The AELAB StepMate Stepper is a positive-displacement, continuously adjustable dispenser designed for repetitive liquid handling. With dispensing volumes from 10 µL to 5 mL and up to 48 consecutive dispensing steps, it ensures accuracy, durability, and ease of use in clinical, research, food, and chemical laboratories.
The AELAB StepMate Stepper is a lightweight, robust, and ergonomic repetitive dispenser designed for laboratories requiring precision in liquid handling. With dispensing volumes from 10 µL to 5 mL, compatibility with tips up to 50 mL, and up to 48 steps in succession, it is the perfect solution for efficient and accurate repetitive pipetting.
The AELAB StepMate Stepper operates on a positive-displacement piston system. After selecting the desired dispensing volume via the dial, the user attaches a polypropylene dispenser tip. With each plunger movement, a precise aliquot is dispensed. The device supports up to 48 consecutive dispensing steps, significantly improving workflow efficiency in repetitive tasks.
