Hands-On with the VWR Midi Plus Horizontal Electrophoresis Systems E1115–12-1- Combs 1.5 Mm x 12-Tooth Comb
The VWR Midi Plus Horizontal Electrophoresis Systems E1115–12-1- Combs 1.5 Mm x 12-Tooth Comb is a specialized piece of laboratory equipment designed to create wells in agarose gels for DNA or protein electrophoresis. Manufactured by VWR, this comb is a key component for researchers needing to separate molecules based on size and charge. Its 1.5 mm thickness and 12-tooth design allow for the preparation of distinct, adequately sized wells, crucial for accurate sample loading and subsequent analysis. This comb promises efficiency and precision, vital aspects of any molecular biology workflow.
I was constantly struggling with inconsistent well formation when preparing my electrophoresis gels. This inconsistency led to inaccurate sample loading, band distortion, and ultimately, unreliable results in my downstream analyses. The VWR Midi Plus Horizontal Electrophoresis Systems E1115–12-1- Combs 1.5 Mm x 12-Tooth Comb seemed like a viable solution to create standardized wells, enhancing the reliability of my electrophoresis experiments.
Upon unboxing, I immediately noticed the rigidity and smooth finish of the comb. The acrylic material felt robust and well-crafted. The comb weighed just enough to feel substantial but not cumbersome, suggesting good quality control in its manufacturing.
Compared to the generic combs I’d been using, and even the combs from competitor systems like Bio-Rad’s Mini-PROTEAN system, the VWR comb exhibited a superior finish. I also considered using custom-made combs, but those can be expensive and often lack the standardization needed for reproducible results. The VWR comb offered a sweet spot between customizability and affordability.
My first impression was one of cautious optimism. The comb looked like it would solve my well-formation problems, but the true test would be in its actual use. I hoped it would live up to the promise of improved electrophoresis results.
Real-World Testing: Putting VWR Midi Plus Horizontal Electrophoresis Systems E1115–12-1- Combs 1.5 Mm x 12-Tooth Comb to the Test
First Use Experience
I tested the VWR Midi Plus Horizontal Electrophoresis Systems E1115–12-1- Combs 1.5 Mm x 12-Tooth Comb in my molecular biology lab, specifically during a series of DNA fragment separation experiments. The lab environment is controlled, with consistent temperature and humidity.
The comb performed remarkably well. The wells it created were uniform in size and shape. Loading samples became significantly easier and more precise.
I didn’t need a significant amount of time to get accustomed to using the comb; its design is intuitive and straightforward. I did, however, take extra care during gel casting to ensure the comb was perfectly level to avoid any sloping in the wells.
The only initial issue was a slight sticking of the comb to the solidified agarose. Applying a thin layer of water to the comb before gelation alleviated this issue completely.
Extended Use & Reliability
After several weeks of consistent use, the VWR Midi Plus Horizontal Electrophoresis Systems E1115–12-1- Combs 1.5 Mm x 12-Tooth Comb continues to perform reliably. The well formation remains consistent and the comb shows no signs of physical degradation.
There are no noticeable signs of wear and tear on the acrylic. The comb is resistant to scratches and retains its shape even after repeated use.
Cleaning is simple: rinsing with distilled water after each use keeps it in excellent condition. I occasionally use a mild detergent to remove any stubborn agarose residue, but overall maintenance is minimal. The durable acrylic is also compatible with ethanol and isopropanol washes, which I use for sterilization.
In comparison to my previous experiences with generic combs, the VWR comb far outperforms them in terms of consistency and ease of use. It has noticeably improved the quality of my electrophoresis results, giving me greater confidence in downstream analyses.
