Deliver precise vacuum and offer widely diverse control functions for a huge range of applications i (more)n the laboratory. The intuitive user guidance on the hand terminal ensures ease of operation; the process parameters can be entered over a touchscreen and a rotation knob. Ajustment capabilities: Units of measurement The operating language The operating mode Parameters, such as the setpoint pressure or suction capacity of the system direct over rotation knob. Depending on the selected operating mode, the graphic display of the hand terminal then indicates the respective process variables. The user can intervene in the ongoing process at any time with the hand terminal and its integrated touchscreen and rotating knob. The hand terminal can be located via vacuum pump system (paging); the hand terminal will answer with a signal tone. Four operating modes: Evacuate – The vacuum pump system evacuates a vacuum chamber with adjustable pump capacity. Pressure control – The vacuum pump system controls the system pressure to the set value (constant pressure). Automatic – The vacuum pump system automatically finds the vapour pressure of the sample and adjusts the process pressure accordingly. Individual pressure function – The vacuum pump system controls the process according to a user-defined pressure curve. The setpoint pressure and the opening and closing of the coolant valve (accessory) on the high-performance condenser can be easily entered for a range of set times. A repeat function allows successive repetitions of the programmed pressure curve.At any time during an active process, you can switch to manual process control. Functions for Evacuate and Pressure control will be available simultaneously.

The Invitrogen Tali Image-Based Cytometer is a 3-channel (bright field, green fluorescence, red fluo (more)rescence) imaging platform that performs suspension cell–based assays right from the benchtop. With the Tali cytometer, three-parameter population analysis can be completed in approximately 1 minute per sample using 25 μL sample volumes. In addition to the bright field channel, the Tali Image-Based Cytometer features two fluorescent channels (green and red), enabling it to simultaneously count green or red fluorescent stains, as well as cells expressing GFP and RFP. The Tali also offers an intuitive user interface, provides the option to save data and generate a report, which can then be transferred to a PC using the USB drive. Other features include presenting comprehensive data with graphic reports and allowing the export of data as .csv (comma separated value), .jpg, .fcs, and .pdf files for archiving and sample comparisons. Processing time: 10 seconds to 2 minutes, depending on the number of fields captured Sample concentration range: 1 x 105 – 1 x 107 cells/mL Particle/cell diameter range: 5 – 60 µm Required sample volume: 25 µL Optics: 3 channels (bright field, green fluorescence, red fluorescence) Excitation: Green channel LED (458 ± 20 nm), Red channel LED (530 ± 20 nm) Green channel filter: 466/40 EX, 495 LP Di, 525/50 EM Red channel filter: 543/22 EX, 580 LP Di, 585 LP EM Camera: 1.3 Mega pixels, 4x objective, 4x or 16x digital zoom Dimensions (WxDxH): 290 x 450 x 290 mm Weight: 9 kg
