SPE Vacuum Manifold
Multi-Position Solid Phase Extraction System
Athena Instruments introduces the SPE Vacuum Manifold-a precision-engineered, multi-port system designed for efficient, simultaneous solid phase extraction (SPE) of analytes from complex sample matrices. Built for pharmaceutical labs, food safety testing, environmental monitoring, and forensic analysis, this manifold enables streamlined sample preparation with reliable, contamination-free performance.
Constructed from high-quality glass or acrylic chambers with chemical-resistant components, the SPE Vacuum Manifold offers secure, consistent operation with easy visual monitoring. Available in 12 and 24-position models, it supports parallel processing to optimize laboratory workflows while maintaining strict quality standards.

Frequently Asked Questions
Q1. Why are my SPE cartridges drying unevenly during sample extraction?
Answer: Uneven drying can result from inconsistent vacuum distribution, blocked cartridges, or differences in cartridge packing. Check the connections and flow settings, and ensure cartridges are seated correctly.
Q2. How do I choose between a 12-port and a 24-port SPE vacuum manifold?
Answer : Choose based on your sample batch size, laboratory workload, and available bench space. A 12-port model may suit smaller batches, while a 24-port model can accommodate more samples simultaneously.
Q3. Can an SPE vacuum manifold be used with different sample types and solvents?
Answer: Yes, provided the manifold materials, tubing, cartridges, and collection vessels are chemically compatible with the samples and solvents. Always check compatibility and follow appropriate laboratory safety procedures.
Q4. What causes slow flow or blockage in an SPE vacuum manifold?
Answer : Slow flow may be caused by clogged cartridges, particulate matter, viscous samples, or insufficient vacuum. Check the sample preparation method, cartridge condition, tubing, and vacuum source.
Q5. How can I improve the reproducibility of solid-phase extraction results?
Answer : Keep sample volumes, cartridge conditioning, loading rates, and elution procedures consistent. Maintaining appropriate vacuum levels and inspecting the system regularly can help improve repeatability.
