Beschreibung
Zusammenfassung:	A downhole apparatus for collecting solids fallback in the tubing of an oil producing borehole comprises two or more baskets to collect the solids fall back, each basket partially occupying a portion of the inner cross section of the tubing, leaving a portion of the inner cross section of the tubing having an unrestricted flow path. The baskets when considered in plan view along longitudinal axis of the tubing are distributed such that together they cover substantially the whole area of the tubing while leaving an unobstructed non-straight flowpath around the baskets.
