SPE Manifolds & Systems
Solid Phase Extraction (SPE) manifolds and systems are designed to facilitate the simultaneous processing of multiple samples, improving throughput and consistency in analytical workflows. They provide controlled conditions for sample loading, washing, and elution, ensuring reproducible extraction and clean-up of analytes prior to chromatographic or mass spectrometric analysis. Designed for laboratory reliability, these systems support a wide range of sorbent chemistries and formats, making them suitable for environmental, pharmaceutical, food, and clinical testing applications.
VACUUM MANIFOLDS
Vacuum manifolds use vacuum pressure to draw liquid samples through SPE cartridges or plates at the same time across multiple positions. This method speeds up extractions and increases throughput while remaining simple to operate. Vacuum systems are widely used in laboratories where efficiency is important and provide a reliable way to handle routine sample preparation.
GRAVITY FLOW MANIFOLDS
Gravity flow manifolds allow liquid samples to pass through SPE cartridges or columns under the influence of gravity alone. This simple approach requires minimal equipment and is easy to set up, making it a practical option for straightforward extractions. Although slower than other methods, gravity flow provides steady processing that can be sufficient for less time-sensitive applications.
POSITIVE PRESSURE MANIFOLDS
Positive pressure manifolds use controlled gas pressure to push samples evenly through SPE cartridges or plates. By applying pressure from above, they support uniform processing across all positions, which can improve the reliability of results. This makes them particularly useful when preparing complex or particle-rich samples, where even flow is important for reproducible results.
AUTOMATED SPE SYSTEMS
Automated SPE systems integrate robotic handling with programmable control of sample preparation steps, enabling high-throughput, unattended operation. These platforms reduce manual intervention, enhance reproducibility, and minimise human error in large-scale or routine analyses. Automated systems are ideal for laboratories processing large batches of samples where consistency and efficiency are critical.
