United Scientific Supplies, UNSLT001-2D-IT-PK10, 2d Tubes, Screw Caps, 1 mLFeatures:Comes PreassembledVirgin PP materials, heavy metal ions, hazardous materials are at the highest level of safetyInternal thread provides the optimal sealing for storage at ultra-low temperaturesEnhanced internal spiral design with silicone seals for a secure seal for air travelProduced in ISO Level 8 (Class 100, 000-cleanroom) and automated production line to ensure DNase/RNase and Pyrogen free1.0 ml Internal Thread Tube with TPE Screw Cap, 2D Barcode96-well Rack: This rack features a laser etched 1D rack barcode on one side and "Twist-Lock" to prevent tubes from turning during screw (de)capping. The one-piece process allows the code to be integrated into the tube body, firm and non-shedding, resistant to acid and alkali and orga-nic solvents and mechanical friction. Original coding and digital co-distribution technology and pure black and white ultra-high contrast Data-Matrix code ensure the reliability of code reading. Twist lock function prevents the pipe body from falling and rotating in the box, which is convenient for automatic equipment to cover and cover automatically. Original coding and digital co-distribution technology and pure black and white ultra-high contrast Data-Matrix code ensure the reliability of code reading.Code options: The 1.0 ml tubes are with a unique 2D Data-Matrix code. Due to the In-mold labeling technique used to manufacture the sample storage tubes, the white code surface cannot be separated from the transparent tube.Physical PropertiesRaw materials Medical Grade Polypropylene (PP)Non-polluting Sterile, DNAase, RNAase, Endotoxin FreeTransportation safety In accordance with IATA requirementsTwo-dimensional barcode Customizable, up to 14 x 14 data rectangle, ECC200 built-in error correctionVisual code double guarantee There is a human readable code on the side of the 2D codeApplicable temperature range -196 deg C (liquid nitrogen) to 121 deg C (steam sterilization)Product certification EU CE Certification (IVDD Directive)Production quality system ISO13485:2016 Medical Device Quality Management.
