Core Barrel (Double Tube & Triple Tube)
ROSCHEN Core Barrel is a precision instrument designed to maximise core recovery in site investigation and exploratory drilling programmes. With this core barrel is its possilble to obtain as near to 100% volumetric ocre recovery in as undisturbed condition as it is possilbe to achieve with rotary core drilling equipment. It is not uncommon for drillers to report 98% + core recovery in the most difficult formations.
