CellMicroSieves

       scanning electron micrograph of CellMicroSieves

   CellMicroSieves  allows the rapid, yet gentle, isolation of cells, organelles, or cellular debris.  Unlike traditional filters, CellMicroSieves is a precision woven matrix of pure nylon filaments that is available with pores ranging from 5  to 200 microns.  CellMicroSieves does not  wet  and contains no dyes, detergents or extractables.  Extremely low protein affinity means that cells and proteins will not bind to CellMicroSieves.  They have a wide variety of distinctive uses a specific sized porous screens in the laboratory:

• Rapid collection of tissue culture cells without centrifugation.

• Isolation of specific cell types from a dissociated tissue sample, allowing only a single type of cell to pass through.

• Separation of different sized cells from a mixture of cell types.

• Concentration and isolation of cells from a bioreactor.

• Barrier to separate cells or tissues, while allowing free media diffusion.

• Prefilter to prevent clogging of final filter.

   CellMicroSieves are versatile tools in the laboratory. A pure nylon product that is biologically inert.  Autoclavable and can be repeatedly washed and reused. CellMicroSieves are resistant to most acidic or basic conditions and many solvents.

ORDERING INFORMATION

SIEVE HOLDERS : Polypropylene 2 piece frame with adjustable metal tightener. Securely holds the CellMicroSieves taut or used to form a funnel.  Autoclavable.

Type A (on left) and Type B (on right)

    Type A:   Borosilicate glass filtration apparatus with stainless steel filter support. An aluminum clamp sandwiches a CellMicroSieves 47mm circle between the 300 ml top funnel and base.  Autoclavable.

    Type B:  Polysulfone non-toxic plastic filtration unit  that can be repeatedly re-used and autoclaved. Uses a 47mm CellMicroSieves circle.  Funnel and base both have a 300 ml capacity.
