SAINING New Products | Serological Pipettes

Serological pipette, known in English as Serological Pipette, is a disposable plastic graduated pipe. It was used as a kind of pipette to replace the glass pipette. It is called a serological pipette because of its irreplaceable role in aseptic pipetting of serum medium. It is widely used in tissue culture, bacteriology, clinical, scientific research experiments and other fields that require aseptic operation to transfer liquids.

According to the volume, serological pipettes are mainly divided into six types: 1ml, 2ml, 5ml, 10ml, 25ml and 50ml. In addition, 100ml ultra-large-capacity serological pipettes are occasionally circulated in the market.
According to the tube type, serological pipettes are divided into stretch tubes and welded tubes. According to ASTM E934-94 standard, 1ml, 2ml, 5ml and 10ml can be used as stretching tubes, and 5ml, 10ml, 25ml and 50m can be used as welded tubes.
In addition, in the industry, in order to distinguish pipettes of different ranges, color rings/texts of different colors are sprayed on the nozzle/wrapping paper for color identification. Among them, the 1ml pipette is marked in yellow, the 2ml pipette is marked in green, the 5ml pipette is marked in blue, the 10ml pipette is marked in orange, the 25m| pipette is marked in red, and the 50m| pipette is marked in red.
Serological Pipette Features
The scale line is clear and accurate, which is convenient for identifying the volume of liquid pipet.

Two-way scale line design to meet different liquid pipetting operations.

Negative tick design for considerable extra capacity.

The tube head is filled with a filter plug to effectively avoid aerosol contamination of the sample to the pipette.

Individual paper-plastic tear-off packaging for easy access and a medical-grade sterile barrier.

Made of high-purity medical-grade polystyrene, produced in a 100,000-grade clean workshop.
