A squeezer based on designs developed by P. A. Kriukov has been constructed, using fabricated and commercially available parts, and used with a standard laboratory press to recover interstitial water from sediments. Analyzable amounts of water were extracted from as little as 2 g of relatively compact sediment at pressures of 3,000 to 9,000 psi (approximately 200 to 600 kg/cm (super 2) ). Extraction of water from most samples of core materials from Recent to Paleocene sediments was completed in three minutes. The residue after squeezing is in the form of a compact pellet which may be further dried to determine total water content of the original sample. The present work confirms Soviet experience, with similar squeezers, that pressure does not appreciably affect the composition of extracted waters when proper precautions are observed.
