ElectrophoresisElectrophoresis equipment is used to separate mixtures of protein, DNA or RNA, based on their electric charge, size and other physical characteristics, by passing them through a medium such as a polyacrylamide gel, an agarose gel or a capillary tube. Electrophoresis equipment includes horizontal and vertical gel electrophoresis chambers, isoelectric focusing systems, 2D electrophoresis and capillary electrophoresis instruments. Precast gels with a gradient can be used or gels can be hand cast. Samples are run alongside ladders or markers to identify the approximate size of a molecule. Separated proteins and nucleic acids in the gel can be stained or probed with fluorescent markers and then imaged and detected using gel documentation instruments, transilluminators, densitometers and scanners. Find the best electrophoresis equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples. Find the best atomic absorption, photoelectron and optical emission spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Fluorescence SpectroscopyFluorometers and spectrofluorometers (also called fluorescence spectrometers) are used to measure the intensity and wavelength of fluorescent light emitted from a sample after excitation by illumination. Spectrofluorometers utilize monochromators to select the desired wavelengths, whereas filter fluorometers employ a set of filters. Spectrofluorometers for measuring steady-state fluorescence and lifetime fluorescence (or time-resolved fluorescence) are available, as well as fluorescence microscopes and microplate readers. Find the best fluorescence spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses. Find the best IR spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.

Biosensor instruments may be photometric, typically using surface plasma resonance (SPR), electrochemical or QCM (quartz crystal microbalance) biosensors. Biosensors should be selective, portable, robust and sensitive and have a fast response time. Systems may be manual or automated and usually have associated software.Cell Adhesion AssaysCell adhesion assays are used to quantitate attachment and analyze the molecular mechanisms for extracellular matrix adhesion, cell migration and sensitivity to inhibitors.

Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins.

A library is generated by synthesis with a chemical reactor system or by computer-based modeling of compound combinations. When undertaking combinatorial chemistry consider reagents, buffers, resins and standards.GlycobiologyGlycobiology encompasses research into the biological functions, synthesis and structures of glycans, including glycoproteins, glycolipids, proteoglycans and free oligosaccharides. Mass spectrometers and their software are commonly used in the study of glycobiology, along with structure predicting tools, chromatography and NMR.Balances and Moisture AnalyzersBalances & Moisture Analyzers / weighing scales measure static or dynamic loads.
