Protein Solution Concentration

The miVac sample concentrator provides an efficient and cost-effective alternative to traditional membrane centrifugation techniques for the concentration of protein solutions prior to separation through size-exclusion chromatography or electrophoresis or to analysis with X-ray crystallography. The membrane centrifugation process often results in loss of valuable sample because of protein binding to the membrane. The miVac sample concentrator ensures complete sample recovery even when taking proteins to very high concentrations. The miVac also offers the benefit of reduced spending on consumables. The instrument provides high performance, precise temperature control, and ease of use within a small benchtop footprint.

Time-of-Flight Spectrometer

The BenchTOF-dx mass spectrometer is a compact reflectron time-of-flight (TOF) instrument designed to generate classical electron impact ionization spectra for gas chromatography (GC) and comprehensive GC applications. The BenchTOF-dx enhances the benefits of standard TOF spectrometers for better handling of challenging compounds. The instrument's capability to generate classical spectra enables laboratories with proprietary spectral libraries to harness the performance of TOF mass spectrometry while maintaining the use of their current library system. The instrument incorporates groundbreaking new ion optics and electronics to deliver full spectral information with sensitivity normally associated only with the best quadrupoles running in selected ion monitoring mode.

Human Cytokine Array

The Quantibody Human Cytokine Array 4000 can detect quantitatively the expression of 200 different proteins in a single experiment. The kit consists of five quantitative, multiplex enzyme-linked immunosorbent assay-based slides: The Quantibody Human Inflammation Array 3 detects 40 inflammation markers. The Quantibody Human Chemokine Array 1 detects 40 chemokines. The Quantibody Human Growth Factor Array 1 detects 40 growth factors. The Quantibody Human Receptor Array 1 detects 40 soluble cytokine receptors. The Quantibody Human Cytokine Array 4 detects 40 cytokines and related proteins. These glass-slide antibody arrays feature standard concentration curves run alongside unknown samples to give quantitative results with picogram-per-milliliter sensitivity.

Single Quadrupole GC/MS

The Thermo Scientific ISQ single quadrupole gas chromatography/mass spectrometry (GC/MS) system features a unique, nonventing, full-source removal capability. Featuring the new ExtractaBrite ion source, the ISQ system offers simplified operation and maximum uptime for uninterrupted productivity across routine GC/MS applications, including forensics, toxicology, food safety, and environmental. This robust and rugged system provides high throughput sample analyses and 24/7 operation. The ExtractaBrite removable ion source is designed to provide maximum uptime and productivity by extending the length of time between required source maintenance. For today's fast-paced gas chromatography methods, advanced electronics allow the ISQ to acquire and write data to disc at accelerated rates for high-speed data acquisition in real-world applications.

Peptide Synthesizer

The Syro Wave is a microwave and parallel peptide synthesizer that combines the proven performance of the established MultiSynTech robotic synthesizer with Biotage microwave technology. It is the only system on the market to offer both microwave and parallel peptide synthesis capabilities. Prior to this combination, peptide synthesis labs have had to invest in both standalone parallel systems for productivity and cost efficiency, and standalone microwave systems for difficult or longer peptides. The new system increases productivity, yield, and purity while cutting costs and saving time.
