Microbiological Environmental Monitoring Products
Colony Counter
An illuminated digital counting station with magnification and tactile tally control for accurate enumeration of microbial colonies on agar plates.
- Illuminated Counting Grid
- Adjustable Magnifier
- Digital Tally Display
- Pressure or Probe Counting
Product Introduction
The Colony Counter combines an illuminated gridded plate stage, adjustable magnification and an electronic tally in one compact bench instrument. The operator marks or touches each visible colony while the counter advances with audible feedback. Interchangeable plate adapters, contrast control and a stable arm help maintain viewing comfort across common Petri dish formats.
Key Features
An adjustable magnifier enlarges small or closely spaced colonies without moving the plate.
Tactile or probe activation provides immediate count feedback and reduces missed entries.
A gridded stage supports systematic scanning of crowded plates.
Customer Product Concerns
Manual enumeration must minimize skipped colonies, double counts and operator fatigue while accommodating varied plate contrast.
Small colonies are difficult to distinguish from agar texture.Magnification and adjustable transmitted illumination improve visual separation.
Dense plates cause the operator to lose position.The segmented grid supports an orderly section-by-section counting pattern.
Repeated manual tallying interrupts visual concentration.Pressure-sensitive or handheld probe input records each selection directly.
Different dish diameters sit off-center on the stage.Interchangeable centering adapters locate common Petri dish formats.
Typical Applications
Environmental monitoring colony enumerationWater and food microbiologyQuality-control plate countingResearch culture assessment
