U13-E02. Machines for mechanical tests

Machines for mechanical tests:

• Instron MicroTester 5848 and 5548: electromechanical machines for displacement or load control tests:

•• load range from 1mN to 2kN at full scale.
•• load cells of:+/- 5, 50, 500 and 1000N.
•• synchronous data capture in all the channels up to
500 Hz.
• Biaxial Instron MicroTester 8874: axial-torsional, servohydraulic testing machine:
•• load capacity of 25 kN and 100 Nm.
•• fatigue tests at a low number of cycles.

›› Software for data control and analysis.
›› Accessories and tools especially designed by the group, which allow a wide flexibility in designing tests, allowing the verification and/or validation of theoretical models.
›› AVE video extensometer connected to the machines; resolution of 0.5 μm. To determine the axial and transverse deformation without contact (tension, dynamic properties and viscoelasticity) of the samples.

• E1000 Test Instrument: Dynamic systems to offer slow-speed static testing and high-frequency dynamic fatigue testing with hundreds of Hertz capability: Load range: 250 N to 2.0 KN.
• Nano BIONIX MTS: For nanomechanical characterization of biomaterials. Load range to 0.001N to 0.5N.

U13-E01. MicroCT GE eXplore Locus SP (GE)

MicroCT GE eXplore Locus SP (GE): Computed X-ray Axial Tomograph for the non-destructive study of the microstructure and in vitro tomography: ›› Samples of up to 40 mm in diameter; resolution of 10 μm. ›› Different types of tissues, implants, scaffolds, etc. ›› Complete “section-by-section” imaging with a single rotation (cone beam volumetric technology); excellent image quality and “signal-to-noise” ratio. ›› “Bone Analysis Tool” software provided with: •• BMD (Bone Mineral Density): It calculates the density of minerals in the bone, the bone volume fraction and the mineral content in the bone. •• Anisotropy: It determines the degree of symmetry and the orientation of the trabecular structure. •• Cortical Analysis: It determines “section-by-section” the width, surface area and the BMD value of the cortical bone. •• Stereology: It provides the bone volume fraction, the ratio between the surface of the bone and its volume and the width of the trabecular plate. •• Direct Measures: It determines the local trabecular width of a bone and allows obtaining a visual representation of this local width.

U12-E14. Avanti J30I ultracentrifuge (Beckman Coulter)

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)

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.
