The Labshark cell spreader (also referred to as a plate spreader, bacteria spreader, or colony spreader) is a precision instrument designed for bacterial spreading, inoculation, isolation, and identification in microbiology laboratories. Available in electric and manual models, this microbiology spreader offers flexible operation to suit different experimental needs.
The electric model utilizes non-contact infrared sensor technology for simple, hands-free start/stop operation. It features adjustable rotation time (0–160 s, 6 settings) and speed (25–150 rpm, 6 settings), ensuring uniform spreading across the entire Petri dish. The turntable is equipped with a built-in non-slip rubber lining to secure the dish during operation. Compatible with plastic and glass Petri dishes from 60 mm to 150 mm, this lab spreader is ideal for high-throughput, reproducible spreading experiments.

The electric plate spreader features non-contact infrared sensor technology for simple, hands-free operation. Simply wave your hand over the sensor to start or stop the rotation, reducing the risk of contamination and improving workflow efficiency.
The cell spreader offers 6 adjustable timer settings from 0 to 160 seconds, or a continuous operation mode. This flexibility allows you to tailor the spreading process to different sample types and experimental protocols.
With 6 adjustable speed settings ranging from 25 to 150 rpm, this bacteria spreader ensures uniform spreading of bacterial cultures across the entire Petri dish. The consistent rotation speed improves reproducibility and colony separation.
The turntable of this colony spreader features a built-in non-slip rubber lining that securely holds the Petri dish in place during rotation. This prevents the dish from slipping or moving, ensuring safe and accurate operation.
The electric microbiology spreader is compatible with both plastic and glass Petri dishes ranging from 60 mm to 150 mm in diameter. The manual model supports dishes from 90 mm to 140 mm. This wide compatibility makes it suitable for a full range of Petri dish sizes.
Both models feature a dual workstation design. The electric model includes one removable workstation, allowing for flexible placement and easy cleaning. This inoculation spreader is ideal for processing multiple samples in sequence.
Your Need | Recommended Model |
|---|---|
High-throughput, reproducible spreading | Electric Plate Spreader – Infrared sensor, 6 speed/timer settings, 1.2 kg. |
Teaching demonstrations, small-batch experiments | Manual Plate Spreader – Manual control, 2 fixed workstations, 2.4 kg. |
Place the cell spreader on a stable, flat work surface.
Ensure the turntable and non-slip rubber lining are clean.
Plug in the electric model and power on.
Place the Petri dish (60–150 mm) onto the turntable, ensuring it is centered and secured by the non-slip lining.
For the electric model, select the desired speed and timer settings.
For the electric model: Wave your hand over the infrared sensor to start rotation. The dish will rotate automatically.
For the manual model: Rotate the turntable by hand at a steady speed.
Spread the sample evenly using a sterile spreader or loop.
After spreading, stop the rotation (wave hand over sensor or stop manually).
Remove the Petri dish carefully.
Clean the turntable and rubber lining with a mild detergent. Do not immerse the electric model in water.
Precautions:
Do not touch the rotating turntable during operation.
Ensure the Petri dish is properly secured before starting.
Do not use excessive force when placing or removing dishes.
Clean the instrument after each use to prevent contamination.
Our cell spreader is widely used in:
Bacterial Inoculation: Even spreading of bacterial cultures on agar plates.
Microbial Isolation: Separation of individual colonies for identification.
Microbial Identification: Preparation of pure cultures for biochemical tests.
Teaching Demonstrations: Educational laboratories for microbiology courses.
High-Throughput Screening: Reproducible spreading for large-scale experiments.
A: The electric plate spreader uses an infrared sensor for hands-free start/stop, with adjustable speed (25–150 rpm) and timer (0–160 s). The manual plate spreader requires manual rotation and has a fixed speed.
A: The electric model is compatible with 60–150 mm dishes. The manual model supports 90–140 mm dishes.
A: Yes, both models are compatible with plastic and glass Petri dishes.
A: Wipe the turntable and non-slip lining with a mild detergent. Do not immerse the electric model in water.
A: No, the electric model requires a power cord (1.5 m). The manual model requires no power.
Whether you are a microbiologist, lab technician, or educator, Labshark cell spreaders offer the perfect combination of precision, flexibility, and ease of use. Choose between the electric and manual models to match your specific application needs.
