| 0 | Odyssey® CLx Imaging System | 2 | 1 | حبة | 2 | Laser/Microscope • Image Field Size 25 cm × 25 cm • Dynamic Range* Manual: 16 bit (>4 logs), Auto: 22 bit (>6 logs) • Laser Lifetime 40,000 hours typical • 700 Channel Laser Source Solid-state diode laser at 685 nm • 800 Channel Laser Source Solid-state diode laser at 785 nm • Detectors Silicon avalanche photodiodes • Scanning Speed 5-40 cm/s • Resolution 21-337 µm • Focusing Range Microscope is adjustable 0 mm-4 mm above the scan bed to obtain best signal-to-noise ratio. * This dynamic range is obtained in a single acquisition. Operation Specifications • Operating Conditions 15-35 °C and dew point no greater than 20 °C • Power Requirements Universal input range is between 100-240 VAC (voltage fluctuations not to exceed 10% of the nominal voltage); 4 Amp maximum; at 120V, 0.5 Amp typical when idle; 50/60 Hz. Software Specifications • Empiria Studio® Software Requires a minimum of 8 GB of RAM; 64-bit versions of Windows 7 or 10; Mac OS Sierra or High Sierra • Image Studio™ Software For operating system compatibility, see this table. • Please contact LI-COR for compatibility with other software packages. | 0 |
| 0 | Branson Ultrasonics™ CPX Series Ultrasonic Cleaning Bath | 3 | 1 | حبة | 3 | Outfit your lab with a classic tabletop cleaner, offering high-tech design, solid construction and featuring reliable digital controls with power tracking capabilities. Bransonic CPX ultrasonic bath cleaners feature digital controls with power tracking capabilities to adjust for light or heavy loads, high/low power control, degassing and sleep mode. • Sweep frequency eliminates standing waves and creates consistent cavitation throughout tank • 40kHz rugged industrial transducers • 99 min. digital timer with continuous ultrasonic operation • With built-in pour drain, tank cover • Plastic body, chemical-resistant Ultrasonic Power Tracking • Immediately brings tank's frequency back to its optimum point • Control circuitry actively tracks operating frequency of bath • Delivers unwavering cavitation, steady activity in bath even when load conditions change Degassing and Conditioning the Solution • Can be set up to 99 minutes • Extended degas time periods allow beyond cleaning applications such as sample preparation, which includes degassing liquids, mixing and homogenization, dissolving solids, cell lysing, and dispersion of particles High/Low Power Control • Allows user to lower amplitude of acoustic energy in bath: 100% power to tank for normal applications, 70% power for delicate applications • Helps to avoid damage to components in bath during ultrasonic process Sleep Mode • An energy-saving feature • When cycle is complete and no control keys are touched for 15 minutes, unit goes into sleep mode • Touching any key on controller causes unit to come back on • Controls are located above and behind cleaning tank in an easily accessible control tower panel, and raised above the tank to avoid damage from cleaning solutions | 0 |
| 0 | 3-channel flow cell | 4 | 1 | حبة | 4 | The IBI 3-channel Flow Cell (formerly Stovall 3-channel Flow Cell) is designed as a one-time use, affordable, sterile 3-channel flow cell apparatus for the creation of biofilms. This device allows for real-time, direct, non-destructive, on-line examination of biofilms with either a traditional transmission light microscope or a scanning confocal laser microscope which will produce a 3-D image of the biofilm. The 3-channel flow cell is gamma irradiated and comes complete with bubble trap (ACCFL0002) and peristaltic pump tubing and connective tubing. The 3-channel flow cell contains a #1 Glass cover slip. The underside of this cover slip is where the biofilm will attach and grow. When the experiment is complete, the cover slip is cut using a hand-held glass cutter (ACCFL0014) and removed along with the biofilm. Features and Benefits • The 3 separate channels allow for the simultaneous growth of 3 individual biofilms in the same cell. • Luer connectors in the effluent tubing (downstream from the cell) allow for collection of effluent for further analysis. • 3-channel full assembly measures 91 inches long including cell and tubing. • Included bubble trap captures air bubbles before they reach the cell and also smooth peristaltic pump pulsations. • System comes sterilized (gamma irradiated) and ready for use. • Culture media bottles and peristaltic pump purchased separately. | 0 |
