Our Company

William Laboratories was acquired by Temptime Corporation in 2013 and relocated to Temptime headquarters in Morris Plains, New Jersey. Since 2001, William Labs has been focused on developing and marketing FDA-regulated products in the area of temperature monitoring for blood products. These products are based on irreversible temperature indicators that are especially suited to monitoring of blood products. The Safe-T-Vue brand is its premiere temperature-indicating product, and has held a place in the market for over two decades.
