Counting Blood Cells with Dino-Lite Microscopes
Dino-Lite handheld models combined with a stand facilitate the laboratory capability to capture images and videos. Setup A provides precise XYZ movements when using a proper combination of coaxial lighting. Both the AM73515MT8A and BL-CDW back light offer dark field and bright field options which allow users to easily identify bacteria, protozoans, and distinguish between red and white blood cells. The AM73515MT8A also offers 5MP high resolution and a magnification range of 700x-950X. Using the full-screen 2X Digital Zoom feature found in the free imaging software at 950X mag with 5MP resolution, users can achieve 1900X magnification with 1.3MP resolution. Three setup combinations are recommended:
Innovative NIRaman Combi Fiber Probe
Art Photonics introduces a new combined fiber optic probe (NIRaman) enabling simultaneous real time measurements at the same point with Near-infrared spectroscopy (1000-2500nm) and Raman spectroscopy (785 – 1000nm) methods. The wavelength ranges of both channels are separated but both channels can work simultaneously. NIRaman Combi fiber probe, which not only significantly expands the capabilities of the well-known FlexiSpec® product line, but also opens up new opportunities for the development of various Combi-probes. Raman and NIR spectra contain qualitative and quantitative information on the chemical composition and physical properties of the substance.
Piezoelectric Micropumps and Their Biomedical Applications
Small, lightweight and powerful, the piezoelectric micropumps are perfect for portable, battery-operated medical devices and diagnostic applications. Meanwhile, excellent gas pumping capability renders the pump opportunities in the environmental and industrial hygiene applications. This micropump can be used to circulate media or continuously supply fresh media for cell culturing or tissue engineering with greatly reduced risk of contamination over time. The continuously adjustable flow rates are able to actively optimize the media conditions, and the virtually steady flow can minimize the perturbation to cells.
