Vacuum manifolds for SPE sample preparation, filtration, and elusion are available in 12,24,48 and 96 port configurations. These manifolds permit consistent extraction and filtration results. Ria Via Multiple sample processing with these manifolds simplifies procedures and saves time. disposal, and clean-up. The manifolds consist of a clear glass chamber and lid to which a vacuum is applied to draw a sample through an SPE column, cartridge, or disk. Adjustable racks placed in the glass vacuum chamber will accommodate a variety of sample collection vessels, including test tubes, autosampler vials, volumetric flasks, and Erlenmeyer flasks. Eluants are deposited directly into the collection vessel of choice via polypropylene, optional stainless steel, or Teflon needles. Drying attachments for the 12 and 24 port manifolds will direct a flow of air or nitrogen into the collection vessels to dry eluants prior to further analysis. Drying attachments can also be connected, via adapters, to SPE columns or cartridges in order to dry the column or cartridge prior to final elusion. Optional disposable solvent resistant polypropylene liners are available for the twelve port manifolds. These waste liners greatly simplify sample preparation, solvent disposal, and clean-up.
CAUTION: Do not operate this manifold without first reading and fully understanding the operating instructions

Waste Receiver Container
Solvent resistant polypropylene container for the 12 & 24-Positions manifold.
These waste containers greatly simplify sample preparation, solvent disposal and clean-up. Depending on the nature of the solvent used, the waste container can be reused many times prior to discarding.
Replacement parts
Manifolds come complete with all necessary gauges and accessories. Individual replacement parts may be sold separately..
Large Volume Samplers (optional part)
Allows for easy “In-Line” transfer of large volumes of low viscosity liquid samples directly from any sample container to SPE tubes. The Large volume samplers consist of 1/8” PTFE tubing and a screw-fitted SPE tube adapter. Vacuum pressure delivered from the vacuum manifold is used to pull the sample through the PTFE tubing into the SPE tube.

Mainfold Needles
Teflon needles & disposable, fit many different manifold types, and eliminate cross contamination by extending into the collection tube. They also provide a complete Teflon fluid path for samples to virtually eliminate extractables. Available plain or with a valve. Stainless Steel and Polypropylene needles are also available 1(Standard) ,2 ( Disposable )
Vacuum Trap
fully self-contained vacuum trap. Made from durable Borosilicate Glass , the trap can be emptied and reused. For safety, the lid includes an automatic overflow shutoff valve, which will prevent cross contamination of the vacuum pump or wall outlet. Vacuum Pump and our line of aspiration manifolds to improve laboratory safety and efficiency. Available 1 ltr ,2 ltr & 5ltr .
Oil Free Vacuum Pump 45-s
SPE Manifold vacuum port to connect a standard laboratory vacuum pump. Vacuum pulls the sample through the stationary phase, metered by the stopcocks, to control the speed of the extraction process and the sample flow. Waste and wash solvents are discarded and analytes are collected in sample tubes below the manifold completing the extraction.

HPLC Column Cartridge
Solid Phase Extraction is a fast and efficient sample preparation technique for cleanup or concentration for analysis, HPLC, GC, TLC, UV, IR and an excellent tool for method development that is used by most chromatographers today.
SPE is a form of digital (step-wise) chromatography designed to extract, partition, and / or adsorb one or more components from a liquid phase (sample) onto a stationary phase (adsorbent or resin). An adsorbed substance can be removed from the adsorbent by step-wise increase of elution strength of the eluent (step gradient technique). SPE extends a chromatographic system’s lifetime, improves qualitative and quantitative analysis, and the demand placed on an analytical instrument is considerably lessened.
In general, SPE is used for three important purposes in state-of-the-art analyses:
• Concentration of the analyte (up to factor 10.000 – increase of chromatographic sensibility / improved limits of detection)
• Removal of interfering compounds (protection of subsequent analyses like HPLC, GC, TLC, UV or IR spectroscopy,…)
• Changing an analyte’s environment to a simpler matrix more suitable for subsequent analyses.
Advantages of SPE compared to classical liquid-liquid extraction:
• Lower consumption of solvents
• Faster – enormous time savings
• Lower costs per sample
• Potential for automation
• High consistency in individual sample handling
• More specific selectivity because of the broad range of adsorbents and different retention mechanisms
• Optimisation of extraction by variation or adjusting of the solid phase and chromatographic conditions
