Product Description

Self-standing polypropylene screw cap micro tubes with O-ring seal and color-coded caps for versatile laboratory sample organization. Available in 0.5, 1.5, and 2.0 mL with seven cap color options — clear, red, blue, purple, yellow, green, and amber. The self-standing flat base allows rack-free bench use during filling, labeling, and processing workflows.

The O-ring sealed screw cap provides a reliable leak-proof closure across the full temperature range from ultra-low freezer storage to water bath and heat block incubation. The conical interior ensures efficient sample recovery and complete collection after centrifugation. Amber tubes provide UV and light protection for photosensitive samples.

Storage & Handling
  • Store in original packaging in a clean, dry environment away from direct sunlight and UV exposure
  • Handle with powder-free gloves to prevent contamination of tube surfaces
  • Ensure screw cap is fully and evenly tightened before centrifugation, freezer storage, or water bath use
  • Verify O-ring is correctly seated before closing cap in leak-critical applications
  • Leave adequate headspace when filling for freezer storage to accommodate sample expansion during freezing
  • Use amber tubes for photosensitive samples — protect from UV and visible light during storage and handling
  • Dispose of used tubes per your institution's biosafety and waste disposal guidelines
Frequently Asked Questions
What is the advantage of the O-ring seal?
The O-ring creates a secondary compression seal between the cap and tube — providing leak-proof performance across temperature extremes including ultra-low freezer storage, water bath incubation, and heat block use. This is particularly important for applications involving repeated temperature cycling where standard caps may allow micro-leakage.
How do I use color-coded caps effectively?
Assign a unique cap color to each experimental condition, time point, sample group, or patient to enable instant visual identification without reading labels during rapid workflows. With seven colors available across three volumes, you can maintain consistent color-coding across 0.5, 1.5, and 2.0 mL tubes within the same experiment.
When should I use amber tubes?
Use amber tubes for samples or reagents that are sensitive to UV or visible light — including fluorescent dyes, light-sensitive enzymes, photoreactive compounds, and certain biological samples. The amber tube body and cap together block UV and much of the visible spectrum to protect sample integrity during storage and handling.
