What Makes the VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb Stand Out?
The VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb is a critical component for anyone using VWR‘s mini horizontal electrophoresis systems, facilitating efficient and precise DNA or protein separation. These combs, designed to create wells in agarose or polyacrylamide gels, are essential for loading samples prior to electrophoretic separation. The standout feature of this particular comb is its 1.5 mm thickness and 12-tooth design, allowing for larger sample volumes and increased throughput compared to other comb options.
As a gear specialist, my experience doesn’t typically involve lab equipment. However, a friend running a small genetics research lab mentioned their struggles with inconsistent gel loading and asked for my help finding a reliable and efficient comb.
Upon unboxing, I was immediately impressed by the apparent quality of the VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb. The acrylic felt solid and well-molded, and the individual teeth were evenly spaced and cleanly formed, hinting at precise well creation.
Compared to some generic combs they had been using, the VWR comb felt far more robust and the 1.5mm thickness was a definite advantage for their larger sample volumes. They had previously considered combs with more teeth, but the 12-tooth design seemed like a good balance between throughput and well size for their specific needs. My initial excitement stemmed from the promise of improved accuracy and efficiency in their gel electrophoresis workflow.
Real-World Testing: Putting VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb to the Test
First Use Experience
My friend’s lab immediately integrated the VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb into their standard DNA electrophoresis protocol. They tested it with both 7x7cm and 7x10cm gels, fitting the VWR mini systems perfectly.
They reported a significant improvement in well formation compared to their old combs; the wells were more uniform and had cleaner edges, even when using viscous samples. The ease of use was also notable; no specialized techniques were needed, it simply fit into their existing gel casting procedure. The only initial surprise was realizing how much larger the wells were compared to their previous combs, necessitating a slight adjustment in sample loading volume.
Extended Use & Reliability
After several weeks of consistent use, the VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb continued to perform reliably. The comb showed no signs of warping or cracking, even after repeated exposure to electrophoresis buffers and gel solutions.
Maintenance was straightforward, requiring only a rinse with distilled water and occasional cleaning with a mild detergent. My friend mentioned that it has outperformed their previous combs, which often developed cracks or chipped teeth after only a few uses, leading to inconsistent results.
Breaking Down the Features of VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb
Specifications
- Description: 1.5 mm x 12-Tooth Comb. This defines the thickness of the comb, dictating well volume, and the number of wells created in the gel.
- Dimensions: 9W x 21L x 9H cm (31/2 x 81/4 x 31/2“). These dimensions ensure compatibility with the VWR mini horizontal electrophoresis systems.
- Buffer Volume: 225 mL (This is the typical buffer volume for the mini electrophoresis system, not specifically the comb, but important context).
These specifications directly impact the usability and efficiency of the electrophoresis process. The 1.5 mm thickness allows for loading larger sample volumes, critical for detecting low-concentration DNA or protein.
Performance & Functionality
The VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb performs its primary function of creating consistent and well-defined wells with exceptional reliability. The even spacing and smooth finish of the teeth ensure uniform sample loading and prevent band distortion during electrophoresis.
A minor weakness could be that the 1.5mm thickness may not be ideal for researchers requiring very narrow bands or using very small sample volumes, but this is a trade-off for its ability to accommodate larger volumes. Overall, it exceeds expectations for ease of use and consistency.
Design & Ergonomics
The VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb is made from durable acrylic, which provides a balance between rigidity and chemical resistance. The comb’s design is straightforward and functional, with a comfortable grip for easy insertion and removal from the gel.
There is virtually no learning curve; it’s designed to integrate seamlessly into existing electrophoresis workflows.
Durability & Maintenance
Given the VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb’s construction, it should last for years with proper care. Cleaning involves only rinsing and occasionally using a mild detergent; avoid harsh chemicals or abrasive cleaners.
Damage to the teeth would render it unusable, so careful handling is important.
Accessories and Customization Options
The VWR Mini Horizontal Electrophoresis Systems E1107-12MC15 Combs 1.5 Mm x 12-Tooth Comb itself doesn’t have customization options, as it is a specific component for the VWR mini electrophoresis system. However, the system is designed to accommodate different comb sizes and tooth configurations depending on the specific application.
It is also compatible with various gel casting accessories and electrophoresis buffers commonly used in molecular biology labs.
