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.

Practical Tips
Assign specific colors to experimental conditions at the protocol design stage and maintain consistent color coding throughout the study.
Why: Prevents sample mix-ups and facilitates data tracking in complex multi-group experiments.
Inspect cap-to-tube seal integrity before each use, especially for tubes subjected to multiple autoclave cycles.
Why: Ensures sample security during high-speed centrifugation and prevents contamination.
Balance tubes in opposing positions within the centrifuge rotor, using water-filled tubes if necessary to achieve proper balance.
Why: Prevents rotor damage and ensures safe operation during high-speed centrifugation.
Pre-label tubes with permanent markers before sample addition to maintain traceability throughout processing.
Why: Prevents sample identity loss and maintains data integrity in analytical workflows.
Avoid filling beyond 90% capacity to prevent spillage during centrifugation and allow for sample expansion.
Why: Maintains sample integrity and prevents cross-contamination between tubes.
Verify volume accuracy using calibrated pipettes if precise volumetric measurements are critical for the protocol.
Why: Ensures accurate sample-to-reagent ratios in quantitative analytical procedures.
If caps become difficult to remove after centrifugation, allow tubes to reach room temperature before opening.
Why: Temperature equilibration relieves pressure differential that can cause caps to bind.

Background reading relevant to this product:
What is the maximum centrifugation speed these tubes can withstand?
The tubes are rated for centrifugation up to 20,000xg, suitable for most standard laboratory protocols including protein precipitation and cellular fractionation.
Can these tubes be used for long-term sample storage at ultra-low temperatures?
Polypropylene construction supports storage from -80°C to +121°C, making them suitable for freezer storage, though consult datasheet for specific freeze-thaw cycle data.
Are the tubes compatible with organic solvents commonly used in extraction protocols?
Medical-grade polypropylene provides broad chemical resistance, but compatibility with specific solvents should be verified against the chemical resistance chart in the product datasheet.
How many tubes of each color are included in the 500-tube package?
The distribution of colors in the assorted package is not specified; contact ConductScience for specific color ratios if precise counts are required for experimental design.
Can these tubes be reused after autoclaving?
While the tubes can withstand multiple autoclave cycles, reuse depends on the specific application and contamination risk; single-use is recommended for critical analytical procedures.
What is the precision of the 1.5mL volume marking?
Volume accuracy specifications are not provided; consult product datasheet for precise capacity tolerances if volumetric accuracy is critical for the application.
Are these tubes compatible with automated liquid handling systems?
Standard 1.5mL microcentrifuge tube dimensions typically fit most automated systems, but verify compatibility with specific instrument specifications before use.
