The Thermo Scientific 7701 Repipet Jr. is a fixed-volume 1 mL bottle-top dispenser designed for quick, repetitive liquid handling in laboratory settings. It is a practical choice for workflows where the same volume needs to be dispensed repeatedly without the complexity of an adjustable dispenser.

Built with a rugged polypropylene body to help reduce breakage, this manual dispenser is suited for routine bench use and straightforward operation. A single press dispenses a fixed 1 mL volume, helping improve consistency and speed in repetitive transfer work.

Based on the current product information, the unit is supplied with an amber glass container, a plastic container, four interchangeable cap adapters for 20-400, 22-400, 24-400, and 28-400 screw caps, plus an extra 12 in. (30.5 cm) PTFE resin intake tube. The listing also states that 1.0 to 3.0 mL sizes come with 8 oz. (240 mL) containers.

This model is described as suitable for dispensing a variety of chemicals, but it is not recommended for oils, hydrocarbons, petroleum-based chemicals, oxidizing acids, concentrated acids, alicyclics, or solvents. That warning should stay clearly visible on the page.
