Ensuring sample integrity during high-speed separation requires durable, high-purity vessels designed for significant centrifugal forces. LabFriend provides a comprehensive selection of centrifuge tubes, located within the separating & centrifuging section of our distillation, separation, and filtration department. These professional-grade tubes are engineered for leak-proof performance and chemical resistance in molecular biology, clinical, and research applications.
Why Choose Professional Centrifuge Tubes?
Our curated collection of centrifuging consumables is designed for mechanical strength, clarity, and certified purity across several material types:
- High-Purity Microtubes: We stock LLG Microtubes and Eppendorf Tubes® (0.5 ml to 5.0 ml) made from premium polypropylene. These are certified DNase, RNase, and pyrogen-free for sensitive molecular work.
- Graduated Conical Tubes: Utilize LLG Centrifuge Tubes and Corning 15 ml and 50 ml vessels, featuring clear graduations and large writing areas for easy sample tracking.
- High-Speed & Chemical Resistance: Explore Thermo Scientific Nalgene tubes, manufactured from copolymers like PPCO or PC for superior mechanical strength and resistance to aggressive reagents.
- Precision Glassware: For applications requiring maximum chemical inertness, we offer DWK Duran and Karl Hecht borosilicate 3.3 glass centrifuge tubes, available in both conical and round-bottom shapes.
- Specialized Clinical Formats: Find BRAND and Kartell tubes in various materials including PMP and soda-lime glass, ideal for specialized clinical and industrial separations.
LabFriend supplies centrifuge tubes from the most diverse and trusted global brands:
- LLG Labware: Cost-effective, high-quality microtubes and conical tubes for daily laboratory tasks.
- BRAND: German-engineered Plastibrand vessels known for high-precision manufacturing and durability.
- Thermo Scientific: Features the Nalgene range of high-performance plastic tubes for demanding RCF applications.
- Corning: Industry-standard conical tubes favored for cell culture and general liquid handling.
- DWK Life Sciences: The premier choice for Duran borosilicate glass tubes for solvent-heavy workflows.
- Greiner Bio-One: High-performance tubes optimized for biotechnology and clinical research.
The right vessel is critical for successful separation; to complete your centrifuging or analytical workflow, we recommend exploring these related categories:
- Benchtop Centrifuges: Pair your tubes with high-speed Eppendorf or Corning systems for efficient pelleting.
- Syringe Filters: Clarify supernatants using LLG Spheros or Sartorius Minisart units after centrifugation.
- Membrane Filters: Perform absolute microfiltration on centrifuged samples using Sartorius discs.
- Microfilter Plates: For high-throughput processing, explore AHN Biotechnologie 96-well filter plates.
Unsure if you need the high-speed rating of Nalgene PPCO or the chemical inertness of Duran glass? Our team provides local technical support to help you find the perfect analytical solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. When should I use glass centrifuge tubes instead of plastic?
Glass tubes from brands like DWK Duran or Karl Hecht should be used when working with aggressive solvents that can degrade plastic, or when high-temperature resistance is required.
2. What is the difference between PP and PC tubes?
Polypropylene (PP) offers excellent chemical resistance and is autoclavable, while Polycarbonate (PC) provides superior clarity and can withstand higher centrifugal forces (RCF), though it has lower chemical resistance.
3. What are "self-standing" centrifuge tubes?
Self-standing tubes, often available from BRAND or Kartell, feature a skirted base that allows them to stand upright on a bench without a rack, which is convenient for reagent preparation.
4. How do I know if a tube is DNase/RNase-free?
Tubes intended for molecular biology, such as those from LLG Labware and Eppendorf, are specifically certified and labeled as such to ensure they do not contaminate sensitive DNA/RNA samples.
