Let’s Dive into VWR Midi 10 Electrophoresis System E1110-16-0.7 Combs 0.75 Mm x 16-Tooth Comb
The VWR Midi 10 Electrophoresis System E1110-16-0.7 Combs 0.75 Mm x 16-Tooth Comb, a vital component from VWR, is designed for labs needing efficient and reliable sample processing. This comb, specifically, caught my eye for its potential to streamline our workflow, especially when dealing with large batches of DNA or protein samples.
Our lab recently faced a bottleneck in gel electrophoresis. We needed a system that could accommodate more samples per run without sacrificing resolution.
The comb arrived securely packaged. My initial impressions were positive, noting the seemingly durable acrylic construction and precise tooth formation.
I also considered the Thermo Scientific Owl EasyCast B2 Mini Gel Electrophoresis System and the Bio-Rad Mini-PROTEAN Tetra System. The VWR system’s compatibility with our existing power supplies and its reputation for consistent results swayed my decision.
I was initially optimistic, hoping this comb would be a simple yet effective upgrade. The prospect of running more samples simultaneously was certainly exciting.
Real-World Testing: Putting VWR Midi 10 Electrophoresis System E1110-16-0.7 Combs 0.75 Mm x 16-Tooth Comb to the Test
First Use Experience
I tested the comb in our standard molecular biology lab setup. The experiments involved separating DNA fragments amplified via PCR.
The lab environment was typically climate-controlled. However, the humidity fluctuates during sterilization cycles, which could potentially affect gel polymerization.
The comb was surprisingly easy to use. Its design allowed for quick and precise placement in the gel casting tray.
One minor issue arose: the initial gel casting attempt resulted in slight leakage around the comb. This was quickly resolved by ensuring a tighter seal between the comb and the casting tray.
Extended Use & Reliability
After several weeks of consistent use, the comb has proven to be remarkably durable. There are no visible signs of wear or tear on the acrylic.
Cleaning is a breeze. A simple rinse with distilled water and a gentle wipe with a lint-free cloth are sufficient to remove any residual gel.
This comb has significantly outperformed our previous combs in terms of sample throughput. It has also provided more consistent and well-defined bands.
Breaking Down the Features of VWR Midi 10 Electrophoresis System E1110-16-0.7 Combs 0.75 Mm x 16-Tooth Comb
Specifications
The VWR Midi 10 Electrophoresis System E1110-16-0.7 Combs 0.75 Mm x 16-Tooth Comb boasts several key specifications. It features a 0.75 mm tooth thickness.
The comb contains 16 teeth. This allows for the loading of 16 samples per row.
The entire system’s dimensions are 12.5W x 22L x 9H cm (31/2 x 81/4 x 31/2“). This compact footprint maximizes bench space.
The system requires a buffer volume of 300 mL. This relatively low volume conserves resources.
The maximum sample capacity is 100. This high throughput is ideal for labs processing numerous samples.
These specifications are critical for efficient and accurate electrophoresis. The tooth thickness determines the well volume and thus the amount of sample that can be loaded. The number of teeth dictates the sample throughput, and the buffer volume influences the run time and resolution.
Performance & Functionality
The VWR Midi 10 Electrophoresis System E1110-16-0.7 Combs 0.75 Mm x 16-Tooth Comb performs exceptionally well in its intended application. It consistently produces sharp and well-resolved bands.
One minor weakness is the potential for slight leakage during gel casting. This can be mitigated by careful attention to sealing the comb properly.
It has exceeded my expectations. The increased sample throughput has significantly improved our lab’s efficiency.
Design & Ergonomics
The build quality is excellent. The comb is constructed from thick, durable acrylic.
It is very user-friendly. The design is intuitive and requires minimal setup time.
Durability & Maintenance
Based on its construction and performance so far, the comb should last for a long time. Simple routine cleaning should ensure years of reliable service.
Maintenance is straightforward. As mentioned previously, a quick rinse and wipe are typically all that is needed.
Accessories and Customization Options
The comb is part of the VWR Midi 10 Electrophoresis System. Other accessories include gel trays, electrode cassettes, and visualization strips.
The system is compatible with various gel concentrations and buffer systems. Users can also adjust the voltage and run time to optimize separation.
Pros and Cons of VWR Midi 10 Electrophoresis System E1110-16-0.7 Combs 0.75 Mm x 16-Tooth Comb
