These solvent dispensers are made from ESD-safe polyethylene. They have no stopper or cap to remove and the solvent is easily released when needed. Stainless steel valves seal the contents in the bottle until use, preventing spills, dripping and escaping fumes. Fluid pumped into the dish does not drip back into the bottle, keeping stored liquids uncontaminated. Bottles are available in 120ml or 180ml.
