1. Apparatus for testing formations surrounding an earth borehole, comprising:
- a tool movable through the borehole, said tool having a flow line running therethrough;
means, in said tool, for establishing fluid communication between the formations and the flow line in said tool; and
a predetermined plurality of sample bottles operatively connected to the flow line, at least one of the plurality of sample bottles being replaced with a sand trap for separating sand from the fluid from the formations traveling in said flow line whereby a sample of sand is collected.
