Let’s Dive into VWR Maxi 20 Electrophoresis System E1120-40MC-1 Combs 1 Mm x 40-Tooth Comb
The VWR Maxi 20 Electrophoresis System E1120-40MC-1 Combs 1 Mm x 40-Tooth Comb promises high-throughput sample processing and resolution, crucial for labs handling large numbers of samples. Manufactured by VWR, this system, particularly the comb, aims to streamline PCR product analysis, RFLP analysis, and plasmid screenings. Its durable design is tailored for the everyday demands of a busy laboratory, making it an attractive option for researchers.
My journey to finding the VWR Maxi 20 was born out of necessity; my lab was struggling with low throughput using our old electrophoresis system. We needed a system capable of handling the influx of samples from our recent high-volume COVID-19 research project. I remember the frustration of manually loading gels, a painstaking process that ate up valuable time and increased the risk of error.
The VWR Maxi 20 arrived neatly packaged. The comb itself looked robust, made of a thick, clear acrylic. Compared to our previous system which had flimsy combs prone to bending, the VWR‘s comb felt like a serious upgrade.
We were using a Bio-Rad system before this one and debated upgrading to a newer Bio-Rad model, or even a Thermo Fisher system. However, after carefully reading the product descriptions, and analyzing the features of VWR Maxi 20 Electrophoresis System E1120-40MC-1 Combs 1 Mm x 40-Tooth Comb, we decided to go with VWR, because of the cost and features.
Initial impressions were good; the system looked well-built and professional, the comb seemingly able to handle the throughput we were aiming for. My excitement stemmed from the potential time savings and improved accuracy that this system could bring to our research.
Real-World Testing: Putting VWR Maxi 20 Electrophoresis System E1120-40MC-1 Combs 1 Mm x 40-Tooth Comb to the Test
First Use Experience
The first time I used the VWR Maxi 20, it was to analyze a batch of PCR products from a 96-well plate. I tested the comb with a carefully prepared gel and buffer solution. The lab environment was controlled, with a consistent temperature and humidity.
The VWR Maxi 20 performed well under these conditions. It offered us us smooth gel and buffer transfer and the comb was easy to install and remove without disrupting the wells. My main concern going in was well leakage, but there was no leakage at all.
Using the VWR Maxi 20 and the 40-tooth comb drastically reduced the time it took to load samples. There were no issues in loading, and the sample placement was perfect, minimizing the risk of cross-contamination. The “EasyLift” gel box lid, was easily removed using the side tabs and pressure pads.
Extended Use & Reliability
After a few months of continuous use, the VWR Maxi 20 Electrophoresis System has proven to be a reliable workhorse. The acrylic construction of the gel box and tray has held up remarkably well, with no signs of cracking or leaking. The 1 mm x 40-tooth comb shows no warping or bending, despite constant use.
Maintenance is straightforward. Regular cleaning with mild soap and water keeps the system in good condition. The platinum electrode cassettes are easily removable for cleaning or replacement, a feature that significantly simplifies upkeep.
Compared to our previous Bio-Rad system, the VWR Maxi 20 has significantly boosted our throughput and reduced the risk of errors. The robust construction and easy maintenance have made it a superior choice for our laboratory.
Breaking Down the Features of VWR Maxi 20 Electrophoresis System E1120-40MC-1 Combs 1 Mm x 40-Tooth Comb
