Transilluminators are used to visualize nucleic acids or proteins within electrophoresis gels by illuminating the sample from beneath. Available in UV, blue light, or white light versions, these units enable safe and effective observation of gel bands for analysis, cutting, or transfer.

Low-profile, compact designs with adjustable intensity settings ensure minimal DNA damage during excision. Blue light models are especially suitable for labs concerned with UV exposure and sample degradation.

Transilluminators are foundational tools in any life science lab working with gel electrophoresis, offering both visibility and protection for sensitive biomolecules.
