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.
Temperature range up to +95 °C (with cooling device CDP115 from +10 °C)
6 model sizes (7 to 45 litres interior volume)
various accessories: e.g. Peltier cooling device, flat and slanted lid, shaking device, floor grid, test tube rack
ultra-modern control technology
Water level maintenance optional
high-quality, rust-resistant and easy-to-clean stainless steel for interior and exterior housing
The Agilent 6460 Triple Quadrupole LC/MS delivers superior sensitivity for trace level analysis with performance specifications in
Signal-to-Noise ratio (S/N) and Instrument Detection Limit (IDL). IDL is a rigorous, statistically based metric that indicates practical
sensitivity performance of your quantitative assays. The Agilent 6460 Triple Quadrupole LC/MS achieves sensitivity and resolution
specifications with autotune.
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
Gentian violet slightly stains the nuclei of the leucocytes. The blood specimen is diluted 1:20 in a WBC pipette with the diluting fluid and the cells are counted under low power of the microscope by using a counting chamber. The number of cells in undiluted blood is reported per cumm (µl) of whole blood.
Haemometers are used for the determination of blood’s content of haemoglobin. The Marienfeld Superior haemometer according to Sahli is supplied as complete set consisting of:
