Globe Scientific 0.5mL Sterile Screw Cap Microtube Overview
The Globe Scientific 0.5mL Sterile Screw Cap Microtube (SKU 111690) is engineered for secure sample containment in molecular, clinical, and research workflows. Built from polypropylene, this tube pairs an attached screw cap with an integrated O-ring to support a tight, leak-resistant seal during storage and transport.
Sterility ships standard, so you can move directly to sample prep without an autoclave step. The attached cap stays with the tube to reduce loss and cross-contamination, while the color-insert-ready cap design helps technicians sort and label samples at a glance.
Packaged 500 per bag with 2 bags per unit, this configuration suits high-throughput labs that need reliable consumables at volume. Each case delivers 1000 tubes ready for archiving, aliquoting, and routine bench work.

Laboratory Applications
These microtubes hold small-volume samples for PCR setup, DNA and RNA storage, enzyme aliquoting, and reagent prep. The O-ring seal helps guard against evaporation and leakage during freezing, making the tube a fit for biobanking and long-term sample archiving.
Clinical and research technicians use color-insert caps to organize samples by batch, patient, or assay. Sterile packaging supports cell culture, microbiology, and sensitive molecular protocols where contamination control is critical.
