Let’s Dive into VWR Maxi 20 Electrophoresis System E1120-30-1-V Combs 1 Mm x 30-Tooth Comb
The VWR Maxi 20 Electrophoresis System E1120-30-1-V Combs 1 Mm x 30-Tooth Comb is a key component in molecular biology labs, specifically designed for separating DNA or protein molecules based on their size and charge. Manufactured by VWR, this comb is part of the larger Maxi 20 Electrophoresis System, known for its high throughput capabilities and robust design. Its defining feature is the 30-tooth configuration with 1 mm well width, allowing for the simultaneous loading and analysis of numerous samples.
For years, my lab struggled with inefficient sample loading during electrophoresis. We were constantly battling well inconsistencies and low throughput when screening large numbers of samples. Upon receiving the VWR Maxi 20 Electrophoresis System E1120-30-1-V Combs 1 Mm x 30-Tooth Comb, I immediately noticed the precision of the comb’s teeth and its solid construction.
Compared to similar combs from Hoefer and Bio-Rad, the VWR comb felt more robust and the well spacing seemed more precise. This seemed like a perfect way to finally increase our lab’s efficiency. My initial excitement was met with a healthy dose of skepticism, as previous experiences with electrophoresis combs hadn’t always lived up to expectations.
Real-World Testing: Putting VWR Maxi 20 Electrophoresis System E1120-30-1-V Combs 1 Mm x 30-Tooth Comb to the Test
First Use Experience
The first test run involved analyzing PCR products from a 96-well plate for a high-throughput genotyping project. The VWR Maxi 20 Electrophoresis System E1120-30-1-V Combs 1 Mm x 30-Tooth Comb was placed into the casting tray, and agarose gel was poured around it. After the gel solidified, removing the comb was surprisingly smooth and created consistent, well-defined wells across the entire gel.
The ease of use was immediately apparent; the 1 mm well width provided ample space for loading samples, even with slightly viscous DNA solutions. One initial concern was whether the thin walls between the 30 teeth would be fragile, but they proved to be surprisingly durable during repeated loading.
Extended Use & Reliability
After months of consistent use, the VWR Maxi 20 Electrophoresis System E1120-30-1-V Combs 1 Mm x 30-Tooth Comb has proven to be remarkably durable. There has been no bending or warping of the teeth, even after repeated exposure to different buffers and gel formulations. Cleaning is easy, requiring only a quick rinse with distilled water.
Compared to previous combs that would often crack or develop imperfections over time, this one has held up exceptionally well. The consistent well formation has led to more reliable electrophoresis results and has significantly reduced the need to repeat experiments due to loading errors.
Breaking Down the Features of VWR Maxi 20 Electrophoresis System E1120-30-1-V Combs 1 Mm x 30-Tooth Comb
Specifications
Description: 1 mm x 30-Tooth Comb. This specifies the thickness of the comb, influencing well volume, and the number of sample wells it creates simultaneously.
Dimensions: 23W x 39.5L x 9H cm (91/16 x 159/16 x 31/2“). These dimensions define the size and compatibility of the comb with the VWR Maxi 20 Electrophoresis System.
Max Sample Capacity: 450 (when using compatible system components). This refers to the system’s ability to process many samples simultaneously, greatly increasing throughput.
These specifications are vital because they directly influence the system’s throughput, resolution, and compatibility with various experimental designs. The 30-tooth comb is particularly useful for labs needing to analyze large numbers of samples quickly and efficiently, such as in PCR product screening or RFLP analysis.
