Transferring cell lysates and cDNA preparations, I noticed significantly less residual material clinging to the inner walls compared to my usual tips. This was particularly evident when pipetting small volumes, where every microliter counts. The unique, round-ended design also seemed to facilitate smoother aspiration and dispensing, reducing the risk of aerosol formation.
One unexpected quirk, though minor, was their slightly different feel during ejection; they released from the pipette with a softer click, which is a testament to their flexible construction but took a moment to get used to. No significant issues arose, but this slight tactile difference was noticeable.
Extended Use & Reliability
Over several weeks of intensive use, the Sorenson MltiFlex Pipet Tips, Sorenson BioScience 13790 Round-Ended Tips, Pack of 200 consistently performed. They held up exceptionally well to repeated cycles of aspiration and dispensing, even with aggressive pipetting techniques sometimes necessitated by tight protocols. I deliberately subjected them to a range of temperatures, from chilled buffer solutions to slightly warmer incubation steps, and observed no signs of degradation or increased brittleness.
Durability was impressive; I accidentally dropped a rack of these tips on the concrete floor of my workshop storage area, and to my surprise, very few tips were damaged or deformed, unlike many standard tips which would have shattered. Their ability to withstand a degree of mishandling without chipping or deforming is a significant advantage for busy labs. Cleaning or sterilization wasn’t directly applicable as they are single-use, but their autoclavable nature, as stated, provides an added layer of confidence for sterile applications.
Compared to budget brands, these tips offer a clear advantage in sample recovery and consistency, justifying their higher price point. They felt more robust and performed more reliably than even some mid-range tips I’ve used previously.
