Diamond (DS) and Square shaped (SQ) lightweight weighing boats provide an easy and inexpensive system for weighing any medium. They offer the following benefits: •  non contaminating (made of HIPS with hydrophobic surface) • easily fashioned to make a funnel shape • the DS model is available in either white (03) or black (09) so the operator can easily see that no trace of sample remains adhering to the boat • reproducible tare weight: batch to batch variation is normally less than 5% • Antistatic
