Bran Luebbe InfraProver II NIR SpectrometerImage Coming Soon

Bran Luebbe InfraProver II NIR Spectrometer

Cambridge ID #: 13370

Description: The DO308 drying oven is ideal for accurate water determination of solid or viscous samples like:

  • Substances that release water only at elevated temperatures such as plastics in powder or granular form
  • Substances that cause side reactions with Karl Fischer reagent such as oxidizing inorganic salts
  • Substances that cause problems in the titration vessel due to their consistency such as fibrous or pasty substances
  • Substances that are poorly soluble or insoluble such as wool, dough, tar or coal

Specifications:

  • Temperature range: 40 - 300 °C
  • Temperature accuracy: ±5 °C (@300°C)
  • Footprint housing: 256 x 180 mm
  • Dimensions overall: 500 x 220 mm
  • Voltage (auto selection): 100 ... 230 VAC   
  • Max. power consumption: 450 W
  • Height: 390 mm
  • Weight: 9.1 kg

Features and Benefits

  • Easy and fast manual handling - Easy handling for left and right handed operators. Sample exchange and sample transport into the heated zone of the oven is provided for by the simple transport system with a magnetic guide rod attached to the glass sample boat.
  • Equilibrium conditions are quickly reached - The cold and the hot zone can be purged separately with dry carrier gas using a stopcock. Ambient moisture introduced during sample exchange or addition via the sleeve opening is quickly carried away. Therefore, a stable drift is reached within a short period of time.
  • Enhanced operational safety - There is no need to remove the transfer tube from the titration cell after switching off the oven; just open the stopcock to avoid contamination of the oven due to underpressure. Different temperature ranges can be pre-programmed in one cycle. Safety is further improved by automatic shut down after the analysis is completed.
  • Ready for use - All necessary parts including the drying unit with gas flow measurement are part of the standard delivery. If purging with dry air is desired, an optional air pump is available.

Photometrics CoolSNAP HQ Microscope Monochrome Camera

Photometrics CoolSNAP HQ Microscope Monochrome Camera

Cambridge ID #: 14743

Includes Computer loaded w/ software

The Photometrics CoolSNAP HQ Monochrome camera is a fast, high-resolution digital camera system designed for low-light scientific and industrial applications. This cooled CCD camera system provides 12-bit digitization at both 10 MHz and 20 MHz. The fine pitch of the pixels, 6.45 x 6.45 microns, is ideally matched to the resolution of optical microscopes. Megapixel resolution and small pixels allow imagingof very fine detail, yet the pixels can be easily binned to improve sensitivity. New interline CCD technology provides high quantum efficiency, most notably in the near-infrared (NIR) portion of the spectrum.

Specifications:

  • CCD image sensor: Sony ICX285; progressive-scan CCD
  • CCD format
    • 1392 x 1040 imaging pixels;
    • 45 x 6.45-μm pixels;
    • 77 x 6.6-mm imaging area (optically centered)
  • Linear full well
    • 15,000 e- (single pixel);
    • 30,000 e-(2x2 binned pixel)
  • Read noise
    • 6 e- rms @ 10 MHz
    • 8 e- rms @ 20 MHz
  • Nonlinearity: <1%
  • Readout bits/speed: 12 bits @ 20 MHz or 10 MHz; software selectable
  • Frame readout: 100 ms/frame
  • CCD temperature: -30 ÌŠC regulated
  • Video output: RS170/PAL selectable
  • Dark current: 0.05 e-/p/s (-30 ÌŠC)
  • Operating environment: 0 to 30 ÌŠC ambient, 0 to 80% relative humidity noncondensing
