Real-World Testing: Putting Thermo Fisher Scientific Finntip Pipet Tips, Thermo Fisher Scientific Scientific 9401420 Finntip 1000 Extended, 100-1000 uL, Case of 5 to the Test
First Use Experience
My initial testing of these Finntips took place on my primary lab bench, a space accustomed to rigorous use and occasional chemical splashes. I loaded them onto my Finnpipette F1 pipettor, a combination I hoped would yield seamless operation. The Thermo Scientific Scientific 9401420 Finntip 1000 Extended tips snapped on with a satisfying, secure click, immediately indicating a good fit. I ran through a series of routine liquid handling tasks, pipetting everything from ultrapure water to more viscous solutions common in molecular biology protocols. The extended length proved its worth in those crucial moments of aspiration and dispensing, preventing accidental contact with the liquid surface when drawing from deeper vessels. This meant fewer wasted tips and a reduced risk of contamination.
Even after several hours of continuous use on the first day, the performance remained consistent. There was no noticeable drop in accuracy or any issues with liquid clinging to the inside of the tips. The polypropylene material felt robust, and I encountered no instances of the tips cracking or deforming under pressure, which had been a minor annoyance with lesser brands. The case, with its individual racks, made it easy to grab a single rack without disrupting the others, contributing to an efficient workflow.
Extended Use & Reliability
Over the subsequent weeks, these 1000 µL extended tips became my daily drivers. I used them for everything from setting up PCR reactions to preparing buffers and dilutions for various assays. Their reliability became a quiet cornerstone of my work; I could reach for them without a second thought, knowing they would perform as expected. The durability was impressive; even after repeated cycles of autoclaving (though these are non-sterile, they tolerate it well for general lab use), the tips maintained their integrity and fit.
I deliberately subjected a few tips to more challenging conditions, including extended immersion in solvents and repeated aspiration of particulate-laden suspensions. They held up admirably, showing no signs of degradation or compromise in their sealing ability with the pipettor. Compared to other brands I’ve used, these Finntips demonstrated superior clarity, allowing for better visual assessment of liquid levels and bubble formation. The overall cost-effectiveness of the case of five racks also became apparent; while the initial outlay is higher than bulk generic options, the reduction in errors and wasted reagents ultimately made them a more economical choice for critical work.
Breaking Down the Features of Thermo Fisher Scientific Finntip Pipet Tips, Thermo Fisher Scientific Scientific 9401420 Finntip 1000 Extended, 100-1000 uL, Case of 5
Specifications
The Thermo Fisher Scientific Finntip Pipet Tips, Thermo Fisher Scientific Scientific 9401420 Finntip 1000 Extended, 100-1000 uL, Case of 5 comes packaged as a case containing five racks, with each rack holding 96 tips. This totals 480 tips per case, offering a substantial supply for frequent users. The capacity range is clearly marked from 100-1000 µL, ensuring accuracy for a broad spectrum of liquid handling volumes within this common range. These tips are constructed from high-quality polypropylene, a material renowned for its chemical resistance and inertness, making it suitable for a wide array of laboratory reagents.
The key feature, their extended length, is designed to provide greater reach into tall vessels like reagent bottles or graduated cylinders, minimizing the risk of contaminating the pipettor shaft or the sample itself. This design consideration is critical for maintaining sample integrity and preventing cross-contamination, especially in sensitive experimental setups. While specified as nonsterile, they are autoclavable, offering flexibility for applications where sterilization is required post-pipetting, though for critical sterile work, pre-sterilized options would be necessary. The Thermo Scientific No. for this specific product is 9401420, a crucial identifier for reordering.
Performance & Functionality
In terms of core functionality, these Finntip 1000 Extended tips excel at delivering accurate and reproducible volumes within their stated range. The tight tolerance between the tip and the pipettor ensures a secure seal, preventing air leaks that could lead to inaccurate aspiration or dispensing. The polypropylene construction contributes to low liquid retention, meaning most of the aspirated volume is delivered, minimizing reagent waste and improving experimental accuracy. The extended shaft design is not merely a cosmetic addition; it significantly enhances usability by allowing access to the bottom of deeper labware, a common challenge with standard-length tips.
One of the standout aspects is the consistent performance across all tips in the case. I observed minimal variation in volume delivery from one tip to another, a testament to rigorous manufacturing standards. This reliability is paramount in research, where even small discrepancies can affect experimental outcomes. Compared to some budget brands where tip geometry can vary slightly, leading to less precise dispensing, these Thermo Fisher Scientific tips offer a noticeable improvement in overall consistency. Their performance meets and often exceeds expectations for standard laboratory applications.
Design & Ergonomics
The design of these Finntip 1000 Extended tips focuses on practical laboratory needs. The extended length is the most prominent ergonomic feature, granting users greater maneuverability and reach. This reduces the need to tilt or reposition larger containers, thereby streamlining the pipetting process and minimizing the risk of spills. The tips feature a smooth, polished internal surface which aids in complete liquid discharge and prevents residual liquid from adhering to the walls.
The connection point to the pipettor is precisely engineered to ensure a snug, airtight fit with most common pipettor brands, though they are specifically designed for Finnpipette models. This secure fit prevents slippage during aspiration or dispensing, a common frustration that can lead to inaccurate volumes and contamination. The polypropylene material also provides a comfortable, yet firm, grip when ejecting tips, even when wearing gloves. The clear, translucent color of the tips allows for good visibility of liquid meniscus and any air bubbles, which is crucial for accurate volume assessment.
Durability & Maintenance
The polypropylene material used in these Finntip 1000 Extended tips imbues them with good overall durability for their intended purpose. While they are single-use consumables, they are robust enough to withstand repeated pipetting cycles, autoclaving for sterilization (if needed), and moderate exposure to laboratory chemicals without cracking or becoming brittle. The construction is solid, and I did not observe any signs of premature wear or degradation during my testing period.
Maintenance for disposable pipet tips is inherently minimal; their primary function is to be used and discarded. However, their ability to be autoclaved provides a valuable option for protocols requiring sterile conditions after initial dispensing. Storage within the provided racks, which can be resealed, helps protect them from dust and contamination prior to use. Proper storage in a clean, dry environment will ensure their integrity until needed, maximizing the utility of the case.
Accessories and Customization Options
These Thermo Fisher Scientific Finntip Pipet Tips, Thermo Fisher Scientific Scientific 9401420 Finntip 1000 Extended, 100-1000 uL, Case of 5 are primarily consumables, meaning they are designed for single use rather than extensive customization. The main ‘accessory’ is the rack itself, which is designed for easy dispensing and can be resealed to protect the remaining tips. The tips are engineered to fit most standard pipettor brands, offering a degree of compatibility, although they are optimized for Finnpipette instruments.
The extended length itself is the primary design customization over standard tips. For users requiring sterile tips, Thermo Fisher Scientific offers pre-sterilized versions of their Finntips, which would be a complementary purchase if sterile applications are paramount. Otherwise, the focus is on the inherent quality and performance of the tips themselves, rather than extensive add-ons or modifications.
