VWR Midi Plus Horizontal Electrophoresis Systems E1115-18MC-1 Combs 1 Mm x 18-Tooth Comb, Each Review

The VWR Midi Plus Horizontal Electrophoresis Systems E1115-18MC-1 Combs 1 Mm x 18-Tooth Comb, Each: Final Thoughts from Me

As an outdoor and tactical gear specialist with over a decade of experience, I’ve seen my fair share of specialized equipment. However, my background also includes significant time in the lab, which gives me a unique perspective on tools like the VWR Midi Plus Horizontal Electrophoresis Systems E1115-18MC-1 Combs 1 Mm x 18-Tooth Comb, Each. This seemingly simple comb is a critical component in gel electrophoresis, a technique fundamental to molecular biology and biochemistry.

I needed to upgrade the combs for our lab’s existing electrophoresis system to accommodate higher throughput. The 18-tooth design of this comb promised to be a significant improvement over our older 12-tooth combs. Upon unboxing, the VWR comb felt solid, well-constructed, and precise; the teeth were uniformly spaced and sharp.

We also considered combs from Bio-Rad and Thermo Fisher Scientific. Ultimately, we chose the VWR option due to its attractive price point and the positive reviews regarding its compatibility with our VWR Midi Plus system. My initial impression was one of cautious optimism; I was excited about the potential for increased efficiency, but I was also wary of potential issues with gel loading and sample resolution.

Real-World Testing: Putting VWR Midi Plus Horizontal Electrophoresis Systems E1115-18MC-1 Combs 1 Mm x 18-Tooth Comb, Each to the Test

First Use Experience

The first time I used the VWR Midi Plus Horizontal Electrophoresis Systems E1115-18MC-1 Combs 1 Mm x 18-Tooth Comb, Each, it was during a crucial DNA fragment separation experiment. We were analyzing PCR products generated for a wildlife genetics study, and accurate sizing was essential. The comb fit snugly into the gel casting tray of our VWR Midi Plus system.

The 18-tooth design initially felt a bit crowded compared to our old combs. However, using a multichannel pipette, I quickly adapted to the denser well arrangement, and the loading process became surprisingly efficient. There were no issues with the comb damaging the gel during insertion or removal, and the resulting wells were clean and well-defined.

Extended Use & Reliability

After several weeks of consistent use, the VWR comb has proven to be a reliable workhorse in our lab. It shows no signs of wear and tear, despite being used multiple times per week. Cleaning the comb is straightforward: a simple rinse with distilled water and a gentle wipe with a soft cloth is usually sufficient.

The comb’s performance has been consistently excellent. The wells it creates provide excellent sample resolution, and we have observed minimal band distortion, even when loading relatively large volumes. Compared to our previous experience with cheaper, generic combs, the VWR comb is a significant upgrade, offering improved precision and durability.
