Biomechanical Lab (Room D9-10)

Incubators are designed to provide precise climate control, temperature uniformity, and contamination prevention for a variety of research and clinical applications.

The 180 series is an industrial duty 150 watt unit and is compatible with all Fiber-Lite standard fiber optic and custom fiber light guides and is recommended for use in task environments which require quiet unit operation, extreme individual concentration and minimal specimen vibration transfer. The lamp is 21 volts, 150 watts, Model EKE by Ushio. The 180 is the larger and quieter version of the original 170D illuminator. Operating Instructions cover both 180 and 170D.

For very precise density measurements of small samples. The MicroMeritics AccuPyc 1330 Pycnometer is a fast, non destructive, fully automatic density analyzer that provides high-speed, high-precision volume and density measurements on a wide variety of materials. This pycnometer is a device that determines the density of small samples by actually measuring their volume very precisely. The sample mass is measured on a high quality balance and entered into the pycnometer software to give the sample density. The volume is measured using the Gas Displacement Technique. MicroMeritics describes it this way: The AccuPyc works by measuring the amount of displaced gas [helium]. The pressures observed upon filling the sample chamber and then discharging it into a second empty chamber allow computation of the sample solid phase volume. Gas molecules rapidly fill the tiniest pores of the sample; only the truly solid phase of the sample displaces the gas.

The UV aging testing machine is used to simulate the damage of the sunlight, rain, and dew to the non-metal materials which is widely used in the industry such as rubber, printing ink, plastic, paint, packaging, medical and so on. It is used to evaluate the color change overtime on dental composites.

The device simulates various brushing movements on the surfaces of teeth and material specimen. A maximum of 10 specimens are simultaneously exposed to abrasion in the tooth brushing machine. Each specimen may be different in form and material (hardness), and may be loaded with various levels of contact pressure. The specimen chambers are separated from each other so that each specimen can be operated with its own liquid (e.g. toothpaste-water mix), and individually cleaned. All the brushes are controlled by a central drive system, and the chosen type of movement is therefore the same for all specimens used in the test. A high-grade motion controller guarantees exact speeds and trajectories which can be adjusted with a very high degree of precision. The motion sequence (teeth cleaning technique) can be freely selected from a combination of forwards, backwards and circular movements. Complex motion sequences can be easily programmed by means of an optional software module.

The device simulates various chewing movements in the mouth for materials testing of implants, bridges, crowns, composite material and jaw models: Execution of complete chewing cycles by means of linear 2-axis motion; Interpolated circular dual-axis movement for higher simulation frequencies up to 5Hz; Simulation of Bruxism especially to test bite splints; Integrated real-time wear analysis with break detection for every sample station (option); The functional principle of the CS-4 device set standards in pre-clinical screening of material since 1998 but could be further improved and adapted to our customers' wishes:; Kinematics: Particularly precise motion through the use of digital servo drives; Significantly reduced noise when running, so can be used without problems in laboratories; 2-axis operation reduces test times by up to 20% by means of simultaneous reverse motion along both axes; Devices available which have identical specifications but 2 or 4 specimen chambers. This gives; significant price advantages for users with smaller specimen volumes; Various specimen holders, antagonists and special test rigs are available.
