Space Saving, Cost Saving
Thread is on the outside of the tube so there is no loss in working volume
when a cap is added.
Excellent Seal Performance
No silicone seal is used, the cap cannot be overtightened.
External thread screw cap tubes use a deforming compression seal which
provides a more effective seal than a silicone alternative.
The cap and tube are manufactured from the same polypropylene
homopolymer (resin) to prevent differential expansion during freeze-thaw
NB. Homopolymer provides a lower binding and wider temperature tolerance than
FluidX External Thread Caps feature a double start thread. The thread is engaged in a maximum rotation of 180° (rather than 360° for internal thread) which makes the cap easier to use, especially in automated environments.
Using a compression seal rather than an “O” ring results in a tighter seal with a more consistent torque.
Ideal for Cold Storage
As with all FluidX cryo tubes, these tubes can be flash frozen and stored at temperatures as low as -196°C .
FluidX cryo tubes can be stored within the Gas Phase of Liquid Nitrogen. In line with other manufactures we do not recommend that FluidX tubes are submerged in liquid Nitrogen.
Superior Barcode Quality
2D barcode is directly laser etched to tube. Easy to read, even in harsh conditions or when damaged.
Black on white 2D Datamatrix barcode with improved white quiet zone, FluidX offer one of the few storage tube ranges that adheres fully to the ECC200 standard.
Barcode generated using latest and most sophisticated error correction methods.
100% QC. Every tube checked to ensure they meet our exacting standards for readability.
All FluidX cryo tubes are compatible with our whole rack 2D barcode readers and single tube 2D barcode readers, which are able to read any 2D barcoded tube that conforms to EEC200 standard.
Excellent Rack Performance
All FluidX 96 well format racks are constructed for enhanced durability.
SBS format, low profile rack design to maximise available freezer space.
Locking lid for added sample security.
Open bottom for scanning tube 2D barcodes on whole rack readers.
All FluidX racks come with a linear barcode is directly laser etched to side, avoids complications caused by label displacement during repeated freeze thaw cycles or mechanical use.
The latest FluidX racks also feature a unique 2D rack ID which provides rack identification when using any FluidX whole rack 2D barcode readers without the need for an additional linear barcode reader. Rack and tube 2D barcode reading is performed simultaneously, ensuring a continuous chain of custody.
Free from DNase, RNase, DNA and endotoxins.
Sterilisation is achieved by irradiation conducted in accordance with EN552, ISO11137 and SI/AAMI/ST31/ST32 standards.

Linear barcode on rack side
• External thread screw top tubes provide greater working volume, and require less freezer space, than internal thread alternatives.
• Polypropylene tube ideal for cryogenic storage in gas phase liquid nitrogen.
