Osmometers

Definition : Clinical laboratory measuring instruments designed to determine a solution's osmotic pressure, a variable related to the particle concentration (i.e., osmolality) of an aqueous solution such as body fluid, including whole blood, plasma, serum, and urine. These readings are used to determine levels of solute concentrations that control the movement of solutes throughout body tissues. Two main types of osmometers (freezing point and vapor-pressure osmometers) intended to measure small-particle osmolality (i.e., crystalloids such as glucose or urea, ions such as sodium or chlorine) are available; osmometers intended to measure osmolality due to molecules of a greater mass (i.e., colloids) and particles with a mass greater than 30,000 atomic mass units (i.e., Daltons) such as serum proteins are also available (i.e., colloid osmometers, also known as oncometers). An abnormal ratio between the osmolality values for urine and serum can indicate renal disease, diabetes insipidus, or secretion of abnormal levels of antidiuretic hormone; water and electrolyte imbalances are also present in patients with acute poisoning and shock trauma.

Capitol Scientific Inc

Capitol Scientific was originally formed and incorporated in Austin, Texas in November 1963 as Chem Products, Inc. At that time the founding principals were Lee A. Williams and Mack Johnson. The purpose being to manufacture n-Methyl-Piperazine; a product used in the manufacture of the original anti-histamines in the pharmaceutical market. Chem Products had an excellent product but was unable to produce in sufficient quantities to make a profit, and sold the rights to their manufacturing process.
