Let’s Dive into Thermo Fisher Scientific Finnpipette F2 20ul Fixed 4652130
The Thermo Fisher Scientific Finnpipette F2 20ul Fixed 4652130 is a precision instrument, a fixed-volume pipette designed for delivering exactly 20 microliters of liquid. Made by Thermo Fisher Scientific, a renowned name in scientific equipment, this pipette promises accuracy and reliability for laboratory professionals. This particular model stands out for its fixed volume, eliminating potential user error associated with adjustable pipettes.
My journey to the Thermo Fisher Scientific Finnpipette F2 20ul Fixed 4652130 began with a persistent need for consistent and precise liquid dispensing in my work. I needed a dependable instrument for preparing solutions and reagents, where even the slightest variation in volume could skew results. The existing adjustable pipettes in the lab were constantly being recalibrated, and the variability between users was a constant source of concern.
Unboxing the Thermo Fisher Scientific Finnpipette F2 20ul Fixed 4652130 was an underwhelming, yet reassuring experience. It’s a pipette; the packaging is functional, not flashy. The instrument felt solid, though surprisingly lightweight, in my hand; the materials seemed to be high-quality polymers, promising good chemical resistance.
Compared to variable-volume pipettes from Eppendorf and Rainin that I’ve used extensively, the Finnpipette F2 20ul Fixed initially seemed almost too simple. The others offer volume adjustments and more ergonomic grips. However, the promise of fixed-volume precision and fewer moving parts for failure ultimately swayed my decision.
My first impression was one of cautious optimism. Its simplicity could be its greatest strength. Only time and rigorous testing would reveal its true worth.
Real-World Testing: Putting Thermo Fisher Scientific Finnpipette F2 20ul Fixed 4652130 to the Test
First Use Experience
The initial testing of the Thermo Fisher Scientific Finnpipette F2 20ul Fixed 4652130 took place in a controlled laboratory environment. I was preparing serial dilutions for a sensitive assay, a task that demands extreme accuracy. The pipette was used with both aqueous solutions and solutions containing low concentrations of solvents.
The performance was noticeably consistent across different solution types. I did not observe any dripping or bubble formation that sometimes occurs with less precise pipettes. The action was smooth, and the plunger provided a clear tactile stop, ensuring complete dispensing of the 20ul volume.
Using the pipette was remarkably straightforward. The fixed volume eliminated any ambiguity in setting the desired volume, leading to quicker workflows. There were no surprises after the first use; the Finnpipette F2 20ul Fixed performed exactly as expected, delivering consistent volumes with minimal effort.
Extended Use & Reliability
After several weeks of consistent use, the Thermo Fisher Scientific Finnpipette F2 20ul Fixed 4652130 has held up exceptionally well. There have been no noticeable changes in performance or reliability. The action remains smooth, and the dispensed volumes remain consistently within acceptable tolerances, verified by gravimetric analysis.
The pipette has shown excellent durability. Despite daily use and exposure to various laboratory chemicals, the exterior shows no signs of degradation or discoloration. Cleaning is straightforward; a simple wipe-down with ethanol or isopropanol is sufficient to remove any contaminants.
Compared to my previous experience with adjustable pipettes, the Finnpipette F2 20ul Fixed is a clear winner in terms of reliability and consistency. While adjustable pipettes offer flexibility, they are also prone to calibration drift and user error. The Finnpipette‘s simplicity guarantees consistent and accurate dispensing.
