FAQ

1,What is cell counter?

Cell counter is an instrument used to quickly and accurately count the number of cells in a biological sample. It plays an important role in life science research, medical diagnosis, drug development and other fields. Through automation and digitization, it greatly improves the efficiency and accuracy of cell counting, reduces human error and saves time and labor costs compared with manual counting.

2,What is the different between the cell counter results and manual counting?

Many steps in manual operation can lead to deviations, as manual counting heavily depends on the operator's skill level. For example, sample collection may not ensure consistent cell numbers each time, and adding the sample can result in uneven distribution. Our cell counter uses intelligent and advanced image recognition algorithm, simple operation and accurate data, which can effectively improve the work efficiency.

3,Are you manufacturer?

Yes, All the device and software of our products are fully self-researched and self-produced.

4,Can you introduce about “Newtonoptic”?

Our company was established in 2018, we are the innovative enterprise focusing on the application of intelligent imaging technology in the life science field, with a focus on cell analysis. Now our company has established a complete R&D, production, and sales system.

5,What are the main application of your products?

Scientific research, cell culture, drug screening and vaccine production.

6,What parameter does your cell counter mainly detect?

Our cell counter mainly detect the cell concentration, viability, diameters, cluster, growth curve and roundness.

7,What consumable do you use for your cell counter?

All of our devices use our six-well disposable counting slide, and each company's counting slide is not universal.

8,Does your cell counter have a fluorescent mode?

Our products have bright-field and fluorescence models, according to customer needs to choose different device models.

9,What is the recommended cell concentration detection range for your cell counter?

The detectable range for parameters is 1×10⁴ to 3×10⁷ cells/ml. The optimal detection range we recommend is 5×10⁵ to 5×10⁶ cells/ml.

10,Do parameters need to be preset for each different type of cell?

No, for cells with larger diameters or more conventional cell shapes, parameters can be saved after automatic focusing and named 'Conventional Cells' for direct use. For smaller diameter cells, after automatic focusing, the cell threshold needs to be manually adjusted (typically, the live cell threshold is 220-240, and the dead cell threshold is 230-250), then the parameters can be saved. In future experiments, if cells with similar morphology and diameter are encountered, the preset parameters can be directly applied.

11,What is the difference between the GPC200 and GPC100 models?

The thickness of the GPC200 is 200μm, with a sample volume of 25μl, while the thickness of the GPC100 is 100μm, with a sample volume of 15μl. We recommend using the GPC200 for routine cell types, as it allows for a larger sample volume, resulting in more cells in the image and higher accuracy. For high-concentration or small diameter cells, the GPC100 is recommended, as it ensures sufficient cell capture while effectively preventing cell layering.

12,What are growth curves and roundness?

The growth curve is created by plotting the cell concentration results of different batches (other indicators can also be selected). For example, in drug screening experiments, the curve can be used to assess the effect of the drug on cell concentration/viability.

Cell roundness is a parameter of the cell's outline. The more the cell shape approaches a perfect circle, the roundness value gets closer to 1. Conversely, if the cell shape is more irregular, the roundness value approaches 0.

13,Does your equipment require regular maintenance?

Before the delivery, our equipment undergoes various tests to ensure normal operation. Under normal circumstances, we conduct an annual follow-up to check the equipment's condition and, if needed, perform software upgrades. We will maintain good communication with you.

14,Can you do the OEM?

Yes, we can customize the appearance, packaging, nameplate and the software of the device, the MOQ is more than 10 sets when OEM.

​​​​​​​15,What is your MOQ?

1 PCS for regular model.

16,What should I do if the device has a technical problem?

Our company has a professional production and technical team, will ensure the normal use of the device before delivery, when the device problems we will have a professional after-sales team to provide technical support.

17,What is your warranty?

Our standard warranty period for the equipment is one year. If an extended warranty is needed, an additional 5% of the equipment price will be added each year.

18,What is your delivery time?

About 25~30 days after you confirm the order.

19,What delivery term do you do?

We usually do EXW terms, or we can also arrange delivery to your forwarder, but there is an additional cost of freight.

20,What payment terms do you do?

100% TT payment or cash before delivery.
