SP Industries, the leaders in freeze drying technology, has introduced the VirTis 96 Well Freeze Drying Systems for high throughput applications. These new and unique systems include either glass or plastic vials set in an aluminum vial holder with an exclusive LyoCap(TM) 96 Well Capmat Lyophilization Stopper.

The solid aluminum 96 well vial holders provide efficient and even heat distribution to ensure fast and consistent freeze drying results for every sample. Glass vials in the aluminum rack further speed the freeze drying process with better heat transfer. The fluted LyoCap 96 Well Capmat Stoppers enable samples to be quickly freeze dried and then sealed under vacuum or inert gas after the lyophilization cycle is complete.

The unique combination of the VirTis 96 Well Freeze Drying Systems' components eliminate the problems caused by the edge effect when freeze drying in standard 96 well plastic plates. Samples in the wells around the edges of plastic plates tend to dry faster than samples in the middle wells which retain more water to the point that they can collapse when freeze drying is terminated.

The new VirTis 96 Well Freeze Drying Systems now provide scientists an alternative to storing sensitive or heat labile samples at low temperatures. "Until now, freeze drying small samples in 96 well plates was unreliable or unpredictable," said Joe Costello, Marketing Manager, VirTis Brand Products. "These new systems now provide the reliability and controls for freeze drying those types of samples."
