Whitehouse Labs purchases CSZ Z-Plus Test Chambers to Expand Package Testing Services

Independent testing laboratory, Whitehouse Laboratories announces another major capital investment for its Package Testing Laboratory. Responding to growing demands from life science companies, this investment centers on an increase in environmental chamber storage space that will enable a much larger volume of packaging environmental conditioning and product storage to be performed – increasing capacity and reducing testing times. This second stage of major capital expenditure has already taken place with the recent purchase of two high performance environmental chambers from Cincinnati Sub-Zero (CSZ)

CSZ's Z-Plus Test Chambers are capable of simulating a wealth of temperature and humidity conditions with performance ranging from -73C to +170C and full relative humidity control allowing the lab to allow our lab to pre-condition products to simulate any shipping environment.  Each unit is fully-programmable and capable of a variety of tests, from basic thermal cycling to accelerated stress testing.  The equipment complements the Package Testing Laboratory’s existing units from CSZ.  Packaged-product environmental conditioning queue times can now be reduced with the added capacity – which is a benefit to all our valued clients.

 “We have a strong focus on reinvestment in our Package Testing Lab and this investment as a way to improve our service offering to current and future clients,” states Package Lab Director Eric Creveling. “We understand the challenges our clients’ face to meet manufacturing and product launch deadlines.  These chambers allow us to reduce lab testing queue times, to execute packaging design and validation projects more efficiently so that our clients’ can reduce their time to market.”

When asked about the relationship with Whitehouse Laboratories, Cincinnati Sub-Zero’s Jeff Sterbling, Regional Manager said, “We began our relationship with Whitehouse Labs eight years ago supplying a high performance environmental temperature/humidity chamber. We look forward to continuing the long-standing relationship with our valued partner, helping support their future growth in the package testing arena.”

Package performance testing is a key aspect of the product development and manufacturing process. As outlined by the International Safe Transit Association (ISTA) and as referenced in the American Society for Tests and Measurements (ASTM) procedures D4169 and D7386, simulated distribution testing is critical to successful product launches. Packages that are delivered to either the wholesale or consumer level that have been damaged in shipment can create a major financial burden to any company. Laboratory based package testing according to approved and internationally recognized quality standards enable companies to know with confidence that their product will be able to move through the distribution cycle intact and viable for use by the end user.
