Conical centrifuge tubes with real-time temperature signaling, ViewPoint™
Tubes Centrifuge Tubes
ViewPoint™ tubes are designed to help track the real-time temperature of samples when doing bench work or transferring samples to storage. ViewPoint™ centrifuge tubes visibly signal the temperature of the tube and contents, shifting to dark blue when the temperature of tube contents is below 0 °C.

ViewPoint™ tubes transition from clear to blue when exposed to cold temperatures. This multi-step and reversible thermochromic transition offers real-time temperature signaling to indicate fluctuations above and below 4 °C. At 5 °C and above ViewPoint™ tubes are clear and transparent. At 4 °C ViewPoint™ tubes transition to light blue and become slightly opaque. At 0 °C ViewPoint™ tubes reach their full progressive transition to dark blue, are completely opaque, and provide protection from Ultraviolet (UV) light.

A large number of protocols require chilled cells and/or chilled solvents. In these protocols samples and solutions are chilled for 30 minutes, 3 hours, or overnight. ViewPoint™ signals that a sample is chilled to 0 to 4 °C. Efficient chilling reduces incubation time, saving researchers time in a busy workflow. It is critical to reduce the formation of ice crystals when working with aqueous samples. Ice crystals begin to form at 0 to 4°C and damage cells. ViewPoint™ tubes begin transitioning from clear to light blue at 4 °C with full dark blue signaling at 0 °C. Real-time temperature signaling alerts the researcher to potentially harmful ice crystal formation and enables the maintenance of the desired temperature throughout experimentation.
