Real-World Testing: Putting Axygen Tip Filter 20UL Eppen PK10 TF-400 to the Test

First Use Experience

I tested the Axygen Tip Filter 20UL Eppen PK10 TF-400 in my molecular biology lab, where I routinely perform PCR and qPCR assays. These assays are incredibly sensitive to contamination, making reliable filter tips an absolute necessity. The tips were used for dispensing DNA templates, primers, and enzymes.

I used the tips under standard lab conditions, with typical temperature and humidity levels. The lab is generally clean, but airborne particles are always a concern. The tips performed flawlessly, providing a tight seal with the Eppendorf pipette and accurately dispensing the required volumes. There were no noticeable leaks or inconsistencies.

The ease of use was excellent. The tips snapped securely onto the pipette, and the dispensing action was smooth and controlled. The filter didn’t impede the flow of liquid, and there was no noticeable drag or resistance. I did not need any additional time to get used to the Axygen Tip Filter 20UL Eppen PK10 TF-400.

There were no major issues after the first use, but I did notice that the filter sometimes retained a small amount of liquid. This required a slight adjustment to my pipetting technique to ensure complete dispensing.

Extended Use & Reliability

After several weeks of using the Axygen Tip Filter 20UL Eppen PK10 TF-400 for multiple PCR and qPCR experiments, the tips have consistently performed well. There has been a noticeable decrease in the number of contaminated samples, which has saved me time and resources. The results are more reliable.

The tips have proven to be durable, with no signs of physical degradation or filter compromise. They withstand repeated use and autoclaving without any noticeable change in performance. I have not experienced any issues with cracking or breakage.

Maintenance is straightforward. The tips are disposable, so there is no need for cleaning or sterilization after use. I only need to ensure proper storage in a clean, dry environment to prevent contamination before use. Contamination control is key in my lab.

Compared to my previous experiences with unfiltered tips, the Axygen Tip Filter 20UL Eppen PK10 TF-400 has significantly outperformed them in terms of contamination control and reliability. This has improved the quality of my research and increased my confidence in the results. The cost is higher, but the returns are worth it.
