Performance & Functionality

The Molecular Bio-Products ART Gel Self-Sealing Barrier Tips, Molecular BioProducts 2155, Pack of 960 excel in their primary function: preventing contamination. When pipetting sensitive samples like RNA or DNA, the barrier actively prevents aerosols from being drawn into the pipettor shaft. I have observed that during aspiration, the gel barrier effectively stops any fine mist from reaching the pipettor’s internal components. Likewise, when dispensing, especially with viscous solutions or when accidental over-pipetting occurs, the barrier acts as a failsafe, preventing liquid from backing up into the pipettor.

A key strength is their suitability for loading gels. The tip geometry and volume capacity (up to 100µL) make them perfect for delivering precise volumes into gel wells without disturbing the gel structure. The self-sealing nature means that even if the tip is partially submerged or encounters a bubble, the barrier is designed to prevent liquid from entering the pipettor’s piston mechanism. This significantly reduces the risk of cross-contamination between samples loaded into different wells and protects the pipettor from corrosive buffer components.

The primary weakness, if one could call it that, is their specialization. While their design for gel loading is a strength, for extremely high-volume or very low-volume applications outside of gel work, other specialized tips might offer marginal advantages. However, for their intended purpose, they perform exceptionally well, often exceeding the protection offered by standard filtered tips by providing a more robust, active barrier.
