Breaking Down the Features of VWR Midi Plus Horizontal Electrophoresis Systems E1115-18MC15 Combs 1.5 Mm x 18-Tooth Comb
Specifications
- Description: 1.5 mm x 18-Tooth Comb. This indicates the thickness of the gel and the number of sample wells the comb creates.
- Dimensions: 17.5W x 26.5L x 9H cm (67/8 x 107/16 x 317/32“). These dimensions ensure compatibility with the VWR Midi Plus Horizontal Electrophoresis System.
- Buffer Volume: 500 mL. This relates to the overall electrophoresis system and not specifically the comb; however, proper buffer volume is essential for optimal performance.
The 1.5 mm thickness is ideal for loading a larger volume of sample, which can be beneficial for visualizing faint bands. The 18-tooth design maximizes sample throughput, allowing for efficient analysis of multiple samples in a single run. The dimensions are critical for proper fit and function within the VWR Midi Plus system, ensuring consistent electric field distribution and optimal separation.
