Esophageal stethoscopes with temperature sensor is used for accurately monitoring core temperature and heart and breath sounds. These are placed into the esophagus to provide accurate measurement of a patient's core body temperature and transmit heart and lung sounds to the anesthesiologist's earpiece.

Esthesiometer is an instrument used to measure tactile sensitivity of the skin. The measure of the degree of tactile sensitivity is called aesthesiometry. There are different types of esthesiometers depending on their particular function. The simplest is a manual tool with adjustable points similar to a caliper. It can find out how short a distance between two impressions on the skin can be distinguished.

Estradiol is the most potent estrogen of a group of endogenous estrogen steroids, which includes estrone and estriol. It is the most active form of estrogen in the human body. An estradiol test measures the amount of estradiol in the blood. This test is used to evaluate function of the ovaries, placenta, or adrenal glands, particularly when certain types of ovarian tumor are suspected, or when there is delayed or abnormal development of male or female body characteristics.

Estradiol ELISA Kit is a solid phase enzyme-linked immunosorbent assay based on the principle of competitive binding.

Blood gas safety syringe protects technicians from needle stick injuries. It has an attached seal to prevent air contamination of the sample. The needle is advanced just prior to sample withdrawal. The sample is taken. By simply withdrawing the syringe within the guard, the needle is locked and the sample sealed. This step can be performed with one hand while pressure is applied to the puncture site.

Estrone is an estrogenic hormone. It is produced primarily from androstenedione originating from the gonads or the adrenal cortex. It is relevant to health and disease due to its conversion to estrone sulfate, a long-lived derivative of estrone. It is a primary estrogenic component of several pharmaceutical preparations, including those containing conjugated and esterified estrogens.
