S*PURE
Solid Phase Extraction
S*PURE has been making Davisil® silica for over a quarter century. It is the foundation for all our silica-based SPE products, including Alltech®, Vydac®, and GracePure™ brands. Having complete control over the entire media process ensures highly consistent performance, and uninterrupted supply.
Experts in Media Production
Using a consistent and pure silica base, and employing tightly controlled bonding techniques, insures predictable analyte-sorbent interactions. Both of these aspects also play equal importance in manufacturing a bonded phase with high and reproducible recoveries.

Format: SPE Column
Sizes: 1.5, 4 and 8 mL
 |
Format: SPE Columns
Sizes: 1 and 3 mL
Summary: Our HLB & Mixed Mode Polymeric SPE are water wettable and not affected by drying out. They offer high
surface area and pH stability for reproducible recoveries for a wide range of analyses. We use extractable free medical grade polypropylene tubes, our devices are subjected to over 20 performance criteria and guaranteed to have less than 2% bed weight variation. |
|
Format: SPE Columns
Sizes: 1.5, 4, 8, 15, 25, 75mL (the entire tube volume) Summary: In production for over 25 years, with proven consistency, this is our most comprehensive SPE product line. It includes 30 media types in over 10 different bed weights. And with a complete offering of reversed, normal, and specialty medias exhibiting unique retention properties, you are sure to find the packing that delivers a cleaner, more concentrated sample. |

Format: SPE Columns
Sizes: 4, 8mL (the entire tube volume) Summary: Choose this ultra-low extractable version for very sensitive applications. Nine selected media are packed into highly inert fluorinated polypropylene tubes with PTFE frits. Less expensive than glass extraction devices, this durable format offers comparable inertness without the added concern of being easily broken. |
| Maxi-Clean™ Cartridges
Sizes: 300, 600, 900mg (media amount, not device volume)
Summary: The Maxi-Clean™ line is offered in many of the same media as the Extract-Clean™ line, but slightly paired down, with over 20 chemistries available. This lure hub cartridge device is not as prevalent in the SPE industry, and while manual processing is most common, this format offers a number of other interesting processing options, including multimedia extractions. |

Format: SPE Columns
Sizes: 1, 3, 6, 12, 20, 60mL (volume above the packing) Summary: Our in-house capability to make everything from the silica particle to the finished good means we can deliver GracePure™ as the best value in SPE. With a concise offering of 11 sorbents in six bed weights, this high-quality SPE product line is a result of operational excellence that S*Pure is known for. |
Vydac® ColumnsFormat: SPE ColumnsSizes: 1, 3mL (volume above the packing) Summary: Ideal for extraction, concentration and cleanup of biological samples. This 300Å silica-based media has the same properties as the industry-leading Vydac® TP HPLC packing. Offered in C18 and C4, use for a variety of protein and peptide applications. |
