New x-tracta agarose gel tool gives you cleaner DNA in less time and with less effort. This disposable tool cleanly cuts and picks up uniform gel slices, eliminating possible cross-contamination from razor blades, tweezers, or other gel cutting methods. The process is quick, reducing the time that both you and your DNA samples are exposed to UV light. Slippery gel bands are contained in the device until you release them, and can be transferred directly to microcentrifuge tubes for the next extraction step. 100/pack.

• Eliminates cross contamination
• Minimizes UV damage to samples
• Creates uniform gel slices every time
• Replaces hazardous blades
