The Biomedical Engineering Shared Laboratories are a collection of controlled access labs that house various equipment shared amongst the biomedical engineering faculty. The main purpose of these facilities is to provide more cost-effective resources for the research groups and to minimize duplication of equipment within the department. User fees for the equipment are assigned on a cost-recovery basis. Equipment training is required prior to use and gaining lab access. Equipment is available to other Texas A&M University departments and external users, however priority is given to biomedical engineering students.

The instron allows for mechanical testing of samples using 1000N load cell to test compression and tension.

A lyophilizer is a benchtop freeze dryer used to freeze the material and reduce the surrounding pressure so that the frozen water will sublimate from solid phase to gas phase. This is most often used in samples that will be imaged under SEM and need to preserve their structure.

Microtome

A microtome is a tool used to cut extremely thin slices of material.

NanoDrop OneC

Microvolume UV-VIS spectrophotometer that can quantify and qualify DNA, RNA and protein samples in seconds with only 1-2 µL, and obtain full-spectral data. This equipment also has a cuvette option.

Plate readers are used for common detection of absorbance, fluorescence intensity, luminescence, time-­‐resolved fluorescence and fluorescence polarization of samples in well plates.

QCM

The quartz crystal microbalance measures the frequency and mass of a sample. The crystal has a certain frequency and as proteins stick to the crystal they will change this value which will correlate to the mass.

Rheometers are used to find stress, strain, modulus or viscosity data using a cone and plate with set parameters such as shear, temperature, oscillation, etc.

In a Scanning Electron Microscope, the surface of a specimen is scanned by a beam of electrons that are reflected by a secondary or backscattered detector to form an image.

Slide scanners digitalize slide images to scan, view and share on a cloud server.
