Happy Anniversary Plexon!

Plexon’s newsletter from January 30, 2013 discussing Plexon’s 30th anniversary.



January 30, 2013

Plexon is thrilled to be celebrating its 30th year completely dedicated to research labs. We are honored to call scientists in thousands of labs throughout forty countries our friends and customers. It brings us great joy to have pioneered and led the market for decades . . . but that was only the beginning!

We have many exciting innovations to share this year. As 30 years is an incredible milestone – and being the first company in neural data acquisition to achieve it – we are throwing a year-long celebration! Join the festivities by taking part in our special product promotions and the JoVE Publication Grant Contest. We have also begun featuring recent publications from our customers in the new Research Spotlight section of this newsletter – all of whom can get free stuff from Plexon (see below).

Thank you to all of our customers, our distributors in the far corners of the globe, our government collaborators, and our industry partners for making it happen. We are looking forward to being your most reliable, innovative and dedicated research partner for the next 30 years and beyond!

Optogenetics at SPIE Photonics West 2013

Plexon announces its sponsorship of the Optogenetics and Hybrid-Optical Control of Cells program next month at SPIE Photonics West. Senior Research Engineer, Isaac Clements, serves on the program committee and will presenting his latest poster “Miniaturized LED sources for in vivo optogenetic experimentation.” Stop by February 3 at 3:00 p.m., Hall A, BiOS Expo to learn more about the latest in Plexon’s PlexBright™ Optogenetic Stimulation line of products from the lead engineer himself!

Harvey Speaks at the National University of Singapore

Harvey Wiggins, Plexon’s President, started the 30th year off with a bang – spending a couple weeks on the road in Asia. While there, he was honored to be a guest speaker at the National University of Singapore. His lecture entitled “Architecture and Design of High Channel Count Neural Data Acquisition Systems” was hosted by the Department of Electrical and Computer Engineering and enjoyed by an eager crowd.

Research Spotlight

Welcome to the inaugural Research Spotlight. Plexon is thrilled to highlight the innovative and insightful discoveries of our amazing customers. Not only will we recognize your good work in this newsletter but when you mention Plexon equipment used in your article and let us know about it at publications@plexon.com, we will send you a thank you award – a mug and a T-shirt.

You may recall that Plexon’s primary color is blue. We have now added a green accent to represent the energy of life. This years’ T-shirts and mugs will be available in limited-edition, 30th Anniversary commemorative green. . . then back to blue forevermore.

4th Annual Plexon Neurophysiology Workshop

Make plans to join us April 29-May 2 for the annual workshop . Registration is limited to 40 people to ensure an extensive, hands-on experience. An agenda featuring national and international speakers will be available in the coming weeks. Email workshop@plexon.com with any questions.

Enhanced Technical Support

Customer support is one of our highest priorities. Although we are thankful for the rapid growth over the recent years –customers and new products, we recognize that it has impacted the performance of our support team. Accordingly, we have recently expanded the team, and now announce extended hours starting earlier at 8:30 a.m. central time. We hope you find the enhancements to be effective, and encourage comments about your experience to be sent to me at stacie@plexon.com.

Plexon is Hiring Again

Plexon grew its team more than 25% last year, and we are still going strong. We have two additional positions now posted and are looking for a global technical sales candidate for the behavioral research market, and a neuroscience writer. Send resumes to jobs@plexon.com.
