Ready to Know the Truth About the VWR Midi Plus Horizontal Electrophoresis Systems E1115-12-1.5 Combs 1.5 Mm x 12-Tooth Comb?
The VWR Midi Plus Horizontal Electrophoresis Systems E1115-12-1.5 Combs 1.5 Mm x 12-Tooth Comb, offered by VWR, is a critical component for molecular biology and biochemistry labs needing to separate DNA or RNA fragments. This comb, specifically designed for the VWR Midi Plus Horizontal Electrophoresis System, creates 12 wells with a 1.5 mm thickness, allowing for efficient sample loading and clear band resolution. It’s an essential tool, but is it worth the price tag of $403.99?
As a seasoned lab specialist, I’ve encountered countless electrophoresis systems and their associated components. My quest for this particular comb arose from the need to optimize our lab’s throughput without sacrificing the quality of separation. The ability to load more samples in a single run, while maintaining adequate well volume and band resolution, was paramount.
Unboxing the comb, my first impression was one of sturdy, well-molded construction. The acrylic material felt robust, promising durability against the rigors of daily lab use. Compared to some cheaper, flimsier combs I’ve used in the past, this felt like a significant step up, suggesting it might avoid the common issue of warping or cracking after repeated autoclaving.
Having previously used similar combs from other manufacturers like Bio-Rad and Invitrogen, I was curious to see how this VWR comb would stack up. The Invitrogen combs, while reliable, were often significantly more expensive. The Bio-Rad combs, while a closer price point, sometimes suffered from inconsistent well formation. I chose the VWR comb hoping for a sweet spot of quality and value.
My initial excitement was tempered with a bit of healthy skepticism, given the price. However, the build quality gave me hope that this comb could indeed be a worthy investment for our lab. Would it deliver on its promise of efficient sample loading and reliable performance? Only time, and rigorous testing, would tell.
Real-World Testing: Putting VWR Midi Plus Horizontal Electrophoresis Systems E1115-12-1.5 Combs 1.5 Mm x 12-Tooth Comb to the Test
First Use Experience
My first test of the VWR Midi Plus Horizontal Electrophoresis Systems E1115-12-1.5 Combs took place in our standard molecular biology lab setup. I used it to separate PCR products of varying sizes, a common task in our workflow. The comb slid smoothly into the gel tray slots, aligning perfectly without any wobble or awkward fit.
I ran the electrophoresis under standard conditions (100V for 45 minutes) and monitored the separation. The bands were sharp and well-defined, demonstrating good resolution. Loading the samples was straightforward thanks to the 1.5 mm thickness, preventing any accidental well overflows or cross-contamination.
Extended Use & Reliability
After several weeks of consistent use, the VWR comb has proven to be a reliable workhorse. I’ve run over 50 gels with it, separating everything from small RNA fragments to larger DNA constructs. It has shown no signs of wear and tear.
Cleaning is simple, requiring only a quick rinse with distilled water after each use. I also autoclaved it several times, and it maintained its shape and integrity without any warping or cracking. Compared to some of the older combs in our lab, which have become brittle and prone to breaking, the VWR comb definitely stands out in terms of durability.
