GENETIC scientists have instant access to the tools of their trade thanks to a vending machine.

The system, known as the Helena Smartstore, combines a vending machine, smart card technology and wireless communications.

It stocks up to 40 enzymes and reagents, the tools scientists need to manipulate DNA in molecular biology.

It was developed by Newcastle's G2 Integrated Solutions, which specialises in smart card applications, and biotech companies Helena Biosciences, in Sunderland, which supplies hospitals, research institutes and universities with molecular biology products.

Dr David Snell, European innovations and product development manager for Helena Biosciences, said: "We are delivering a unique new system that really delivers its promises through a combination of design, effective technology and customer servicing."

It stores the products at temperatures of 20C in a vending machine. Scientists access them with a pre-paid smart card.

This means valuable research time is not lost waiting for deliveries or for institute stores to open.

Having the materials delivered in dry ice would cost £65 a time. The system is being used at research institutes in Newcastle and Birmingham universities, and the London School of Hygiene and Tropical Medicine.

"The first three machines have proved the concept and we are very excited about the future," said Dr Snell.

Nigel Hope, G2's technical director, said: "The idea of cashless vending for the molecular biology industry is a perfect example of our technology and innovation enhancing the way we live and work."
