Laboratory gel dryers are specialised devices used to dry polyacrylamide and agarose gels after electrophoresis for long-term preservation and documentation. These dryers work by applying heat and vacuum pressure to gently remove moisture from the gel without causing distortion or damage to the bands. Gel drying is a critical step in molecular biology and biochemistry, where researchers need to preserve gels for further analysis, storage, or presentation. Many gel dryers feature adjustable temperature settings and vacuum levels to accommodate different gel types and thicknesses. By providing a reliable method to preserve gels in their final state, laboratory gel dryers ensure that experimental data can be accurately archived and referenced in future studies.
