United Scientific Supplies, UNSLT002-2D-PC-PK10, 2d Tubes, Push Caps 1 mLFeatures:Virgin PP materials, heavy metal ions, hazardous materials are at the highest level of safetyInternal thread provides the optimal sealing for storage at ultralow temperaturesEnhanced internal spiral design with silicone seals for a secure seal for air travelThe 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 frictionProduced 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 Push Cap, 2D Barcode 96-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. 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. 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. Working volume: The 1.0 ml tubes with internal thread can be sealed with TPE caps 96-format. The working volume is larger than 0.98 ml (different working volume for different temperatures or caps).
