The “MltiFit Universal Fit” designation is a key specification, suggesting compatibility with a wide array of popular pipette brands. This feature aims to eliminate the need for specialized tips for different instruments, simplifying inventory and reducing potential errors. The natural color of the tips also contributes to their usability, as it does not interfere with the visual observation of samples.
Performance & Functionality
The primary function of any pipet tip is to accurately and reproducibly transfer liquids. In this regard, the Sorenson MltiFit Universal Fit Pipet Tips perform admirably. The 1-200 µl volume capacity is handled with a high degree of accuracy, provided the pipette itself is calibrated and used correctly. I experienced minimal carryover and excellent precision across multiple aspirate and dispense cycles.
A significant strength is the secure, leak-free seal they create with a variety of pipettes. This is crucial for preventing sample loss and ensuring the correct volume is dispensed. The wide mouth design, as stated in the product description, does indeed aid in the uptake of more viscous liquids, reducing the likelihood of air bubbles forming during aspiration.
However, one area where absolute precision can be nuanced is with extremely low volumes, below 5 µl, especially with very dilute aqueous solutions. While the tips themselves are well-manufactured, achieving perfect accuracy at these minute volumes also heavily relies on the pipette and user technique. For the intended 1-200 µl range, their performance is exceptional.
