MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments. Find the best microbiology products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Bioprocessing / FermentationBioprocessing is the use of biological materials to perform commercial, scientific or medical research processes. Biological materials used include cells, enzymes and organisms. Usually bioprocessing requires a batch or continuous bioreactor such as a fermentor or cell culture system. The advantages of using a reactor include high productivity, easy configuration, adjustable values and automation.YeastAutomationAutomation in laboratories and manufacturing processes enhances efficiency, precision, and scalability by reducing the need for manual intervention. It plays a critical role in improving productivity, minimizing human error, and accelerating workflows in fields like diagnostics, drug development, and industrial testing. Automation technologies include robotic systems, automated liquid handlers, and process control systems that streamline complex tasks and ensure consistent, reproducible results. Explore our peer-reviewed product directory to discover the best automation solutions, compare options, read user reviews, and get prices directly from manufacturers.MetabolomicsMetabolomics is the study of small metabolites (the intermediates and products of metabolism). It involves the identification and quantification of cellular metabolites using analytical technologies such as GC, HPLC, NMR, and LC/MS.BiofuelSample ProcessingSample processing is required to prepare samples prior to analysis. Technologies used for sample processing include homogenizers, grinders, mills and mixers.
