A speculum is a medical tool used for examining body cavities, with a form dependent on the body cavity for which it is designed. A vaginal speculum consists of a hollow cylinder with a rounded end that is divided into two hinged parts, somewhat like the beak of a duck. The speculum is inserted into the vagina to dilate it for examination of the vagina and cervix. Ear speculum resembles a funnel, and come in a variety of sizes. Nasal speculum has two relatively flat blades with handle. The instrument is hinged so that when the handles are squeezed together the blades spread laterally, allowing examination.

Sphygmomanometer is a device used to measure blood pressure, comprising an inflatable cuff to restrict blood flow and a mercury or mechanical manometer to measure the pressure. This is an instrument used for determining arterial blood pressure indirectly. A sphygmomanometer consists of a hand bulb pump, a unit that displays the blood pressure reading and an inflatable cuff that is usually wrapped around a persons upper arm.

Spin tissue processor is a compact, bench top semi-enclosed carousel tissue processor. It is designed to process biological specimens from chemical fixation to paraffin infiltration.

Spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. It is a precision differential pressure transducer for the measurements of respiration flow rates. The spirometer records the amount of air & the rate of air that is breathed in and out over a specified time.

A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. It is a precision differential pressure transducer for the measurements of respiration flow rates. The spirometer records the amount of air and the rate of air that is breathed in and out over a specified time. The evaluation of lung function with a spirometer, is one of the simplest, most common pulmonary function tests and may be necessary for any/all of the following reasons: to determine how well the lungs receive, hold, and utilize air, to monitor a lung disease, to monitor the effectiveness of treatment and to determine the severity of a lung disease.

Incentive Breathing Exerciser includes an inner bellows whose deflection allows accurate measurement of the initial volume of air inhaled by a patient and an outer bellows for measuring larger volumes of air after a valve in the inner bellows opens.

Spirometer is a device used by physician that assesses lung function. Spirometer is a most common pulmonary function tests. It determines how well the lungs receive, hold & utilize air. It is used to monitor a lung disease, effectiveness of treatment and to determine the severity of a lung disease.

A steam sterilizer is a piece of equipment made up of many parts that, when combined together, allow saturated steam to contact the items within the chamber to effect microbial kill. The design of a steam sterilizer can range from a small, manually operated tabletop sterilizer to a large, computer-controlled floor-loading model. It consists of a chamber to hold the goods to be sterilized along with the controls to effect the intended process.

Stem cell bank stores ethically-approved, quality-controlled stem cell lines derived from adult, fetal and embryonic tissues.

Stereomicroscopes use external lighting and are effective in the range of 6 x to 150 x magnification. Stereomicroscopes are used to scan large carriers of trace evidence such as clothing, for fibers, gunpowder particles and specks of blood.
