3.8ml Tri-coded Tube, 48-format, External Thread

• Next Generation manufacturing techniques
• Made from high-quality virgin PP
• Permanently laser etched 2D code on base, 1D linear barcode and human readable number on the side, ensuring a permanent link between sample and data
• 2D codes readable without removing tubes from racks
• High contrast 2D codes are more reliably readable in frost or condensation conditions
• 100% quality control, each tube is tested to ensure both readability and uniqueness
• Leak tested to ensure sample security
• External thread tubes provide greater working volume than internal thread tubes
• Suitable for sealing with screw caps
• Suitable for cryogenic storage*

*Not for use in liquid phase nitrogen

Screw caps

• A deforming compression seal more effective than a silicone alternative
• A non-silicone seal means the cap can never be over-tightened
• Caps and tubes are manufactured from the same material, preventing differential expansion during freeze-thaw cycles
• A double-start thread engages in a maximum rotation of 180°, thereby facilitating automation

48 format SBS racks

• TwistLock: prevents tubes rotating within the rack to enable automated capping and de-capping of screw caps; provided as standard with the option available to remove
• TubeLock: prevents tubes from falling out, even in lidless racks; useful in manual workflows; activate by applying pressure on the tube top, clicking it into place; tubes can be ordered pre-locked or non-locked
• LidLock: enables racks to withstand a 1m drop test for added sample security
• Automatic rack orientation: a unique 2D code rack identifier readable at the same time as the tube 2D code; for automatic rack orientation and secure sample tracking
• Direct laser etching: a cutout window on the rack sides allow the linear barcode to be read more easily; linear barcodes can be laser etched directly onto racks
