The Welch 8890A, GEM 1.0 is a durable vacuum pump with a superior vapor handling capability. The Welch 8890A, Direct Drive Vacuum dual stage rotary vane mechanical vacuum pump offers an excellent ultimate pressure of 1 x 10-1 Torr. These pumps are commonly used for vacuum furnace evacuation, backing turbomolecular pumps, backing diffusion pumps, rotary evaporation, refrigeration system evacuation, epoxy degassing, vacuum sterilization, backing mass spectrometers, freeze drying, vacuum centrifugal applications, vacuum distillation, space research, and other vacuum processes. This pump also is well suited for use in gas analyzers, continuous gas-flow lasers, general-purpose drying, and similar uses where a middle-range vacuum level is required.
Multiple purpose capabilities allow you to measure a wide range of analytes.
To achieve the GloMax-20/20's high sensitivity, the luminescence channel is positioned directly below the sample well. These conditions maximize light capture. In addition, a low-noise photomultiplier tube ensures that collected light is not compromised. The dynamic range of the GloMax-20/20 is more than adequate to cover common luminescence applications, thus reducing the need to dilute samples.
The GS-800 calibrated densitometer offers superior accuracy, sensitivity, and data reproducibility. It automatically self-calibrates the optical density to optimize detection.Unlike laser densitometer systems, the GS-800 calibrated densitometer has both transmittance and true reflectance capabilities that allow accurate scans of both transparent and opaque samples. The advantage of true reflectance scanning is accurate detection and analysis of molecules on the surface of membranes, rather than molecules distributed throughout the membrane matrix.

Multiskan Spectrum makes getting results easier, replacing separate spectrophotometers and microplate reading instruments by providing both functions in one convenient, compact instrument. The Multiskan Spectrum is truly two instruments in one, combining both cuvette reading capabilities and advanced microplate reading in one convenient, compact instrument. You can easily take quick absorbance measurements in a cuvette between the cycles of a microplate enzyme kinetics experiment.
For maximum flexibility, Multiskan Spectrum accepts all microplate for mats from 6- to 384-wells, as well as cuvettes from standard to ultra micro capacities in glass, plastic, or quartz. You can take multiple photometric readings per well on large format plates, or single measure ments requiring just 30 μl in 384-well plates.
Scanning range of 200 – 1000 nm. The built-in monochromator makes it simple to select any wavelength from 200 nm to 1000 nm in 1 nm steps without ever changing a filter. Sample absorbances can be scanned over the whole spectrum either in microplates or cuvettes.
Typical applications of the Multiskan Spectrum
Thermo Scientific™ NanoDrop 8000 is a muti-sample micro-volume UV-Vis spectrophotometer. With the NanoDrop 8000, you can measure more samples in less time with the same reliability and patented sample retention technology of the NanoDrop 2000.

The NanoDrop 1000 Spectrophotometer measures 1 ul samples with high accuracy and reproducibility. The full spectrum (220nm-750nm) spectrophotometer utilizes a patented sample retention technology that employs surface tension alone to hold the sample in place. This eliminates the need for cumbersome cuvettes and other sample containment devices and allows for clean up in seconds. In addition, the NanoDrop 1000 Spectrophotometer has the capability to measure highly concentrated samples without dilution (50X higher concentration than the samples measured by a standard cuvette spectrophotometer).
UV/VIS spectrophotometry is simple for samples as small as 1 ul using the NanoDrop 1000 Spectrophotometer. The small sample requirement and ease of use make the NanoDrop 1000 Spectrophotometer ideally suited for measuring:
• Nucleic acid concentration and purity of nucleic acid samples up to 3700 ng/ul (dsDNA) without dilution
• Fluorescent dye labeling density of nucleic acid microarray samples
• Purified protein analysis (A280) up to 100 mg/ml (BSA)
• Expanded spectrum measurement and quantitation of fluorescent dye labeled proteins, conjugates, and metalloproteins
• Bradford Assay analysis of protein
• BCA Assay analysis of protein
• Lowry Assay analysis of protein
• Pierce Protein 660 nm Protein Assay
• Cell density measurements
• General UV-Vis spectrophotometry
