1.5 mL Conical Microcentrifuge Tubes with Tethered Cap — PPC, Yellow, 250/Bag
These 1.5 mL conical microcentrifuge tubes feature a permanently attached tethered cap, molded graduation markings, and yellow polypropylene copolymer (PPC) construction — supplied non-sterile in 250/Bag for high-throughput molecular biology, clinical, and research workflows. Polypropylene copolymer delivers enhanced flexibility and impact resistance compared to standard PP homopolymer, reducing the risk of cracking during high-speed centrifuge runs. Lot-to-lot dimensional consistency ensures reliable seating in standard 1.5 mL microcentrifuge rotor positions.

Frequently Asked Questions
Are these microcentrifuge tubes sterile?
No — the 214-3410-Y80 tubes are supplied non-sterile in sealed 250/Bag packaging. For applications requiring sterility, pre-sterilization by the end user or selection of a sterile-certified product is recommended.
What is the advantage of a tethered cap versus a separate snap cap?
The permanently attached hinge eliminates cap loss during high-throughput pipetting and reduces cross-contamination risk. Single-handed opening and closing also improves throughput in repetitive microvolume workflows.
Why choose polypropylene copolymer (PPC) over standard polypropylene homopolymer?
PPC offers greater flexibility and impact resistance than standard PP homopolymer, which lowers the risk of tube cracking or hinge fatigue during high-speed microcentrifuge runs and in cold-temperature storage conditions.
Will these tubes fit standard microcentrifuge rotors?
Yes — the 1.5 mL conical format is dimensionally consistent with standard microcentrifuge rotor positions. Lot-to-lot manufacturing controls maintain uniform geometry and wall thickness across every bag.
