Bacteria Spreader – Sterile L-Shape & T-Shape Cell Spreaders for Precise Culture Plating

In any microbiology or cell-culture workflow, an even, reproducible spread of inoculum is the difference between reliable results and wasted plates. A bacteria spreader (also called a cell spreader) is the simple, disposable tool that makes it easy to distribute bacteria or cells uniformly across an agar plate before incubation and counting.

What Is a Bacteria Spreader?

A bacteria spreader is a pre-sterilized, ready-to-use laboratory consumable designed to spread cell or bacterial cultures evenly on a petri dish or plate. Ours is manufactured from medical-grade polypropylene (PP), pre-sterilized by EO (ethylene oxide) or Gamma irradiation, and available in both L-shape and T-shape. Because it is single-use and sterile-packed, it eliminates cross-contamination risks while delivering a smooth, streak-free surface for quantitative assays, antimicrobial susceptibility testing, and colony counting.

Product Types – L-Shape & T-Shape Spreaders

We offer a full range under the HP50000 series. Each is PP, pre-sterilized, and packed to suit different laboratory batch sizes:

L-Shape Bacteria Spreader

• HP50031 – L-shape, sterile · EO/Gamma · PP · 1 pc/pack, 2000 pcs/case

• HP50032 – L-shape, sterile · EO/Gamma · PP · 5 pcs/pack, 3000 pcs/case

• HP50033 – L-shape, sterile · EO/Gamma · PP · 10 pcs/pack, 3000 pcs/case

T-Shape Bacteria Spreader

• HP50041 – T-shape, sterile · EO/Gamma · PP · 1 pc/pack, 2000 pcs/case

• HP50042 – T-shape, sterile · EO/Gamma · PP · 5 pcs/pack, 3000 pcs/case

• HP50043 – T-shape, sterile · EO/Gamma · PP · 10 pcs/pack, 3000 pcs/case

Choose the L-shape for standard plate inoculation, or the T-shape for a firmer, more comfortable grip during high-volume plating work.

Common Use Cases

The bacteria spreader fits everyday microbiology routines: spreading bacterial suspensions for viable cell counting and colony-forming unit (CFU) determination; performing disc diffusion and antimicrobial susceptibility tests; inoculating plates for clinical diagnostics; streaking samples in food-safety and environmental monitoring labs; and evenly plating cultured cells in cell-biology experiments. Its ergonomic shape and sterile finish make it a dependable workhorse on every bench.

FAQ

1. What is a bacteria spreader used for?

It is used to spread bacterial or cell cultures evenly across the surface of a petri dish or plate, enabling uniform growth for colony counting, susceptibility testing, and other quantitative assays.

2. Which should I choose – L-shape or T-shape?

Both are sterile and equally effective. The L-shape suits standard plating, while the T-shape offers a more comfortable, stable grip for high-volume or long plating sessions. Many labs keep both in stock.

3. Are the spreaders pre-sterilized?

Yes. Every spreader is pre-sterilized by EO (ethylene oxide) or Gamma irradiation and individually or multi-packed sterile, so you can open and use it directly without additional preparation.

4. What material is the bacteria spreader made of?

It is made of medical-grade polypropylene (PP), which is lightweight, chemically resistant, and suitable for single-use sterile applications.

5. How are the spreaders packed and shipped?

Packing ranges from 1, 5, to 10 pcs per pack, with 2000–3000 pcs per case. Sterile packs protect each unit during transport, and our export team supports flexible carton quantities for bulk orders.
