Chemical verification and identification company Centice, which is making headway into law enforcement and security applications, has closed on $8 million in financing.

The Morrisville company said today that the series D round included both new and existing investors. The financing includes equity investments as well as conversion of debt. Last August, Centice announced it had raised $1 million in convertible debt financing. Centice has developed devices that identify chemicals in a given sample. The technology was originally developed for pharmacies. By verifying a drug’s identity, the device would reduce prescription errors.

In 2011 Centice started to expand its scope to include law enforcement. The company has since brought to market devices that police and narcotics officials can use to identify controlled prescription drugs and illegal narcotics.

Centice said that the latest round will be used to increase sales and distribution of its mobile narcotics identification system as well as to develop new products. The mobile product, called the Mobile Field La-3000, enables officials to quickly identify more than 3,600 controlled prescription drugs, street narcotics and agents used to cut drugs. The technology brings to officers in the field drug analysis capabilities that had previously been available only in laboratory settings.

“Our 2013 plan is very aggressive and we will continue to add new features and improvements to MFL- 3000 as well as develop new products that leverage our technology,” Centice CEO & President Prasant Potuluri said in a prepared statement. “This additional financing shows continued confidence in our strategic direction and the success of the MFL-3000 in the market place.”

Centice’s technology is based on research from Duke University. The company was founded in 2004.
