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 waterbath with the most modern comfort and highest safety The
Memmert waterbath is available in six sizes and two performance classes. In addition to the Basic class for simple temperature control tasks, the Excellent version offers precise test procedures with maximum safety: electronic overtemperature protection and a multitude of visual and acoustic signals, e.g. when the filling level is too low, overtemperature, but also for input acknowledgement or at the end of the programme. In the largest water bath model, an optional circulation pump ensures even better thermal homogeneity of the water.

The 24″ tall, 7 1/4″ diameter tank comes filled with 13 lbs. of our exclusive ion-exchange resins that remove minerals from the water through a process that binds them to the resin. Because the majority of the impurities are dissolved, deionization produces highly purified water, so no more spots! The two valves control the water flow through the filter. This allows you to bypass the filter when it is not needed to prolong the life of the resin. Add our Stainless Steel Quick Disconnect Set for faster, easy use. The life of the resin depends upon the amount of total dissolved solids (TDS) in your water. Want to know your TDS level? Check out our easy-to-use TDS Meter. The replacement resin is safe, disposable, and easy to install.
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.
