Cell Spreader

Cell spreader is used to spread cells or bacteria evenly in cell culture process, usually on a culture plate, or a petri dish.

Cell spreader for sale: L shape, T shape, triangle shape. Individual and bulk package.

MOQ: 1 CARTON.

Feature of Cell Spreader

Made of pure medical grade HIPS material, good toughness.
Smooth surface, no burrs, uniform friction.

Produced in a 100,000-level clean workshop, no DNA/RNA enzymes, no pyrogens, no endotoxins.
Independent paper production, standardized packaging and batch non-standardized packaging are optional
L-shaped/T-shaped/triangular shaped are optional.

Step of Using Cell Spreader

1. Sterilization: If reusable, lab spreader is sterilized, usually by dipping it in ethanol and flaming or autoclaving.

2. Sample Application: A small volume of the liquid sample is pipetted onto the center of the agar plate.

3. Spreading: The cell spreader is used to gently and evenly spread the liquid across the plate in a circular motion, ensuring cells or bacteria are distributed evenly.

Different Use of 3 Shapes of Lab Spreader

•l shaped cell spreader : Best for small plates, bacterial colony counting, and precise, small-volume spreading. Commonly used for spreading bacterial cultures uniformly across plates, especially when preparing samples for colony counting or CFU (colony-forming unit) assays.

•T-shaped cell spreader : Ideal for large or square plates, uniform lawns, and higher sample volumes. Ideal for creating uniform bacterial lawns for antibiotic sensitivity testing or other assays requiring a consistent cell layer.

•Triangle cell spreader: Used for precise, small-area spreading and selective plating techniques. Useful in techniques where precise streaking patterns are needed, such as for creating bacterial growth gradients or spreading smaller volumes in specific patterns.

FAQ of Cell Spreader

What is the purpose of using bacteria spreader?

•Uniform Colony Growth
Ensures even distribution of cells for consistent colony formation, essential in bacterial culture quantification.
•Improved Accuracy
Allows for reproducible spreading across plates, leading to more reliable experimental results.
•Reduced Cross-Contamination
Disposable spreaders or sterile techniques with reusable spreaders help prevent cross-contamination between samples.

What is the difference between a disposable cell spreader and an inoculating loop?

Spreading sticks are used to spread liquid samples on the entire surface of a culture dish; while inoculating loops are often used to separate colonies by streaking or picking single colonies.

Can spreading sticks be reused?

Polypropylene is disposable; glass or stainless steel can be sterilized repeatedly at high temperatures.

Will the operation of the bacti cell spreader affect the distribution of colonies?

If the operation is too aggressive or the sterilization is not thorough, it may cause overlapping or contamination of colonies. It is recommended to use a disposable spreading stick sterilized by gamma rays to ensure experimental reliability.
