TENS Tester is used for checking the conductivity of lead wires or the output of the electrical stimulator.

Tens unit electrodes feature ultra-flexible construction as well as tan-tone fabric for reduced visibility. These pin connector polymer-gel electrodes are ideal for TENS applications as well as NMES for small muscle groups.

Terrific broth is used with glycerol in cultivating recombinant strains of Escherichia coli. It is a highly enriched medium developed to improve yield in plasmid-bearing E. coli. Recombinant strains have an extended growth phase in the medium. The addition of extra peptone and yeast extract in the medium allows higher plasmid yield per volume. Glycerol is used as the carbohydrate source in this formulation.

Electronic Test Equipment is used to create stimulus signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced and repaired. Practical electronics engineering and assembly requires the use of many different kinds of electronic test equipment ranging from the very simple and inexpensive such as a test light consisting of just a light bulb and a test lead to extremely complex and sophisticated such as automatic test equipment. Biomedical devices are materials that interact with biological systems to replace, improve or repair specified physiological conditions. Although often used for medical applications, biomedical products also describes many other elements, including fermentation-produced enzymes and pharmaceutical products, diagnostics and novel biomaterials. 

Test Tube is a piece of laboratory glassware composed of a finger-like length of glass tubing, open at the top with a rounded U-shaped bottom. Test tubes are available in a multitude of lengths and widths to serve a varying number of needs. Test tubes are constructed of expansion-resistant glasses such as Pyrex and held in a flame such as that produced by a bunsen burner. Test tubes are made from plastics are formed using injection molding.

Testosterone is a steroid hormone from the androgen group. It is primarily secreted in the testes of males and the ovaries of females although small amounts are secreted by the adrenal glands. A testosterone test measures the amount of testosterone in the blood. This test is performed when symptoms indicate there may be abnormal androgen (male hormone) production.
