  5. How To Test Your EVOM2 Meter
    April 24, 2013
    The World Precision Instruments (WPI) EVOM2is used for making trans epithelial electrical resistance (or TEER) measurements. We recommend that you test your EVOM2 before you use it for the first time and then periodically after that. If there is a concern that the meter or the electrode is not functioning properly, test the meter first. This video shows how to test the meter. More Info
  6. Microsquisher at Work with Stem Cell Aggregates
    April 24, 2013
    The following video shows how Dr. Todd McDevitt's laboratory at Georgia Tech is using the CellScale Microsquisher on stem cell aggregates. The MicroSquisher is designed to perform compression testing on specimens between 50µm and 2mm with force resolutions as small as 50nN. Forces are determined from the deflection of a flexible cantilever beam to which one compression plate is attached. Displacement control is achieved by manipulating the base of that beam using a motorized piezo stage.      More Info WPI is the exclusive North American distributor for Cell Scale.

  7. EVOM2-How to Equilibrate Your STX2
    April 24, 2013
    The World Precision Instruments (WPI) EVOM2 is used for making trans epithelial electrical resistance (or TEER) measurements. Two silver/silver chloride pellets are used for the electrodes. The chloride ion tends to migrate, which is a reversible reaction. But, because of this chloride ion swapping, the electrodes need to be polarized before each use. Before using the meter for making voltage measurements, equilibrate the electrodes. This video shows you how.   More Info
  8. Selecting the Correct Tip for Your NanoFil Microinjection Application
    April 24, 2013
    Specially designed tips as small as 36 gauge (110 micron OD) are offered in both blunt and beveled styles. Our studies have shown that these tips will cause less trauma to the tissue than any other form of micro syringe currently in use. NanoFil has a unique coupling mechanism that allows many different forms of small tubing and tips to be coupled with the syringe barrel. Configurations Based on application requirements, NanoFil can be used in several different configurations. Direct Microinjection by Hand This is the simplest and most economical way to inject. Any of our tips can be inserted directly into the NanoFil
  9. INs and OUTs of Surgical Needles for Suturing
    April 24, 2013
    Surgical needles are specifically designed for their application. The diagram below shows the difference between cutting edge and taper point needles. Cutting edge needles have sharp edges that penetrate easily through tough tissue. They are ideal for suturing skin and dense dermal tissue.    Taper point needles pierce and spread tissue without cutting it. They are ideal for suturing delicate, soft tissue when minimal trauma is desired.
  10. SI-H Cell Tester Opens a New Window to Cellular Studies
    April 24, 2013
    New technologies developed by SI-H offer incredible opportunities for muscle physiology researchers. Up until now, many studies required an entire day to perform a single trial. Now, after isolating the cells, these same studies can be run on single cells in a matter of minutes. Because we are working on single cells, we can test living organisms. Tetanus, cardiac work loops, afterload and constant load contraction studies, calcium imaging, sarcomere spacing, NAD/NADH and FAD/FADH studies can all be performed on a single cell with the SI-H CTS200 Cell Tester system. According to Dr. Harm Knot (staff muscle physiologist), “The new Cell Tester, a novel cell biology research tool, is set to revolutionize the emerging field of
