1.5 mL Polypropylene Microcentrifuge Tubes, No Cap, Graduated, Natural — 1000/Pack
The Globe Scientific 1.5 mL Microcentrifuge Tube is a graduated, capless polypropylene microtube designed for high-throughput sample prep, automated liquid handling, and routine aliquoting. Natural translucency aids visual volume checks, while the no-cap format streamlines workflows where separate caps or automated sealing are preferred.

Frequently Asked Questions
Are these microcentrifuge tubes sterile?
No. SKU 111642 is supplied non-sterile in bulk packs of 1000, making it suitable for general aliquoting, storage, and prep applications that do not require certified sterility.
Do these tubes come with caps?
No. This is a capless format, ideal for workflows using separate caps, sealing films, or automated sealers. Capless design also reduces handling steps on high-throughput platforms.
What is the maximum recommended centrifugation speed?
Polypropylene microtubes of this size are typically rated for routine microcentrifuge speeds. Confirm the manufacturer's RCF rating for your protocol, especially when running near maximum g-force.
Are graduation marks printed on the tube?
Yes. The tubes are graduated to support quick visual volume estimation, and the natural translucent polypropylene improves readability of sample levels and meniscus position.
