An ophthalmic, line-powered, measuring instrument used for determining the intraocular pressure (IOP) by exerting an external force against the eye which provides a reading of the resistance of the tunica of the eye to deformation (the extent of corneal ind...
An electrically-powered, ophthalmic device designed to be used by a healthcare professional to objectively measure the refractive error of the eye (the inaccuracies of focusing light upon the retina) by measuring how light is changed when it enters the pati...
A tabletop- or bench-mounted mains electricity (AC-powered) device used mainly in the clinical laboratory to process through high-speed centrifugal force (typically 10,000 to 25,000 rpm) specimens of whole blood to determine the ratio of the red cell volume...
An ophthalmic, battery-powered, measuring instrument designed for determining the intraocular pressure (IOP) by exerting an external force against the eye which provides a reading of the resistance of the tunica of the eye to deformation (the extent of corn...
An electrically-powered, automated, ophthalmic device designed to measure the refractive error of the eye (the inaccuracies of focusing of light upon the retina) by measuring how light is changed when it enters the patient's eye(s). A beam of light is emitt...
A non-powered, hand-held manual ophthalmic instrument intended to be used to apply pressure to the lower eyelid to facilitate natural release and/or expression of meibomian gland secretions (meibum) for diagnostic evaluation during a routine eye examination...
An electrically-powered device intended to be used for the processing of whole blood specimens using centrifugal force to determine the haematocrit, i.e., the ratio of red blood cell volume to whole blood volume expressed as a decimal, fraction, or percenta...
A hand-held, battery-powered device intended to imitate a variety of physiological parameters and a variety of conditions (both foetal and maternal) expressed during pregnancy (e.g., TOCO, uterine and foetal heart activity) in order to test and calibrate fo...
