Medical-grade polypropylene microcentrifuge tubes designed for routine sample processing and storage in research laboratories. These 1.5mL tubes feature color-coded caps in five distinct colors (blue, green, red, yellow, purple) to facilitate sample organization and prevent cross-contamination during multi-sample protocols. The tubes are manufactured from virgin polypropylene to ensure chemical resistance and sample integrity.

Autoclavable construction withstands repeated sterilization cycles at 121°C, while the robust design supports centrifugation forces up to 20,000xg without deformation or failure. The precision-molded cap design provides secure sealing to prevent sample evaporation and contamination during storage and processing. Color coding enables systematic sample tracking in complex experimental workflows involving multiple treatment groups or time points.

How It Works

Microcentrifuge tubes function as sample containers engineered to withstand the mechanical stresses of high-speed centrifugation while maintaining sample integrity. The polypropylene construction provides chemical inertness across a wide pH range and temperature spectrum, preventing leaching of compounds that could interfere with analytical measurements. The conical bottom design facilitates complete sample recovery and efficient pellet formation during centrifugal separation procedures.

Color-coded caps serve as a visual identification system that reduces the risk of sample mix-ups in multi-group experiments. Each color can be assigned to specific treatment conditions, time points, or sample types, creating an immediate visual reference during processing. The secure cap-to-tube interface prevents sample loss during high-speed centrifugation through a precision-molded seal that maintains integrity even under mechanical stress.

Autoclave compatibility enables sterilization of tubes prior to use in sterile applications, eliminating potential microbial contamination that could compromise experimental results. The thermal stability of polypropylene allows repeated sterilization cycles without degradation of mechanical properties or dimensional accuracy.
