Product overview

A closer look at
the M250.

The CarbonLinkAI M250 250 mL Large-Volume Magnetic Rack is designed for large-volume magnetic bead separation. It accommodates 250 mL reagent bottles. After the beads bind to the target material, place the vessel in the rack to collect the beads against the vessel wall, then remove the supernatant to separate the beads from the liquid. With appropriate magnetic beads and reagents, it can be used in sample separation, washing, and purification workflows.

Before selecting the rack, check the vessel outer diameter and shape to confirm compatibility. Actual separation time depends on magnetic bead properties, sample composition, and working volume.

Global magnetic rack custom expert carbonlinkai 250mL magnetic bead separation  rack rival to international standards at just 1/3 of the cost

Magnetic Bead Separation Rack Customization Expert: Carbonlinkai – An Imported Alternative with Unmatched Performance for 250mL Magnetic Bead Separation

3D Dynamic Magnetic Circuit Simulation | Multi-Gradient Circular Magnetic Pole Array | Aerospace-Grade NdFeB Magnet | International-Leading Performance & Quality at Less Than 1/3 the Price

In fields like life sciences, biopharmaceuticals, and in vitro diagnostics, the efficiency and stability of magnetic bead separation technology directly impact experimental outcomes. Traditional magnetic bead separation racks suffer from issues such as uneven magnetic fields, adsorption blind spots, and rapid magnetic decay, while the exorbitant costs of imported equipment deter many laboratories.

Carbonlinkai’s magnetic bead separation rack adheres to the core philosophy of “Imported Alternative, Beyond Substitution”, achieving a comprehensive breakthrough in performance and quality through three key technologies: 3D dynamic magnetic circuit simulation, a multi-gradient circular magnetic pole array, and aerospace-grade NdFeB magnets. It redefines the standard for magnetic bead separation—not just replacing, but exceeding expectations.

Core Technology Breakdown: International-Leading Performance Guaranteed

  1. 3D Dynamic Magnetic Circuit Simulation System – Precision Control Over Every Magnetic Fluctuation

Millions of Magnetic Field Trajectory Simulations: Utilizing AI algorithms and fluid dynamics models, the motion paths of magnetic beads in solution are simulated to optimize magnetic field distribution, ensuring efficient capture of beads in every drop of liquid.

Uniformity of 0.03T Ultra-Micro Fluctuations: Magnetic field uniformity far exceeds the industry average (typically >0.1T), eliminating local weak magnetic zones and boosting separation efficiency by over 90%.

Experimental Data Support: Third-party testing confirms Carbonlinkai’s magnetic bead recovery rate ≥99.5% with a residue rate <0.1%, rivaling top international brands.

  1. Multi-Gradient Circular Magnetic Pole Array – 40% Expanded Adsorption Range, Zero Blind Spots

Innovative Circular Magnetic Pole Design: Breaking free from the limitations of traditional bar-shaped poles, a 360° circular array layout creates a three-dimensional magnetic field coverage, expanding the adsorption range by 40%.

Zero-Blind-Spot Separation: Multi-gradient magnetic field superposition eliminates adsorption dead zones at container edges and bottoms, ensuring no beads are missed or left behind.

Expanded Application Scenarios: Compatible with 250mL conical flasks, centrifuge tubes, and other containers, meeting full-scenario demands for nucleic acid extraction, protein purification, and cell sorting.

  1. Aerospace-Grade NdFeB Magnet – <0.5% Magnetic Strength Loss Over 10 Years

Top-Tier Magnetic Material Selection: Utilizing the same neodymium iron boron (NdFeB) permanent magnets as spacecraft, with anti-corrosion surface coatings for operation in temperatures ranging from -20°C to 80°C.

Ultra-Long Lifespan Guarantee: After 10 years of accelerated aging tests, magnetic strength decay remains <0.5%, far superior to the industry average (3%-5% per year), reducing long-term usage costs.

Carbonlinkai: Crafting International Quality Through Rigorous Standards

Full-Process Quality Control System: From raw material screening to final product inspection, 12 rigorous testing procedures are implemented, including magnetic field strength testing, uniformity verification, and corrosion resistance experiments.

International Certification Endorsement: ISO 9001 quality system certification ensures quality on par with leading European and American brands.

Customer Success Stories: Serving over 50,000 laboratories worldwide, including renowned pharmaceutical companies and research institutes, with a customer repurchase rate exceeding 95%.

Three Reasons to Choose Carbonlinkai’s Magnetic Bead Separation Rack

✅ Imported Performance, Domestic Pricing: Reduces costs by 60% while outperforming similar imported products.

✅ Efficient & Stable, Saving Time and Effort: Shortens separation time by 30% with a result repeatability CV value <2%.

✅ Lifetime Maintenance, Worry-Free Service: Offers a 1-year warranty, lifetime free magnetic field calibration, and 24-hour technical support response.

“Make magnetic bead separation as steady as a clock and as strong as a foundation.”

Carbonlinkai – The Magnetic Bead Separation Rack Customization Expert, Providing Lasting Power for Precision Experiments.

Global magnetic rack custom expert carbonlinkai 250mL magnetic bead separation rack Key Technical Specifications:

Optimal Working Volume: 20mL–250mL

Recommended Centrifuge Tubes: Compatible with Shuniu 250mL reagent glass bottles or 500mL plastic wide-mouth bottles

Global magnetic rack custom expert carbonlinkai 250mL magnetic bead separation rack Operating Instructions:

1.Place the centrifuge tube containing the magnetic bead-target mixture (after binding) onto the 2.magnetic separation rack.

3.Let it stand for 1 minute until all magnetic beads are adsorbed onto the tube wall.

4.Carefully pour out or aspirate the liquid using a pipette.

Remove the reagent bottle from the magnetic separation rack and place it back on the benchtop to complete the magnetic separation process.
