Real-World Testing: Putting Sorenson MltiGuard Barrier Pipet Tips, Sterile, Sorenson BioScience 14200 M ultiGuard Tips, 7.3 Cm (23/4″) Length, Pack of 1000 to the Test
First Use Experience
I initially tested the Sorenson MltiGuard Barrier Pipet Tips in our level-3 biohazard lab, specifically during PCR amplification of potentially infectious viral samples. The procedures involved minute volumes of highly sensitive material, demanding the highest level of precision and contamination control. The sterile nature of the tips was paramount in this context.
Working within a biosafety cabinet, the ergonomic design of the tips allowed for easy attachment to the pipettor, even while wearing heavy-duty gloves. The liquid handling was smooth and precise, and there was a noticeable decrease in observable aerosol formation during dispensing, compared to standard tips. The 7.3 cm (2 3/4″) length was perfect for reaching the bottom of various tubes and vials without contaminating the pipettor.
The initial use was remarkably straightforward, with no noticeable issues regarding pipettor fit or liquid retention. The tight seal between the tip and the pipettor nozzle reassured me of the reduced risk of leakage and aerosol formation. I felt more confident in the integrity of the experiment using the Sorenson MltiGuard Barrier Pipet Tips than with previous, cheaper options.
Extended Use & Reliability
After several weeks of using the Sorenson MltiGuard Barrier Pipet Tips in various sensitive assays, their reliability proved to be outstanding. We performed hundreds of PCR reactions and radioisotope labeling experiments, and consistently observed minimal background contamination. The barrier within the tip was effectively preventing aerosols from contaminating the pipettor and subsequent samples.
Despite rigorous daily use, the tips showed no signs of degradation or malfunction. The consistent performance, even after autoclaving the CellRacks (when empty) for reuse, highlighted the durable construction of the product. I became increasingly confident in the quality of data generated using the Sorenson MltiGuard Barrier Pipet Tips.
Maintenance was minimal, primarily consisting of proper disposal of used tips in designated biohazard containers. The consistency of these tips outperformed our previous experiences with cheaper alternatives, where we frequently encountered issues with inconsistent volumes or leaking tips. The peace of mind knowing that each tip would perform as expected was worth the extra cost.
