ViewPoint™ tubes are a tool to help you track the real-time temperature of your samples when doing bench work or transferring samples to storage.
- Virgin Resin - Only 100% Medical Grade polypropylene resins are used in ViewPoint™ Tubes. No recycled plastics or commodity grade resins.
- Autocalvable - ViewPoint™ Centrifuge Tubes are autoclavable with a standard 122°C plasticware process for 20 minutes.
- Freezable - ViewPoint™ Centrifuge Tubes can be used for frozen storage to -80°C.
- Validated Sterile Product - All ViewPoint™ sterile tubes receive a validated irradiation dose following ISO 11137 requirements and have packaging approved for medical use.
Real-Time Temperature Signaling
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 ViewPoint™ tubes are offered in 1.5 mL, 15 mL, and 50 mL size tubes in sterile and none sterile packaging. Patents Pending.
Optimize Incubation Time on Ice
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 - 4°C. Efficient chilling reduces incubation time, saving researchers time in a busy workflow.
Real-Time Temperature Signaling Protects Samples
It is critical to reduce the formation of ice crystals when working with aqueous samples. Ice crystals begin to form at 0 – 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.
Protection from Ultraviolet Radiation
When fully dark blue (0°C) ViewPoint™ tubes provide added protection from Ultraviolet (UV) light. Unlike other tinted products, ViewPoint™ tubes become opaque at 0°C and provide protection from UV, eliminating the need for wrapping tubes in aluminum foil to shield sensitive samples from light radiation. Without a bulky aluminum foil wrap, ViewPoint™ tubes fit perfectly into racks and can be clearly labeled on the frosted writing surface.
ViewPoint™ tubes are available in our exclusive IntegraPack® 10 tube packs, reusable polypropylene racks, and non-sterile bulk bags (1.5mL) All our sterile products use medical grade packaging and are radiation sterilized following a validated ISO 11137 method.
ViewPoint™ tubes are patent pending. The three color tube labeling graphics are copyright, trademark, and trade dress of Labcon North America.
