Analytical Lab Equipment Manufacturers

Analytical lab equipment manufacturers play a pivotal role in furthering scientific research. By offering reliable instruments for specific fields that support experiments and discoveries, these manufacturers provide essential support. Their products undergo stringent quality assurance testing procedures and adhere to industry standards.

Chemical laboratory equipment is designed to measure physical properties of liquids, gases and translucent solids. It's often found in laboratories for quality assurance or verifying raw material consistency before manufacturing begins.

Flow Injection Analyzer

Flow injection analysis (FIA) is an automated wet chemistry technique that combines continuous flow and sample injection. When applied, analytes are introduced into an analyte carrier stream which transports them towards a detector; analysis signals generated from such detectors typically depend on changes in absorbance, electrode potential or another physical parameter.

The FIA technique offers fast sampling rates. The system utilizes a transporting device called a manifold which consists of multiple channels that merge into one stream that heads towards the detector. Each channel contains reagents which react with sample and transport it onward to be detected by detector.

FIA systems provide an attractive alternative to traditional analytical methods by processing large volumes of analytes with little waste generation or volume required of sample or reagents. Not only does FIA reduce volume requirements and waste generation but it can also cut waste generated in laboratories.

Spectrophotometer

A spectrophotometer uses a controlled light source to generate desired wavelengths, before using lenses and collimators to break apart photons into individual wavelengths, then monochromators to separate these rainbow-like wavelengths into narrow bandwidths, wavelength selectors for transmitting only desired wavelengths, sample solution in cuvette exposed to this light, and detectors quantifies intensity of either transmitted or reflected signal.

Modern spectrophotometers feature multi-angle geometry that more closely mirrors how humans perceive color. This feature is particularly helpful for measuring special effect pigments and automotive coatings with mica or pearlescent additives, while it can also be used to test liquid ingredients for consistency, pharmaceutical products requiring specific colors, and end-of-line quality control of product color.

Automatic Density Meter

Density meters are instruments designed to accurately determine the density of liquid or semi-liquid materials. Operating on the oscillation principle, density meters use a U-shaped tube filled with sample material which vibrates at various frequencies as dictated by its density for accurate measurement.

Automatic digital density meters offer greater accuracy with faster results compared to manual hydrometers or pycnometers, which may be susceptible to human errors. This makes them ideal for production environments in which maintaining consistent quality control processes is crucial.

Rudolph Research Analytical offers four models of their automatic density meters which are ideal for research and production applications in multiple industries. With ease-of-use features like specific gravity measurement, Brix % alcohol content measurement, temperature compensated density concentration measurement as well as concentrated sulphuric acid concentration concentration monitoring these instruments provide accurate readings. They're even compliant with Good Manufacturing Practice regulations (cGMP), making them suitable for pharmaceutical and chemical laboratories alike.

Gas Chromatograph

Gas chromatography (GC) is a separation technique used to identify organic molecules. It combines liquid-solid and gas-liquid column chromatography, with mass spectrometry to obtain information about the chemical composition of samples. Typical GC instruments consist of an injection port, analytical column, carrier gas flow control equipment (such as ovens and heaters for maintaining temperature of both injection port and column), chart recorder, and detectors. 

GC systems typically utilize a column to separate sample components based on their boiling points. Each component elutes from the column at different times and its peak position on the chromatogram indicates when it reached its detector. Quadrex's Capillary GC Columns feature superior Polymide Outer Coating and Graphite Vespel Ferrules to meet laboratory needs and help maximize GC system capabilities. 

All columns undergo preconditioning and quality checks prior to shipping for use in laboratories worldwide, making Quadrex a trusted Analytical Lab Equipment Manufacturer.
