Dynamic tests allow us to know how is the behaviour along time. It is used for viscoelastic properties of biomaterials and biological tissues.
Customer benefits
High full-scale cell load.
Target customer
Public and private research groups focused on biomaterials and tissue mechanical characterization.
Additional information
Tensile, pure shear and planar tension are the tests inside the uniaxial group. Samples are stretched along an axis by measuring force and displacement. Cycling protocols can be integrated into the mechanical test. Mechanical and viscoelastic properties can be studied. Force is measured by means of load cells.

U12-E14. Avanti J30I ultracentrifuge (Beckman Coulter)
Description:
High-speed centrifuge with aluminum rotors at fixed angle – Rotor JA-25.15 (maximum centrifugal force = 74200g, maximum speed = 25000 rpm, capacity for 24 tubes of 15 mL each, total capacity = 360 mL) – Rotor JLA-16.250 (maximum centrifugal force = 38500g, maximum speed = 16000 rpm, capacity for 6 tubes of 250 mL each, total capacity = 1500 mL) – Rotor JA-10 (maximum centrifugal force = 17700g, maximum speed = 10000 rpm, capacity for 6 tubes of 500 mL each, total capacity = 3 L)
Applications:
It allows to centrifuge samples such as emulsions, dispersions, etc at angular velocities up to 25000 rpm (74200 g) at various temperatures (from -20˚C a 40˚C), which can be used for phase separation, stability studies, etc. in colloidal systems and for the separation of cells and proteins.
U12-E13. Turbiscan-lab-backscattering-stability-analyzer-formulaction
Description:
Instrument for the evaluation of colloidal stability. It measures turbidity by multiple light scattering, as a function of time along the vertical axis by both transmitted and backscattered light. It can analyse samples up to 95 vol% with a wide range of particle sizes (10 nm – 1 mm). The samples are placed inside a temperature-controlled chamber, and the measurements can be carried out from room temperature up to 60 ˚C.
Applications:
Allows to study the colloidal stability of emulsions, suspensions and foams and to determine whether there is sedimentation, creaming, flocculation or coalescence.
U12-E12. BX51TRF6 Olympus Optical Microscope
Description:
Optical microscope that can work with transmitted or reflected light. Different observation methods can be used: bright field, dark field, phase contrast, differential interference contrast, polarized light, and fluorescence. It includes two revolvers to work at short or long distances. Moreover, it is equipped with a digital camera (Olympus DP73) connected to the computer with a software that captures images and videos.
Applications:
Observation of samples at microscale
U12-E11. DMA -46 densitometer (Anton Paar)
Description:
Instrument for the Determination of the density of liquid samples using Pulsed Excitation. It is a highly precise instrument, measuring density by the method of resonance vibration frequency of a glass capillary.
Applications:
Measurement of the density of liquid samples at controlled temperature
U12-E10. Optilab rEX Differential Refractometer
Description:
The Optilab® rEX (refractometer with EXtended range) is a Refractive Index measurement system. It has a flow cell with a total volume of only 7.4 µL. This translates into minimized band broadening and better temperature stability. It can measure the absolute refractive index of a solution. In addition, it can measure the dn/dc of a solvent at a fixed wavelength. The light source in the rEX can be replaced for other wavelengths (e.g. 690, 633, 488 nm, etc.). The temperature can be programmed from 4°C to 50°C. It is compatible with all HPLC systems.
Applications:
Refractive Index determination, mainly of liquid samples, can be useful in measurements of other techniques (Dynamic Light Scattering as an example). It can be also possible to calculate the refraction index as a function of concentration for a compound. This can allow you to determine the purity or concentration of the compound which is dissolved in a liquid.
U12-E09 Sigma 701 force tensiometer (Biolin Scientific) for the measurement of surface and interfacial tensions, wettability and critical micelar concentration
Description:
