Gel Electrophoresis Units (Agarose, SDS-PAGE)

Gel electrophoresis units are essential laboratory systems used to separate biomolecules—primarily DNA, RNA, and proteins—based on their molecular size and charge. These units are critical in molecular biology, biochemistry, forensic science, genetic diagnostics, and protein characterization, forming the backbone of many routine and high-precision lab workflows. There are two main types of gel electrophoresis units: horizontal agarose gel systems, commonly used for nucleic acid analysis, and vertical polyacrylamide gel electrophoresis (PAGE) units, typically used for protein separation via SDS-PAGE. Agarose gel electrophoresis units are ideal for separating and visualizing DNA and RNA fragments. Applications include PCR product verification, restriction enzyme digestion analysis, plasmid mapping, and genotyping. These systems feature gel trays, combs, casting equipment, and buffer tanks, and often include UV-transmissive gel platforms for downstream imaging. SDS-PAGE units, or vertical gel systems, are designed for high-resolution separation of proteins by molecular weight under denaturing conditions. These are used in workflows such as Western blotting, protein purification analysis, molecular weight determination, and biomarker identification. Many systems accommodate precast or hand-cast gels and are compatible with a range of buffer compositions and gel percentages. Advanced gel units may include built-in cooling systems, leak-proof chambers, color-coded electrodes, and compatibility with high-throughput applications. Their modular design allows researchers to swap components easily and adapt to changing experimental needs. At Wasteless Bio, we offer high-quality, surplus gel electrophoresis units from leading brands. Listings include specifications such as gel dimensions, voltage compatibility, sample capacity, buffer volume, and cooling or comb options. Purchasing through Wasteless Bio allows labs to reduce procurement costs, minimize laboratory waste, and maintain access to trusted gel systems that deliver high performance and reproducibility across a wide range of molecular separation tasks.
