A tensile tester, also known as a pull tester or universal testing machine (UTM), is an electromechanical test system that applies a tensile (pull) force to a material to determine the tensile strength and deformation behavior until break.

A typical tensile testing machine consists of a load cell, crosshead, extensometer, specimen grips, electronics, and a drive system. It is controlled by testing software used to define machine and safety settings, and store test parameters defined by testing standards such as ASTM and ISO. The amount of force applied to the machine and the elongation of the specimen are recorded throughout the test. Measuring the force required to stretch or elongate a material to the point of permanent deformation or break helps designers and manufacturers predict how materials will perform when implemented for their intended purpose.

Fluorescent microscopy is often used to image specific features of small specimens such as microbes. It is also used to visually enhance 3-D features at small scales. This can be accomplished by attaching fluorescent tags to anti-bodies that in turn attach to targeted features, or by staining in a less specific manner.

Optical microscopy is used extensively in microelectronics, nanophysics, biotechnology, pharmaceutic research, mineralogy and microbiology. Optical microscopy is used for medical diagnosis, the field being termed histopathology when dealing with tissues, or in smear tests on free cells or tissue fragments.

It is an easy-to-use, stand-alone instrument for measuring viscosity and yield stress. Rheometers are supplied with an internal spring used to calculate the viscosity of a material. These springs have different measuring capabilities:

LV is for low viscosity materials and can measure the thinnest materials. Typical examples include inks, oils, and solvents.RV is for medium viscosity materials than those measured with an LV torque. Typical examples include creams, food, and paints.HA is for higher viscosity materials than those measured with an RV torque. Typical examples include gels, chocolate and epoxies.HB is for even higher viscosity materials than those measured with an HA torque spring. Typical examples include asphalt, caulking compounds, and molasses.

Small-angle X-ray scattering (SAXS) is used to measure the elastic scattering from a material over an angular range of ca. 0.05 – 5°. These scattering profiles can be used to determine information about the sizes and shapes of these structures as well as the average distance between them.

The CryoMill is designed to use liquid nitrogen for cryo-grinding. Before and during the grinding process, the grinding jar is continuously refrigerated with liquid nitrogen from the integrated cooling device. The sample is thus embrittled and volatiles are prevented from escaping. Liquid nitrogen circulates through the unit and is constantly replenished by an Autofill system in the exact amount required to retain the temperature at -196 °C. Strong impact ball milling results in flawless grinding efficiency. Autofill prevents direct contact with LN2 and makes cryogenic grinding very clean. Its flexibility (cryogenic, wet and dry grinding at room temperature) makes CryoMill an ideal grinder for amounts of up to 20 ml.

The dryer works by heating up air while removing moisture, using desiccants, and then forces the air through the pellets in the hopper. The movement of the hot air wicks the moisture back to the base of the machine and the pellets are dried with ease.
