Cell Spreader (Sterile L-Shaped) for Microbiology & Cell Culture

Sterile Plate Spreader for Uniform Agar Distribution

A sterile cell spreader is a laboratory tool used to evenly distribute bacterial or cell suspensions across agar plates in microbiology and cell culture applications. Uniform spreading is essential for consistent colony formation, accurate colony counting, and reproducible experimental results.

Hawach cell spreaders are designed with a smooth L-shaped head to provide controlled, even spreading without damaging agar surfaces, supporting reliable performance in routine laboratory workflows and high-throughput environments.

Designed for Accurate Plate Spreading in Microbiology

Cell spreaders are widely used for agar plate spreading, microbial culture preparation, and transformation plating. A consistent spreading process reduces variability between samples and improves the reliability of downstream analysis.

FAQ

What is a cell spreader used for?

A cell spreader is used to evenly distribute bacterial or cell suspensions on agar plates to ensure uniform growth and accurate colony analysis.

Are sterile cell spreaders necessary?

Yes. Sterile cell spreaders help prevent contamination and are recommended for microbiology and cell culture applications.

What size cell spreader should I choose?

An 18 mm spreader is commonly used and fits standard 90 mm and 100 mm Petri dishes.

Are cell spreaders disposable?

Yes. Most sterile cell spreaders are designed for single use to avoid cross-contamination and maintain experimental accuracy.
