We offer the widest variety of sample storage tubes on the market, and the only tubes that are 100% leak tested to ensure your samples stay secure. Depending on your sample-tracking needs, tubes are available blank or with alphanumeric identifiers. All tubes are available in 8x12 configuration, microplate footprint racks, enabling them to be filled or accessed with standard multichannel pipettes or utilized in robotic systems.
With individual sample retrieval, avoid having to thaw an entire microplate to access only a few samples and speed up sample retrieval, preventing degradation
8x12 format allows 96 tubes to be filled at once with standard liquid handlers
Tube racks have standard microplate footprint so are compatible with automated systems or microplate storage racks
Unique, specially designed racks ensure that tubes remain secure during sampling, shipping or storing
All Thermo Scientific Matrix storage tubes are available in our patented Latch Rack. This unique innovation is loaded with features that you won't find anywhere else, such as:
A lid that locks down, so it will not come off even when dropped. The lid can also be opened on hinges (to maintain sterility by not touching the lab bench) or lifted off manually or by robotics.
Open bottom and venting around each tube that promotes faster and more consistent freezing and thawing rates, as well as easy tube identification.
Solid, one-piece base that retains its shape even at low temperatures.
Orientation features that quickly identify the front of the rack, and a cutout notch that enables rack orientation in automated systems.
Stackable design that allows racks to be stacked to conserve space and not slide off each other.
For users of traditional polycarbonate racks, Matrix tubes are also
available in the Snap Rack design. The Snap Rack has an open-bottom design for reading alphanumeric or 2D barcoded tubes, and is designed to hold samples securely during low-temperature storage and shipping.
Matrix storage tubes also come packaged in environmentally sensitive refill carriers that are pre-filled with 1.4 ml storage tubes to simplify the refilling and reusing of our racks.
Tube Tracking Options
Tubes are available blank or with our patented*
alphanumeric markings designating their appropriate location within a rack. If tracking of samples on a larger scale is desired, our Matrix 2D barcoded storage tubes are etched with a globally unique 2D barcode.

Variety of Sizes
Polypropylene storage tubes are available in 0.75 ml or 1.4 ml sizes, both featuring an etched writing surface and volume graduations.
100% Leak Tested
Since your samples are the most valuable asset of your research, every tube is leak tested to ensure that cracks, holes, or other imperfections do not put your samples at risk. Currently, we are the only tube provider on the market to conduct this testing on all of its storage tubes, even those in bulk packaging.
Unique Capping Systems
To create a complete, secure sample storage system, we offer a complete line of capping systems.
