Cartridges and Well Plates

Products

Resprep CarboPrep Plus SPE Cartridges

  • Designed specifically for the cleanup of sample extracts for organochlorine pesticides analysis.
  • Excellent alternative to Florisil products, especially for the removal of nonvolatile matrix components that contaminate GC inlets and columns.
  • Proprietary treatment renders the carbon consistent and clean, ensuring the same selectivity tube to tube, and lot to lot with no interfering background.
  • Uses the same hardware, solvents, and solvent volumes as traditional Florisil cleanup, so switching is simple.

Resprep CarboPrep SPE Cartridges

  • Improved recovery of sulfonylurea herbicides, phenols, carbamates, and triazine herbicides, compared to C18 and C8 cartridges.
  • Wide range of selectivity for both analytes and their metabolites or degradation products.
  • Rapid sampling flow rates; uncompromised recoveries.
  • Maximum capacity for contaminant cleanup.
  • Controlled manufacturing improves cleanliness and ensures reproducible performance.
  • Excellent performance removing pigments from samples.

Resprep EPH Fractionation SPE Cartridge

  • Method-specific performance for extractable petroleum hydrocarbon (EPH) analysis of soil and water samples.
  • Complete separation of aliphatic and aromatic compounds into distinct fractions.
  • Guaranteed background level under the strict reporting limits of MA and NJ EPH methods.
  • Superior lot-to-lot reproducibility and storage stability ensured by rigorous QC testing and moisture-resistant packaging.
  • Choose 5 g cartridges for higher loading capacity; use 2 g cartridges for automated systems, time-saving, and solvent reduction.

Resprep PLR SPE Products

  • Remove both proteins and phospholipids from biological samples in one easy, high-efficiency procedure.
  • Avoid signal suppression by removing interfering phospholipids from the sample matrix.
  • No method development—straightforward and effective sample preparation for acids, bases, and neutral compounds.
  • Offered in 96-well plate format for high-throughput or automated workflows and in cartridge format for lower throughput applications.
  • 3-way versatility for filtration—compatible with all common devices:
    • Vacuum manifolds
    • Positive pressure manifolds
    • Centrifugation

Resprep Polymeric SPE Cartridges and 96-Well Plates (Reversed Phase)

  • Silica-free, bonded polymeric material—no unwanted secondary silica interactions, even with basic compounds.
  • High surface area—higher loading capacity compared to silica-based sorbents.
  • Stable over a wide pH range (0–14)—won’t hydrolyze under extreme conditions.
  • Water-wettable—streamlined conditioning and equilibration steps drastically reduce solvent usage and sample prep time.
  • No flow-rate dependence—maintains retention and capacity after conditioning, even if dried out from vacuum or positive pressure flows.
  • Choose cartridges for high loading capacity; 96-well plates for high throughput and automation.
