Peristaltic Dosing and Self-Priming Liquid Transfer Pump (3V / 3.7V / 5V DC) Key benefits Accurate dosing: designed for controlled liquid dispensing when precise volumes are required. Easy setup and operation: self-priming capability reduces preparation time and simplifies repeated transfers. Versatile compatibility: runs on common low-voltage DC supplies (3V, 3.7V, or 5V), making it suitable for battery-powered and bench laboratory setups. Reliable for routine tasks: suitable for repeated use in lab, ink handling, aquarium maintenance, and sampling applications. Main features Function: peristaltic pump enabling both dosing and self-priming liquid transfer. Power compatibility: supports 3V, 3.7V, and 5V DC input. Performance: provides accurate, controlled liquid delivery and efficient transfer for a range of fluids. Applications: explicitly intended for laboratory dosing and transfers, ink dispensing or circulation, aquarium dosing and maintenance, and sample collection tasks. Practical use scenarios Laboratory dosing: deliver measured reagent volumes to reaction vessels or analytical instruments with controlled, repeatable dispenses. Aquarium care: dose fertilizers, conditioners, or maintain water circulation for aquaria with timed or manual dosing routines. Ink and sampling tasks: dispense or circulate ink in small-scale systems or collect liquid samples for analysis without complex plumbing. Why choose this pump Focused on practical, repeatable performance for common low‑voltage applications. Self-priming design reduces setup steps and minimizes interruption during routine operations. Compatible with multiple DC voltages for flexible deployment in lab benches, portable setups, or hobbyist systems.
