Hungry scientists taking a trip to the vending machine for refreshments may soon find Taq polymerase and IPTG next to their Coke and M&Ms. Helena BioSciences of Sunderland, UK
http://www.helena-biosciences.com has developed the Smartstore, a -20°C reagent-vending system for 40 Eppendorf and Fermentas reagents. The machine, which is accessed via a cashless "smartcard" that can also track inventory wirelessly, is offered free-of-charge to research institutes, and reagent restocking is also provided for free by Helena – the only charge is for the reagents themselves.
