Malvern Creoptix WAVEdelta System with WAVEsampler Autosampler for Label-Free Binding Kinetics Analysis

The Malvern Creoptix WAVEdelta system equipped with the WAVEsampler Autosampler is an advanced label-free biosensor platform utilizing Grating-Coupled Interferometry (GCI) technology to deliver precise real-time kinetic and affinity measurements for molecular interactions. Widely adopted in biotechnology, molecular diagnostics, and biopharmaceutical research, it offers robust analysis of diverse biomolecular interactions including protein-protein, small molecule, fragment screening, and membrane protein binding.

Key technical specifications and features include:

• Noise (RMS): <0.01 pg/mm² @ 1 Hz and drift <0.3 pg/mm²/min, ensuring stable baseline for accurate data acquisition.
• Readout frequencies: selectable at 1 Hz, 10 Hz, or 40 Hz to accommodate diverse kinetic rates.
• Association constants (Ka) range: from 10² to 5×10⁷ M⁻¹s⁻¹ (small molecules) and up to 3×10⁹ M⁻¹s⁻¹ (large molecules).
• Dissociation constants (Kd) range: 10⁻⁶ to 10 s⁻¹, enabling detection of weak to tight binding affinities.
• Temperature-controlled analysis: 4°C to 45°C (up to 15°C below ambient), supporting biologically relevant assay conditions.
• No molecular weight lower limit, enabling study of small biomolecules and fragments.

The fluidics system features:

• Four parallel flow channels with flexible channel referencing and sealed disposable flow cells integrated in proprietary WAVEchips (consumables not included).
• Flow rates adjustable from 1 µL/min to 400 µL/min, compatible with crude samples and complex matrices.

Sample handling capabilities incorporate:

• Two autosampler racks each holding 48 × 1.5 mL vials, enabling high-throughput screening.
• Automated 4-buffer switching and injection volumes typically below 450 µL (100 µL typical), with sample storage options from ambient to 4–20°C.
• Sample recovery functionality to minimize waste.

Data analysis supports automated kinetic modeling and affinity determination:

• Calculation of kinetic rate constants (ka, kd, KD) through predefined kinetic models.
• Advanced analysis modes including direct kinetics, calibration-free concentration analysis (CFCA), ligand screening, and waveRAPID for rapid binding assays.

The compact benchtop design integrates robust fluidics for reliable operation with minimal maintenance, making it essential for bioprocessing, synthetic biology, and biopharmaceutical lead optimization workflows. Fully serviced and functional, this system enables precise characterization of complex biomolecular interactions critical in gene editing validation, molecular cloning, and antibody epitope mapping.

Included accessories: PC with Creoptix WAVEcontrol software v4.9.3, tubing, cables, and two 48-vial racks. WAVEchips consumables are required separately.

This system is ideal for researchers in biotechnology, molecular biology, and biomedical engineering seeking a comprehensive solution for label-free kinetic affinity analysis with automated sample processing in demanding research and biomanufacturing environments.
