Blue Transilluminator Replaces UV Transilluminator

"Wow! It's super easy."

"The combination of the blue transilluminator and the glasses makes it trivial. We leave the gel on the transilluminator, put on the glasses, and cut the band out with a knife. So much easier than dealing with UV. Love the simplicity. Anyone that wants to cut out bands needs the set up."

What makes our transilluminator different?

In 2009 we set out to build a high quality, affordable blue transilluminator. We built dozens of prototypes, tested them out in the lab, and sent early illuminators to our colleague's labs to get their thoughts.

The result is our Blue Transilluminator which sells for $399 (for a limited time, $449 normally). We designed it around 3 main principles:

  • Super sharp bands with blue light dyes: SYBRsafe, GelGreen, GRSafe
  • For gels for the most popular gel electrophoresis boxes like Owl Gel Box and Fischer equipment
  • Easy to put away when you're done using it

About Pearl Biotech

Hi, my name is Tito Jankowski, I helped design the Pearl Blue Transilluminator. I’m passionate about biotech research. Since I hope this blue transilluminator will be in your lab soon, I wanted to let you know a little bit about myself.

Amateur Botech Lab: I co-founded BioCurious, the world’s first hackerspace for biotech in Sunnyvale, California. Amazing things are happening, including a 3D bio-printer project, discovering new natural antibiotics, and an iGEM team working engineering yeast to produce cow’s milk called Real Vegan Cheese.

Open Source PCR machine: I also co-founded a company called OpenPCR, an open source PCR machine that anyone can build from a kit.

CES Design Award:Finally, I helped design the future of consumer medical devices at a company named Scanadu, out of NASA Ames Research Center in Mountainview, California. The product won “Best Innovation of 2013” in the Personal Electronics category, which is pretty cool!

My degree is in biomedical engineering from Brown University, I graduated in 2008 and started designing new lab equipment right after I graduated. Let's connect on LinkedIn

“OK, so what’s cool about blue transilluminators?” you ask. If every lab in the world ditched their UV transilluminator for a blue transilluminator, I’m convinced it would accellerate research substantially. It may seem like a small step, but DNA damage from UV Light causes tons of re-work, late nights in the lab, and just makes being a scientist frustrating. Norman Wang and I started Pearl Biotech working out of our apartments to make the tools for biotechnology easier to work with.

I’m proud to say that the Pearl Blue Transilluminator is used in hundreds of labs all over the world. Along the way, I’ve answered thousands of questions about blue transilluminators and gel imaging systems. Ask me your toughest question!

Do you dream of engineering biofuels and exploring your genome? So do we.

We make new tools for our work, not square pegs cut to fit round holes. At Pearl Biotech, we make bioengineering accessible by designing cool, smart equipment for the modern genetic explorer.

We get inspired by open access projects such as OpenWetWare and open hardware projects like the Arduino and Raspberry Pi. In fact, the original discussions for the Open Gel Electrophoresis Box project began on OpenWetWare. Of course, we wouldn’t be here without standing on the shoulders of giants.

The design of the Open Gel Electrophoresis Box and the Pearl Blue LED Transilluminator are a culmination of mind storming sessions, trial-and-errors, discussions with Kay Aull, Jonathan Cline, Mac Cowell, John Cumbers, Jim Hardy, Tito Jankowski, Michael Katsevman, Tom Knight, Meredith Patterson, Norman Wang, and many others who actively participated on the DIYBio Google Groups forum and gave their thoughts through the Open Gel Box 2.0 RFC, and Greg Fox and Owl Scientific for their inspiring work and unique gel casting method.
