmometer
(OM-6010, Kyoto Daiichi Kagaku, Kyoto), respectively.
Osmotic pressure was measured with micro osmometer
by calibrating the equipment in m.osmolkg-1 of water.
Hemolymph (50 [micro]1) was removed repeatedly from individual lobsters at 0, 30, 60, and 120 min of exposure to 50, 100, or 150% seawater (n = 4 for each time point), and osmolarity was measured with a vapor pressure osmometer
Osmotic potential ([[Psi].sub.[Pi]]) was measured with a vapor pressure osmometer
(Wescor, Inc., Logan, UT) after cell saps was expressed from frozen leaves with a hydraulic press.
is a precise and reliable system for the measurement of the average molecular weight Mn of polymers, soluble in aqueous or organic solvents.
