Description of manufacturer

On-chip Biotechnologies Co.,Ltd. is a life science analysis equipment development company, and the first in the world to use microfluid chips in order to develop the Flow Cytometer and the Cell Sorter.

In both devices, fluids are contained in a disposable microfluidic chip that does not requirea sheath or waste tank and is maintenance-free. Both devices are compact enough to fit inside a biosafety cabinet. Furthermore, with the cell sorter, the company brought to fruition the technology to sort cells without inflicted damage.

Product description

What is the Flow Cytometer and the Cell Sorter?
The Flow Cytometer measures the light scattered when a laser beam is sent through particles such as cells in a liquid flowing at a high speed and for fluorescence emitted by particles labeled beforehand with fluorescent substances. A cell sorter is a type of Flow Cytometer that can sort particular cells. Both devices are essential in cytology.

Technology description of On-chip Biotechnologies Co.,Ltd.

Micro flow path technology

Sterile and contamination-free due to disposable chips

Disposable and interchangeable microfluidic chips are used for cell analysis and sorting in both On-chip Flow and On-chip Sort.

The acrylic chips have a flow path width of 80μm and depth of 50~80μm, formed on a base plate of 5.5 cm x 4.0 cm. All of fluids and reservoirs are placed in these interchangeable microfluidic chips, so there is no contamination among samples as well as no contamination to the equipment.

Neither device requires a sheath tank and both are compact enough to fit inside a regular sized biosafety cabinet.

Chips for cell analysis and sorting are available in sterilized or non- sterilized form.

On-chip Biotechnologies theory of cell sorting

On-chip Biotechnologies has developed its own technology (flow shift method) for controlling cell flow on microfluidic chips.

In On-chip Sort, cells flow on microfluidic paths via pneumatic control. Identification of an object cell is made, in the same way as for the previous cell sorters, by identifying scattered light or fluorescence emitted by a laser beam irradiated on the cells.

On the other hand, for the flow shift method sorting mechanism is completely different from the method in the conventional equipment. According to this new method, at the instant the object cell crosses the microfluidic path, air pushes and pulls the fluid to force target cells into the sorting reservoir while letting non-target cells flow down and be collected into a waste reservoir.

Sorting cells without damaging them

Damage-free cell sorting has been achieved with microfluidic chips.

With On-chip Sort, the company adopted its original Flow shift method in order to achieve sorting with incredibly minute pressure without the use of ultrasonic sound waves or electrical charges. This technology allowe for cells easily susceptible to damage such as nerve cells to be sorted.

As shown in the following pictures, nerve cell B that had been sorted with a traditional sorter was killed by damage while non-sorted nerve cell A and nerve cell C that had been sorted with On-chip Sort showed a characteristic unique to nerve cell by extending its axon.


Flow cytometer On-chip Flow

The Flow Cytometer is easy to operate and maintenance-free and biohazard-free. Due to that the microfluidic chips are disposable, all fluids are replaceable for every measurement taken.

The company’s Flow Cytometer has the following advantages:

Easy to operate

It is easy to operate and does not require proficiency. You can use the Flow Cytometer in the same manner you would use a spectrophotometer. All you have to do is to prepare a sample and sheath fluid, and set them on the equipment.

Ideal for analyzing biohazardous samples

All fluids retained in the microfluidic chips and the chips are disposable. Therefore, you can analyze, even biohazardous samples such as pathogenic bacteria and virus-infected cell without worrying about fluidic contamination.

Compact enough to be fit inside a biosafety cabinet

Because the equipment is compact, you can install it within a biosafety cabinet. You can take measures easily against dispersal of samples and for the operators' safety.

It works with microscale samples

It can analyze microscale samples from 10μlµ. It is ideal for analyzing your precious samples.


Because the company’s microfluidic chips are disposable, there is no need to clean instrument and maintenance is easy.

Cell sorter "On-chip Sort"

The world’s first microfluidic chip method that provides safe, high-precision sorting.

Our cell sorter based on microfluidic chips has the following advantages:

Sterile cell sorting

All fluids are contained in disposable sterile microfluidic chips. Because the chips are disposable, there is no contamination between samples and no aerosols are generated.

Cell sorting can be done in culture fluid

You can sort cells not only in the sheath solution, but also in the sample buffer solution and culture fluid.

It can correspond to a microscale sample

You can sort microscale samples from 10~. Ideal for your precious samples!

Compact and maintenance-free

It is compact and can be installed in a biosafety cabinet. Because its microfluidic chips are disposable, there is no need for clean-up and maintenance is easy.
