Colony Counter for Microbiology Labs - 0.1 mm Resolution & Auto-Tally
A Colony Counter is widely used in microbiology laboratories for counting bacterial and microbial colonies grown on agar plates. Accurate colony counting supports microbial analysis in pharmaceutical laboratories, food testing facilities, clinical laboratories, biotechnology centers, and environmental monitoring units.
Modern Digital Colony Counter systems support organized colony analysis with features such as illuminated viewing areas, magnification support, digital displays, and auto-tally functions. Laboratories processing multiple Petri dishes during daily microbiology procedures often use an Automatic Colony Counter to improve workflow efficiency and counting consistency.
A Bacterial Colony Counter with 0.1 mm resolution supports visibility of small colonies and helps improve microbial observation during laboratory analysis.
Understanding Colony Counter Equipment
A Laboratory Colony Counter is designed to count visible microbial colonies formed on agar media after incubation procedures. Colonies may originate from bacteria, fungi, yeast, or other microorganisms present in the sample.
A typical Digital Colony Counter may include:
Illuminated counting surface
Electronic counting display
Pressure-sensitive counting probe
Many Automated Colony Counter systems also include optical imaging support for colony identification and microbial analysis.
The Colony Counter principle is based on visual identification and numerical recording of microbial colonies present on culture plates.
The Petri dish is placed on the illuminated platform, allowing colonies to become more visible through magnification and contrast lighting. The operator touches colonies using a counting pen or probe, and the system automatically records the count on the display panel.
An Automated Bacterial Colony Counter may also use digital imaging systems to identify colonies according to shape, size, and contrast differences.
The 0.1 mm resolution capability supports the detection of smaller microbial colonies during microbiology procedures.
Importance of 0.1 mm Resolution in Colony Counting
High-resolution visibility is important during microbial analysis, where small colonies require careful differentiation.
A Microbial Colony Counter with 0.1 mm resolution supports:
Improved visibility of tiny colonies
Better separation of closely positioned colonies
Organized colony counting procedures
Enhanced microbial observation
Improved plate reading clarity
Reduced visual strain during prolonged laboratory operation
Microbiology laboratories handling pharmaceutical products, water samples, food products, and bacterial cultures often benefit from enhanced optical clarity.
Auto-Tally Function in Automatic Colony Counter Equipment
The auto-tally feature allows colony counts to register electronically during analysis. When the operator touches a colony using the probe, the system automatically records the count on the digital display.
This function supports organized laboratory documentation and simplifies microbial plate analysis.
Advantages of Auto-Tally Systems
Electronic count registration supports efficient microbiology workflows.
Digital displays provide continuous count visibility during operation.
Reduced Manual Documentation
Automatic recording minimizes repeated handwritten count tracking.
Organized Laboratory Workflow
Auto-tally functions support structured microbiological analysis procedures.
Suitable for High Sample Volume
Large laboratories processing multiple agar plates benefit from faster counting procedures.
