OptiMATE Gradient Maker for Centrifugation

The OptiMATE Gradient Maker is an automated pre-centrifugation sample preparation instrument specifically engineered to standardize the density gradient ultracentrifugation (DGUC) workflow. The platform automates essential pre-centrifugation steps, including gradient preparation, precise dispensing, and tube sealing, minimizing manual handling and reducing user-to-user variability across operators and laboratory runs. Designed with a compact footprint, the system can operate directly within standard biosafety cabinets or bench spaces near ultracentrifugation equipment to maintain proper containment workflows.

Core Technologies & Operational Features

• Automated Gradient Preparation: Automates the formation of complex linear and step density gradients, removing the need for manual layered pipetting or gravity-driven gradient makers.

• Integrated Tube Sealing: Incorporates automated tube sealing directly into the dispense program, minimizing operator exposure to sharps or hazardous biological materials and standardizing containment for Quick-Seal configurations.

• Run Time Optimization: By generating pre-formed linear gradients prior to centrifugation, the system eliminates the extended run hours typically required for a density gradient to form under centrifugal force. This enables separation protocols to rely strictly on particle migration, cutting subsequent centrifuge separation times by over 75%.

• Protocol Standardization: Features an intuitive user interface that allows operators to easily create, specify, and publish custom methods detailing specific tube formats, reagents, and gradient volumes.

• Setup Verification: Employs a step-by-step graphical workflow guide to walk users through labware loading, accessory connection, and fluidic line placement, ensuring fast operator training and minimized setup errors.

Primary Preparative Applications

• Advanced Downstream Viral Vector Purification: Rapid preparation of precision gradients for separating full vs. empty capsids in Adeno-Associated Virus (AAV), Adenovirus (AdV), and virus-like particles (VLPs) workflows.

• Extracellular Vesicle & Exosome Isolation: Generation of continuous or step density matrices (such as Iodixanol or Sucrose) to fractionate delicate exosome subpopulations and extracellular vesicles (EVs) based on specific buoyant density.

• Density Reagent Compatibility: Automated dispensing and mixing protocols validated for major density gradient media including Sucrose, Cesium Chloride (CsCl), and Iodixanol solutions.

• Subcellular and Macromolecular Fractionation: High-reproducibility sample preparation for isolating cell organelles, ribosomes/polysomes, proteins/protein complexes, and nucleic acids/plasmids.

• Advanced Nano-Delivery Isolation: Size-distribution and density-based fractionation of lipid nanoparticles (LNPs), lipoproteins, and synthetic nanoparticles (NPs).
