UV-spectrophotometer double beam

The Neon® Transfection System enables fast and efficient delivery of nucleic acids into all mammalian cell types, including primary, stem, and difficult-to-transfect cells. The flexible and open system allows the user to perform high-quality transfections using optimized or user-defined protocols in three simple steps with as few as 2 × 104 cells per reaction. A novel reaction chamber provides a dramatic increase in transfection efficiency and cell viability. The Neon® Transfection System is:

• Efficient—up to 90% in many cell types, including difficult-to-transfect cells, primary, and stem cells
• Flexible—easily transfect from 2 × 104 cells to 6 × 106 cells per reaction
• Simple—easy to use, with a single reagent kit for all cell types
• Versatile—open system allows electroporation parameters to be optimized freely

The Clinical Lite professional stethoscope is a classic dual head stethoscope that is extremely light weight and affordable. The anodized aluminum dual head has a fiberglass diaphragm to optimally detect S1 and S2 heart sounds as well as Korotkoff sounds, while the bell side is optimally designed for assessing S3 and S4 heart sounds. The Clinical Lite professional stethoscope incorporates a snap-on diaphragm retaining ring and a non-chill bell ring providing the ease of use and maintenance, while enhancing patient comfort.
