Real-World Testing: Putting Molecular Bio-Products Tips for Rainin LiteTouch Pipettors, Molecular BioProducts 2769 Art Barrier, Sterile, Pack of 960 to the Test
First Use Experience
My initial tests with the Molecular Bio-Products 2769 Art Barrier tips were conducted in a standard molecular biology lab setting. I specifically focused on pipetting reagents known for their low viscosity, such as diluted acetonitrile solutions, which are notorious for their tendency to “boil shock” and create unpredictable volume readings. I also tested them with hazardous cytotoxic compounds, where the integrity of the barrier and tip is non-negotiable.
The performance in these conditions was, frankly, impressive. The tips consistently drew and dispensed accurate volumes, with significantly reduced signs of bubble formation or liquid clinging to the inside of the tip. This was particularly evident when working with samples close to the lower end of the 1-200 µL volume range.
Ease of use was immediately apparent. The Molecular Bio-Products 2769 Art Barrier tips attached securely to my Rainin LiteTouch pipettors without excessive force, and detachment was equally straightforward. There was no discernible learning curve; they simply performed as expected from the very first aspiration.
One pleasant surprise after initial use was the noticeable reduction in the need for repeated aspirating and dispensing to achieve an accurate volume. This translated into faster pipetting cycles and, more importantly, a greater sense of confidence in the precision of each transfer.
Extended Use & Reliability
After weeks of daily use, encompassing hundreds of pipetting cycles across various experiments, the Molecular Bio-Products 2769 Art Barrier tips have held up remarkably well. I haven’t observed any significant degradation in their performance or physical integrity. They continue to provide consistent and accurate results, even with extended use.
The durability of these tips is a standout feature. The flexible walls, a key design element, have proven resilient. I’ve used them to reach into narrow-necked tubes and sample from shallow wells without any hint of collapse, a common failure point with lesser-quality tips. There are no visible signs of wear and tear, such as cracking or deformities, even after repeated autoclaving (though these are sterile out of the box, sometimes re-sterilization is necessary in specific lab protocols).
Compared to my previous experiences with other brands, the Molecular Bio-Products 2769 Art Barrier tips consistently outperform. The reduction in aerosol generation and the reliable seal are distinct advantages that contribute to overall experimental success and a safer working environment. They have reliably eliminated the issues of sample carryover I sometimes encountered with less advanced tip designs.

Performance & Functionality
The primary function of these tips is to facilitate accurate and safe liquid handling. The Molecular Bio-Products 2769 Art Barrier tips excel in this regard. Their performance with low-viscosity solutions is exceptional, significantly reducing the impact of “acetonitrile-boil shock,” a phenomenon that can lead to inaccurate volume aspiration and dispense.
A key strength is the Art Barrier itself, which acts as a physical impediment, preventing hazardous or cytotoxic solutions from reaching the pipettor. This greatly enhances user safety and protects the expensive pipettor mechanism from contamination. The flexible walls and internal sealing rings are another significant strength, ensuring the tips maintain their shape and seal even when used in challenging situations, like sampling from gels or viscous solutions.
While they perform admirably across their specified volume range, the real magic happens when dealing with the lower end of that spectrum (1-50 µL) or with those notoriously difficult low-viscosity liquids. The ability to visually inspect the liquid level without directly touching the tip, thanks to the increased outside diameter, is a subtle but highly valuable feature that aids in precision. The increased surface area also allows for better visualization of discrete droplets, helping to prevent cross-contamination.
