Hangzhou Qiwei Instrument Co., Ltd. is one of the leading manufacturers and suppliers of Colony Counter in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk Colony Counter in stock here from our factory. We also accept customized orders.
This digital display colony counter is a semi‑automatic device designed for routine bacterial colony enumeration in microbiology laboratories. Equipped with a digital readout, probe pen and backlit counting platform, it helps lab technicians record colony quantities while inspecting petri dishes.
The XK97-A has a counting range of 0 to 999, which makes it possible to count colonies separately by touching them with the probe pen. The three-digit screen displays the accumulated number as a result of each appropriate counting action that the device has registered. To support colony observation, its round bright side illumination and darker counting chamber provide visual contrast.
The XK97-A is suitable for regular microbiological testing in educational or research laboratories, as well as pharmaceutical quality control, natural product testing, and environmental monitoring.
The XK97-A offers a practical solution for laboratories that lacks the extra voice-reporting capabilities of the XK98-A model. It is simple to use and has probe-assisted operation.
product key technologies
Model XK97-A colony counter is a semi-automatic device designed for bacterial counting, fitted with a digital readout system. The whole unit consists of three core parts: main counter unit, test probe and dedicated counting chamber. Adopting mature CMOS circuit technology, this device features a dark-toned counting chamber equipped with ring-shaped fluorescent side lamps. The lighting delivers sharp visual contrast, making bacterial colonies easy to identify.
Designed in line with industry counting norms, it comes with a 3-digit display. When the colony number on a single Petri dish exceeds 300, users need to dilute the sample and run the test again to guarantee precise counting results.
Usage Method
Carry out regular operations following the guidance below. For practical testing work, you must refer to the official user manual together with your lab's microbiology test protocols.
Step 1: Instrument setup
Set the XK97-A on a flat, stable lab bench. Plug in the power cord and power the unit up. The built-in light for the counting platform will activate, and the screen should read "000".
Step 2: Attach the probe and clear the reading
Plug the probe pen into its matching socket. Hit the Reset key to zero the counter ahead of counting a new agar plate.
Step 3: Load the Petri dish
Put your ready Petri dish onto the counting platform. Fine-tune its placement so colonies can be seen clearly under the built-in lighting.
Step 4: Perform counting with the probe pen
Lightly tap every visible colony using the probe pen. Check that the instrument captures the count and the screen value rises accordingly. Take care not to tap the same colony multiple times.
Step 5: Double-check the count
Once you finish scanning the plate, recheck the dish to spot any colonies you may have skipped or counted twice. Turn on the magnification feature if you need a closer look.
Step 6: Log data and reset the device
Save the final result in line with your lab's data recording rules. Take the Petri dish away, then press Reset before you begin counting the next sample.
Important operating reminder: If colonies grow too densely to count single colonies accurately, follow your lab's dilution protocol and retest the sample. The 0–999 counting range of this device does not mean all plates can be counted directly without dilution.

FAQ
1. What placement rules should be followed for the XK97-A colony counter?
Set the unit on a level, sturdy lab workbench to stop it from falling over. Do not place it under direct sunlight, and keep it clear of moisture, strong vibration as well as acidic and alkaline corrosive fumes.
2. How to protect the device from dust and contamination after use?
Once you finish using it, cut off the power, detach the probe and fit the dust cover in place.
3. What maintenance work is needed for the counting chamber?
Take care not to let live bacteria or cultures pollute the bottom of the counting chamber. Should any liquid spill or dirt appear, wipe the area gently right away.
4. What should users do when colonies are overly dense or the quantity is excessively high?
Heavy colony growth or overlapping colonies will make accurate single-colony counting difficult. Users need to implement the lab's validated dilution method and run the test again, instead of simply counting up to the instrument's maximum reading.
5. What distinguishes the XK97-A from the XK98-A?
These two semi-automatic colony counters share the same 0–999 counting range. The XK97-A works with digital readout and probe-assisted counting only. The XK98-A retains these functions and comes with extra voice prompt / audio alert capability. You may choose the suitable model based on your lab's working habits.
