Labcon ViewPoint™ thermochromic tubes offer real-time temperature signaling to indicate temperature excursions above and below 0-4° C.

PETALUMA, CA, September 30, 2019 /24-7PressRelease/ — Labcon North America (, the world’s leading manufacturer of Earth Friendly® laboratory disposables, announced today that it is launching a revolutionary line of thermochromic centrifuge tubes for laboratories called ViewPoint™.

This new Patent Pending line of tubes transition from clear to blue when exposed to near-freezing temperatures. This reversible thermochromic transition allows researchers to maintain the desired sample temperature throughout experimentation.

At temperatures above 4°C the tubes are clear and transparent. At 4°C they reversibly transition to light blue and become slightly opaque. At 0°C and below ViewPoint™ tubes reach their full progressive transition to dark blue, are completely opaque, and provide added protection from Ultraviolet (UV) light.

“ViewPoint™ tubes can help labs avoid unknowns by making temperature excursions easily observable in real-time,” said Bo Heinz, M.Sc., Labcon Product Manager.

ViewPoint™ tubes are available in 1.5mL, 15mL, and 50mL sizes in a variety of sustainable packaging options, including Labcon’s exclusive IntegraPack®.
