The new spout will increase sap yields by 50 to 90 percent per tree.
The check valve technology was invented by Timothy Perkins, director of the Proctor Maple Research Center. It employs a valve -- a small ball that rolls back and forth in a chamber within the spout -- to block the flow back into the tree of sap containing bacteria.
All tapped maple trees pull sap back into their tap holes, as they try to balance the negative pressure established both by natural process and by vacuum tubing systems, which are pervasive in the industry. Bacterial backflow in turn causes the tree’s natural defense system to wall off the contaminated area of the tap hole, essentially plugging it and ending a sugarmaker’s season. Such walling off typically occurs late in the season.
By allowing the tree’s sap to continue to flow, the new spout will extend the sugarmaking season by one-and-a-half to two-and-a-half weeks, according to testing conducted by the Proctor and confirmed by Leader’s field testing. The sugaring season is typically four weeks long.
1 million advance orders
Although Leader has not yet listed the spout in its catalog or on its web site, the company has already received 1 million advance orders. Leader is projecting sales of three million units this maple season, making the spout its number one selling product. In the future, sales could be significantly higher.
According to Gary Gaudette, president of Leader Evaporator, the check valve spout could have a revolutionary impact on the maple industry.
“It’s going to add as much to syrup and sap production as vacuum tubing did.
I’m confident that this is going to be the thing to use in the future.” There are between 50 and 55 million taps in use in North America, Gaudette said.
Both Leader and Progressive Plastics are in hiring mode despite the recession, leadership at both companies said, and both anticipate the new spout will add further to their need to bring on new staff.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
