The tube slides back to reveal a collecting cavity behind the tip.Once at the required depth the sleeve is slid back, allowing the cavity to fill with sample. The sleeve is closed and the probe withdrawn. Manufactured in 316 stainless steel in standard nominal lengths of 600 mm, 1000 mm & 1500 mm.
A disposable polypropylene version is also available.
