The Hoefer SUB20 Maxi-Standard Submarine Gel Electrophoresis Unit is designed for high-resolution analytical and preparative nucleic acid studies. With a large-format 20 × 20 cm gel tray and four comb positions, it accommodates high sample loads and enables excellent separation clarity, making it ideal for advanced genomic workflows and scale-up studies.
SUB20 supports up to 160 samples and includes multichannel-compatible combs, UV-transparent tray design, and buffer recirculation ports for consistent, controlled runs. A cooling port variant (SUB20C) is also available for labs requiring thermal management during extended runs.
Features & Benefits:
- Large-format tray: 20 × 20 cm tray provides ample space for high-resolution separation and up to four combs.
- Multichannel pipette compatible combs: Enable fast loading of up to 40 samples per comb.
- Color-coded, height-adjustable combs: Instantly identify comb thickness and control well depth with precision.
- Buffer recirculation ports: Connect to a peristaltic pump to maintain buffer pH and prevent ionic gradient formation during long runs.
- Colored loading strips: Improve visibility for easier and more accurate loading.
- UV-transparent running tray: Permits direct gel imaging without removing the gel from the tray.
- Side handles: Ensure safe, stable transport throughout the lab.
Included Components (SUB20):
- Buffer Chamber Assembly
- Safety Lid
- High Voltage Leads
- Running Tray with Casting Gates*
- Two 1 mm thick, 16-well combs
- Colored Loading Strips
- Two Buffer Recirculation Ports
*Casting gates efficiently seal the tray for gel casting without using tape.
Cooling Variant (SUB20C):
The SUB20C includes all features of the standard model, with the addition of integrated cooling ports for temperature regulation during long or high-voltage runs.
