Common Instruments for Molecular Biology Experiments

　　Molecular biology experiments include methods for preparing and analyzing macromolecules; extracting and separating proteins and nucleic acids; PCR; molecular hybridization and blotting; molecular cloning; foreign-gene transfer; protein expression; molecular markers and modification; sequencing and artificial synthesis; genomics; proteomics; biochips; bioinformatics; and RNA research.

　　What Instruments Are Commonly Used in Molecular Biology Laboratories?

　　Magnetic Stirrers

　　Magnetic Stirrers These instruments stir, or heat and stir simultaneously, low-viscosity liquids and solid-liquid mixtures. Using magnetic fields and vortex flow, a field generated by the base rotates a stir bar placed in the sample vessel. We recommend Meiyingpu stirrers. Meiyingpu specializes in manufacturing and selling stirrers and, after more than 30 years of development, offers models for experimental requirements across many industries.

　　Electronic analytical balances provide automatic fault detection, external calibration weights, automatic calibration, full-range four-point linear calibration, overload protection and other functions.

　　UV spectrophotometers use absorption spectra to investigate composition, structure and interactions between substances. They select wavelengths within the ultraviolet-visible region. Absorption occurs when molecules and atoms absorb specific wavelengths of incident light, producing transitions in molecular vibrational and electronic energy levels.

　　UV transilluminators, full-temperature-range shakers,temperature-controlled incubators, automatic steam autoclaves, refrigerators and ultralow-temperature freezers, pH meters and pH test strips.
