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

• Choose 60 well (5 x 12) or 96 well (8 x 12) formats
• Reversible racks, accept 0.5 and 1.5 to 2.0 mL microtubes
• Alphanumeric marking on each well
• Made of polypropylene

Lab Armor® Beads

- Watch the video in the downloads tab to learn more! 

Lab Armor Beads are dry metallic beads that replace water/ice/oil/sand in baths, giving old equipment a cool, shiny, state-of-the-art upgrade. Eliminates water bath contamination, harmful germicides, and unpleasant maintenance. 

Beads are dry and naturally more resistant to microbial growth than water, and therefore, are less likely to harbor and contribute to transmitting microorganisms in the laboratory. 
  

Lab Armor Beads will help you save time and money. No more hassling with emptying, cleaning, and refilling water baths.

The bath stays on so there is no need to plan around warm-up times. Lab Armor Beads eliminate the worry about low water burnout because there is no water to evaporate.
 

Other Benefits of Lab Armor® Beads: 

• Cleaner working environment.
• Greater organization capabilities as samples are held in place without racks or other accessories.
• Environmentally friendly. 

Why Choose Lab Armor Beads?
 

Any Vessel, Any Angle

Lab Armor Beads prevent distorted data and dangers resulting from inaccurate temperatures, evaporated lab water baths, and water-exposed contaminated samples. The Beads are designed to decrease microbial contamination that can ruin experiments or lead to safety issues in the laboratory.

Organized and Secure

Lab Armor Beads flow fluidly and can conform to all sizes and shapes of vessels placed within the bath. Vessels that are prone to tipping over or floating away no longer require racks, floats, or bottleneck weights to secure them in place. Sample vessels can be conveniently buried into the beads to avoid temperature gradients associated with exposure to room temperature air. Bottles will rest on the surface and conical tubes will stay firmly in place in less than 1/2 inch of Beads.

Specifications

• Temperature range: -80°C to 180°C
• High thermal conductivity
• Non-toxic, non-vaporizing, antimicrobial
• No daily requirement for biocides, germicides, or other cleaners
• No gray water
• Smooth rounded shape allows fluidity and will conform to many sizes and shapes of vessels
• No racks, floats or weights required to hold items in place
• Recyclable*
• Weight 4 Lbs. (1.81 kg) per Liter 

*Must follow biohazard disposal protocols if beads have been used in biohazardous work.
