Gel Crusher™ Spin Column

Rapid Gel Fragmentation for DNA Recovery.

Gel Crusher™ Spin Columns provide a fast, efficient, and consistent method for gel fragmentation, replacing traditional crush-and-soak or manual gel breaker steps. Designed with 600 uM filtration pores, these columns enable quick and uniform fragmentation of agarose or acrylamide gel slices, saving time and increasing DNA recovery yields.

Ideal for workflows in molecular cloning, PCR cleanup, restriction digests, DNA sequencing, and labeling protocols, the Gel Crusher™ simplifies the preparation of gel fragments for downstream purification and elution steps.

Simply insert the Gel Crusher™ column into a 2 mL microcentrifuge tube, add your pre-cut gel slice (prepared using a gel cutter or razor blade), and centrifuge at max speed (~15,000 x g) for 5 minutes. The gel will be forced through the 600 uM pores, producing small, uniform fragments that can be easily pipetted using wide-bore tips into NaCl or other solutions.

This process creates a fine slurry that enhances elution efficiency and improves access to the target nucleic acids, significantly reducing incubation and processing time.

Key Features

• Efficiently breaks gel slices into uniform fragments
• Eliminates manual crush-and-soak steps
• Increases DNA yield and recovery efficiency
• Fits standard 2 mL microcentrifuge tubes
• Compatible with standard benchtop centrifuges (up to 15,000 x g)
• 600 uM pore size ideal for agarose or acrylamide gels
• Simplifies downstream processes: elution, filtration, incubation
• For use in PCR, cloning, digestion, sequencing, and more 

Reversible Racks
