Designed to replace hazardous razor blades !
The superior cutting edge of x-tracta allows for fast and accurate extractions of DNA and RNA bands from agarose gels.  Cross contamination is eliminated (no more razor blades).  Fast use allows for reduced UV damage of samples.  Easily transfer DNA to microcentrifuge tubes.

Extracting DNA or RNA from agarose gels is easy:
1.) Determine gel band of interest.
2.) Press the x-tracta into the gel, then slowly rock allowing its cutting edges to penetrate the gel.
3.) Transfer into a microcentrifuge tube by squeezing the bulb end of the x-tracta.

Testimonial from Researchers:

“x-tracta is so easy to use, I’ll never go back to razor blades.”

“I spend less time looking for my samples on the floor.”

“I don’t have to worry about burning my retina anymore.”

"Cross-contamination issues have now been eliminated at the gel extraction step."

“At last, a disposable tool you can use with one hand.”

"The device removes unnecessary safety risks to researchers

The x-tracta has evolved beyond historical and first generation gel extraction tools to provide disposability with one-handed operation. The proprietary cutting blade and ergonomic design means that extractions can be performed in a rapid two-step process with great accuracy and precision.

Historical Tools	Generation 1 Tools	x-tracta
Slow	Slow	Fast
Multi-step process	Three-step process	Two-step process
User dependent	Two-hand process	One-hand process
Variable results	Variable results	Excellent Results
Unsafe	Safe	Safe
Washing required	Disposable	Disposable
Low-failure rate	High-failure rate	Low-failure rate

Put simply, the superior cutting edge of x-tracta means that it just works better than any other gel extraction solution available.

Here's the proof.
