In flow cytometry, accuracy is everything. From research labs to clinical applications, scientists and technicians rely on precise cell sorting and analysis to generate valid, reproducible results. Fluorescence-Activated Cell Sorting (FACS) depends on optimal sample handling and preparation, and at the heart of that process are FACS tubes, small components that make a big difference in the quality of your data.
At Stellar Scientific, our high-performance FACS tubes are engineered for high performance, consistent quality, and compatibility with major flow cytometers. If you're working in immunology, cancer research, cell biology, or any discipline that requires flow cytometry, it’s important to understand why the right FACS tubes are critical and what makes ours stand out.
What Are FACS Tubes?
FACS tubes are specialized containers designed to hold and deliver cell samples into a flow cytometer. They must meet strict standards for size, material quality, optical clarity, and cap compatibility. Most flow cytometers are calibrated to accept 12 × 75 mm tubes, a standard we follow to ensure seamless integration into your workflows.
These tubes help maintain the integrity of cell samples, reduce contamination risks, and prevent sample loss or interference during analysis. Poor-quality tubes can cause clogs, inaccurate readings, or wasted samples, issues that can slow research progress and increase operational costs.
Key Features of Our High-Performance FACS Tubes
Precision Manufacturing for Reliable Performance
Our FACS tube is manufactured with rigorous quality control to ensure consistent wall thickness, precise dimensions, and smooth surfaces. This precision supports stable fluid dynamics during flow cytometry, minimizing variables that could impact your results.
High Optical Clarity
Made from high-grade virgin polystyrene, our tubes provide excellent light transmission. This clarity allows for accurate laser excitation and fluorescence detection with minimal distortion, improving signal-to-noise ratio and overall data accuracy.
Secure, Leak-Proof Caps
Each tube includes a tight-fitting cap to prevent sample loss and contamination. We offer both domed and flat-cap styles to match different protocols and preferences.
Sterile and Non-Pyrogenic Options
For sensitive or regulated applications, we offer sterile, non-pyrogenic versions. All sterilized tubes are clearly labeled and lot-traceable for quality assurance.
Compatibility with Automated Systems
Our polystyrene FACS tubes are compatible with popular robotic sample handlers and carousel loaders, reducing manual handling, minimizing errors, and improving throughput for high-volume laboratories.
Resistant to Cell Adherence
A specially treated surface helps prevent cells from sticking to the tube walls, ensuring maximum recovery and accurate analysis.
Packaging Options and Accessories
We offer multiple packaging formats to meet different workflow needs, including:
- 5 mL polystyrene tubes with caps (sterile, in re-sealable bags of 25)
- Tubes without caps (sealed bags of 125 or cardboard trays of 250)
- Separate plain two-position caps and blue 35 μm mesh strainer caps
Applications Across Scientific Fields
Immunology
In immunophenotyping and T-cell analysis, maintaining sample purity and viability is critical. Our sterile, high-clarity tubes help ensure accurate identification of even rare immune cell populations.
Oncology Research
Cancer research often involves small, fragile cell populations. Our low-adherence surfaces protect these cells during preparation and sorting, supporting more reliable results.
Stem Cell and Regenerative Medicine
Stem cells are highly sensitive to environmental changes and mechanical stress. Our precision-molded tubes support gentle handling, preserving viability for downstream applications.
Clinical Diagnostics
In clinical workflows for hematologic malignancies, immune deficiencies, and infectious diseases, our tubes support rapid, reliable processing where data integrity is essential.
How to Achieve Optimal Results with FACS Tubes
- Use fresh tubes for each run to reduce the risk of contamination or degradation.
- Match the cap style to your centrifugation or storage needs.
- Label with solvent-resistant markers for long-lasting identification.
- Store tubes in a clean, dry environment away from heat and UV exposure.
High-quality lab FACS tubes are more than just containers; they are essential for producing precise, reproducible, and actionable data.
