Repeater Pipette (Stepper Pipette) for Repetitive Dispensing
Description
Product Overview
The Hawach Repeater Pipette is a manual positive displacement pipette designed for repetitive dispensing of liquids from 10 μL to 5 mL. By aspirating liquid once and dispensing multiple equal aliquots without refilling, it significantly improves workflow efficiency and reduces operator fatigue during repetitive laboratory procedures.
Compatible with disposable dispenser tips ranging from 0.5 mL to 50 mL, the pipette supports up to 48 dispensing cycles from a single aspiration. It is suitable for aqueous, viscous, volatile, and foaming liquids, making it ideal for clinical diagnostics, molecular biology, pharmaceutical research, chemical analysis, food testing, and industrial quality control laboratories.
Its lightweight ergonomic design, secure tip locking mechanism, and reliable positive displacement principle ensure accurate and reproducible dispensing performance even when handling challenging liquid types.

Why Choose the Hawach Repeater Pipette
Eliminates Refilling Between Steps
Aspirate once and dispense up to 48 times – significantly reducing handling time and improving workflow efficiency.
Reduces Repetitive Strain
Lightweight design and smooth operation minimize hand fatigue during long dispensing series, protecting operator health.
Minimizes Errors
By reducing the number of fill/dispense sequences, the repeater pipette lowers the risk of volume errors and improves consistency across samples.
Cost-Effective Alternative
When multichannel pipettes are outside of budget, repeater pipettes offer a cost-effective method to increase repetitive dispensing efficiency.
Versatile Liquid Handling
Suitable for a wide range of liquids – including viscous, volatile, and foaming samples – when used with appropriate dispenser tips.
Reduced Consumable Waste
One disposable tip can be used for many dispensing steps, reducing plastic waste compared to changing tips for each individual transfer.

Frequently Asked Questions
What is a repeater pipette used for?
A repeater pipette is used to dispense the same liquid volume multiple times from a single aspiration. It is commonly used for microplate filling, reagent aliquoting, serial dispensing, and high-throughput laboratory workflows.
What is the difference between a repeater pipette and a standard micropipette?
A standard micropipette requires a new aspiration before every dispense. A repeater pipette allows multiple dispensing cycles after one aspiration, significantly increasing efficiency for repetitive liquid handling tasks.
Can this repeater pipette handle viscous or volatile liquids?
Yes. The positive displacement operating principle enables accurate dispensing of viscous, volatile, foaming, and high-density liquids when used with compatible dispenser tips.
How many dispensing cycles can be performed from one aspiration?
Depending on the selected dial setting and dispenser tip size, up to 48 dispensing cycles can be performed from a single aspiration.
What dispenser tip sizes are available?
Compatible dispenser tips are available in capacities of 0.5 mL, 1.25 mL, 2.5 mL, 5 mL, 12.5 mL, 25 mL, and 50 mL.
