Data AnalysisData analysis hardware and software is available to make data processing straight-forward yet powerful. Data software can be used for math and stats, technical graphing and image analysis. In addition, software is available for specific data analysis of electrophoresis, densitometry, ELISA and DNA sequencing.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.

Cheminformatics focuses on compound information, whereas bioinformatics is mainly applied to analysis and modeling of genomics, genetic and sequencing information. Hardware and software is available for data acquisition, analysis, management and storage.Sample ManagementSample management systems include sample storage devices such as freezers and plate storers, sample environment enclosures and sample organization, retrieval and sorter systems. Useful system features include high-throughput, automation, robotic arms, automated liquid handling and associated database systems. Accessories in sample management include barcode scanners, heat sealers and tubes.Robotic InstrumentsRobotic instruments can be used for high-throughput automation of many lab processes. Such processes use instruments for assays like cell based assays and ELISA, for sample preparation like shakers, centrifuges and incubators, and for analysis such as sequencing and western blot analyzers. Useful features of robotic instruments include speed, reproducibility, barcode readers, software and automation.Software PlatformsSoftware platforms are useful for various stages of laboratory experiments from data collection to data storage and processing. For instance lab software is available for system control, data management, data analysis and qualification / validation.Fumehoods and Biological Safety CabinetsFume hoods and biological safety cabinets are used to provide personnel, sample and environmental protection by limiting exposure to hazardous materials either by venting or enclosing hazardous sample space. Fume hoods include filtered and ductless fume hoods, general ducted fume hoods, laminar flow cabinets and cabinets for powder weighing. There are three classes of biological safety cabinet, dependent on the level of protection provided. Class I provide personnel and environmental protection, class II provide product, personnel and environmental protection. Class III provide the highest level of protection and are designed for use with high-risk biological agents. Other ventilated workspaces for the laboratory include glove boxes, glove bags, anaerobic and hypoxic workstations.
