Colony counter

DW-2 seriesColony counterIt is a digital semi-automatic bacterial testing instrument consisting of a counter, magnifying glass, dedicated probe, and counting cell. It is a generation of products designed and manufactured for the "colony counting" step in the "classical culture method" microbial experiment. Widely used for bacterial count testing in food safety, beverages, pharmaceuticals, biological products, hygiene products, drinking water, and industrial wastewater, it is the basic instrument for "colony counting" in various microbiology laboratories.

The DW-2 series is divided into DW-2 type and DW-2A type. In addition to the counting pen that comes with the host, the DW-2A type is also equipped with a movable digital semi-automatic colony counting pen that can count separately, achieving "one machine for two purposes".

Product Features:

1. Lighting method: Energy saving circular fluorescent lamp side illumination, making the comparison between bacterial colonies and culture medium clear and easy to observe.

2. Manual correction: If there are any omissions in the count, use the "manual" counting button to make up for the adjustment, and press the "reset button" to automatically reset to zero.

3. Human friendly: When counting colonies, an induction pressure counting system is used, with a "buzzer" prompt for each count, and the LED display window automatically accumulates the numbers to ensure accurate colony counting.

Technical parameters of DW-2 type

1. Light source: energy-saving circular fluorescent lamp side illumination, making the comparison between bacterial colonies and culture medium clear and easy to observe;
