Manual SPE and Sample Cleanup Accessories

W-SPE is a manual manifold for the extraction and enrichment of organic compounds. It accepts standard-size solid-phase extraction cartridges and gives each position its own valve, so flow through individual cartridges can be controlled during conditioning, loading and elution. It is available in 12- or 24-position versions and is intended for routine, low-volume cleanup work.

• Manual manifold for organic extraction and enrichment
• Accepts standard-size solid-phase extraction cartridges
• Independent valve at each position, imported from the United States
• 12- or 24-position configuration to match batch size
• Simple operation and durable construction for daily use

IFAD removes water from an organic extract without adding a drying agent. Under vacuum, the sample is drawn across a PTFE membrane; the hydrophobic membrane passes organic solvent while the aqueous phase is retained in the filter cup. It replaces anhydrous sodium sulfate in the drying step, which removes the drying-agent weighing step from the workflow.

• PTFE membrane exploits hydrophobicity to separate solvent from water
• Vacuum draws the sample across the separation membrane
• Organic solvent passes through; the aqueous phase stays in the filter cup
• Replaces anhydrous sodium sulfate as the drying step
• Keeps drying agent out of the extract and out of the analysis

ET is a nitrogen blowdown concentrator for parallel sample concentration. Nitrogen flow is combined with heating, and the metal bath avoids the condensation problems that a water bath creates, so several extracts can be brought down in one batch. It is a straightforward bench instrument for the solvent-reduction step that follows extraction and precedes injection.

• Nitrogen blowdown combined with heating for rapid concentration
• Metal bath heating avoids water-vapor condensation
• Parallel concentration of several samples in one batch
• Quick, simple operation for routine solvent reduction
• Concentrates extracts ahead of GC and LC analysis

Extrapid combines cartridge and disk solid-phase extraction on a single manual instrument. It covers small-volume work with 1, 3 and 6 mL cartridges and larger volumes with 47 mm and 90 mm extraction disks, and each channel has a fine-adjust valve for flow control. The internal contact materials are all PEEK, which keeps the system suitable for trace-level and PFAS analysis while remaining an economical alternative.

• Column and disk extraction on one instrument
• Takes 1, 3 and 6 mL cartridges plus 47 mm and 90 mm disks
• Per-channel flow fine-adjust valves for controlled, reproducible extraction
• All-PEEK internal contact materials for ultra-low background
• Economic choice that covers small and large sample volumes

RWAI monitors the liquid level in a waste container and sounds an alarm when it passes the set limit. It is fitted to chromatographs and sample preparation instruments that discharge organic waste, where the container is often out of sight below the bench. The alarm turns an unmonitored overflow into a prompt to empty the vessel.

• Sensor detects the waste-liquid level in the container
• Alarms automatically once the level passes the limit
• Suits chromatographs and preparation instruments that discharge organic waste
• Addresses containers that are difficult to inspect during a run
