ABSTRACT:
A container having a longitudinal passage is provided with a filter for collecting thereon cellular components having a particle size range of 5 microns or greater. Where the cellular components are to be harvested from a hostile environment such as voided urine specimen, the hostile environment is discharged, after passing through the filter, from the container through one end thereof to separate the cells from the hostile environment as soon as possible. The cellular components harvested on the filter are washed with a suitable media such as a saline solution and a nutrient preservative media, or fixative, such as by way of example formaldehyde is added to the container to assist in stabilizing the harvested cellular components on the filter. Where the cellular components are harvested from a hostile environment, a suitable closure may be added to one end of the container to close off the longitudinal passage before the preserving media is added. A closure is provided to seal off the collected cellular components in the container before transport.
