Let’s Dive into Corning Falcon Round-Bottom Tubes, Disposable, Polystyrene, 352017 14 Ml Tubes
The Corning Falcon Round-Bottom Tubes, Disposable, Polystyrene, 352017 14 Ml Tubes from BD Biosciences are ubiquitous in laboratory settings, but often overlooked in terms of their impact. These aren’t your high-tech gadgets; they’re the unsung heroes holding the very foundation of scientific research, testing, and analysis. Their disposable nature offers a crucial advantage in environments demanding sterility and preventing cross-contamination.
My work in biohazard containment and mobile testing units often presented challenges with maintaining sample integrity in uncontrolled environments. We needed reliable, disposable containers that could withstand some abuse and reliably hold biological samples. We experimented with various tubes, and the Corning Falcon Tubes consistently proved to be the most dependable.
My initial thought upon opening a fresh bag of these tubes was, “These are exactly what I expected and need.” They feel sturdy enough for their intended purpose, and the round bottom is perfectly suited for centrifuge use. Their optical clarity is good for visual sample inspection, and the included polyethylene snap caps give secure closure.
Compared to other brands, such as Eppendorf tubes which are typically smaller and more expensive, or generic polystyrene tubes which often lack consistent quality, the Corning Falcon Tubes strike a sweet spot. They’re affordable enough for large-scale use while maintaining a level of quality that inspires confidence. We had tried some off-brand tubes previously and the inconsistent wall thickness led to several failures during centrifugation – a costly mistake.
My first impression was positive, with a slight hint of relief; these tubes are a no-nonsense solution. They might not be flashy, but they’re essential tools that perform their job reliably, allowing me to focus on the science rather than worrying about sample containment. For the price of $349.99 they are an investment, however, a solid investment.
Real-World Testing: Putting Corning Falcon Round-Bottom Tubes, Disposable, Polystyrene, 352017 14 Ml Tubes to the Test
First Use Experience
My primary testing ground for these tubes was in a mobile testing lab during a field study assessing water quality near agricultural runoff. We needed to collect water samples and process them on-site using portable centrifuges. The Corning Falcon Tubes were crucial for sample collection and preparation for various tests.
The conditions were far from ideal; temperature fluctuations, humidity, and the ever-present risk of contamination were constant challenges. Even in these conditions, the tubes performed admirably. The snap caps provided a secure seal, preventing leaks even when the tubes were jostled during transport on rough roads.
Using the tubes was straightforward. Filling, capping, labeling, and centrifuging were all easy, requiring no special handling. The rounded bottom made pelleting easy and resuspension efficient.
The only minor issue I encountered was the lack of graduations on the tube itself. While not a deal-breaker, having printed volume markings would have been a convenient addition. We adapted by using pre-marked transfer pipettes.
Extended Use & Reliability
After several weeks of continuous use in the field and subsequent analysis in the lab, the Corning Falcon Tubes continued to hold up well. There were no signs of degradation, such as cracking or clouding, despite repeated centrifuging and exposure to various chemicals.
The tubes demonstrated consistent durability, holding their shape even after multiple uses. The snap caps retained their sealing ability, proving to be more resilient than I initially anticipated.
Maintenance was minimal; after use, the tubes were discarded, eliminating the need for laborious washing and sterilization. This was a significant advantage in terms of time savings and reducing the risk of cross-contamination.
In comparison to previous experiences with less expensive alternatives, the Corning Falcon Tubes are a clear winner in terms of reliability and durability. The peace of mind they provide, knowing that samples are securely contained and won’t be compromised, is well worth the investment. They are a true improvement over the off brand options.

Performance & Functionality
The Corning Falcon Tubes excel in their primary function: reliable sample containment. Their polystyrene construction offers a good balance of clarity and chemical resistance. The snap caps create a tight seal, minimizing the risk of leaks.
The tube’s strengths lie in their consistent quality and ease of use. Centrifugation performance is excellent, and the tubes are compatible with most standard lab equipment. The major weakness is the lack of volume markings, though this is a minor inconvenience that can be easily addressed.
The tubes meet and exceed expectations for a standard disposable lab tube. The durable construction and reliable sealing provide confidence in the accuracy and integrity of experimental results.
Design & Ergonomics
The design is simple and functional, with a rounded bottom that facilitates pelleting and resuspension. The polystyrene material is lightweight and easy to handle. The lack of graduations is the only ergonomic drawback.
The tubes are user-friendly and require no special training or handling techniques. The snap caps are easy to open and close, even with gloved hands.
Durability & Maintenance
Given proper care, these tubes are expected to last through multiple uses within a single experiment. While designed for single use, the robust construction allows for careful reuse when necessary.
Maintenance is virtually nonexistent, given the disposable nature of the tubes. This eliminates the time and expense associated with washing and sterilizing reusable tubes.
Accessories and Customization Options
The Corning Falcon Tubes themselves do not have a wide range of accessories. However, they are compatible with standard centrifuge rotors and tube racks.
One could consider using different colored snap caps for easy sample identification or applying adhesive labels for detailed information. The tubes are also compatible with various types of sealing films, offering additional protection against contamination.
