Slide-A-Lyzer® dialysis cassette is ideal for low molecular weight contaminant removal, buffer exchange, desalting and concentration. The cassette membrane is composed of low-binding regenerated cellulose and features a hermetically sealed sample chamber to maintain the highest possible sample retention. Sample introduction and removal are easily accomplished by penetrating the gasket with a hypodermic needle attached to a syringe. The gasket imparts resealability to the needle puncture, ensuring that no sample is lost from the cassette during dialysis.

Other Picture


Spectra/Por Micro-dialysis Hollow Fiber Membrane Bundle 13 kD MWCO Feature

  • Spectra/Por Micro-Dialysis Hollow Fiber Membranes
  • Ideal for micro-dialysis of critically small volumes
  • Bundled fibers for in vitro or rapid dialysis.
  • Sample volume: 140 uL
  • MWCO (Dalton): 13 kD
  • Diameter: 0.2 mm ID per fiber
  • Manufacturer number: 132274
  • Brand: Spectra/Por
  • Model: 132274
  • Part Number: AO-02911-74
  • Package Quantity: EACH
Hollow fiber membranes feature a high surface-area-to-volume ratio making them very efficient and ideal for samples smaller than 0.5 mL. Membranes are made from a biologically inert, regenerated cellulose impregnated with glycerol. Fiber bundles are ideal for the rapid and efficient dialysis of valuable small volume samples that are difficult to attain. Bundles consist of 20 fibers potted together on both ends to a pair of female Luer-Lok ports. Cap bundle with samples inside or connect to a feed pump for capillary circulation, then submerge in a standard buffer for lab dialysis or a simulated true-to-life environment for in vitro studies.
