Laboratory Plastic Pipette Production Line

Laboratory Plastic Pipette Production Line

Applications :

This production line is specifically designed to manufacture plastic pipettes, essential laboratory tools for biological research, tissue culture, and cell cultivation. Crafted from high-transparent polystyrene, these pipettes facilitate precise measurements and experiments.

Customization Options:

We offer customizable automation solutions tailored to our clients’ specifications regarding product dimensions and production volumes.

Our production line is versatile and capable of producing all seven standard sizes of pipettes circulating in the market: 1ml, 2ml, 5ml, 10ml, 25ml, 50ml, and 100ml.

Whatever your requirements, our equipment is designed to meet them, ensuring precision and efficiency in every pipette produced.

Pipette Production Line Overview

The comprehensive equipment includes extrusion molding units, ultrasonic welding devices, leak testing mechanisms, cotton plug insertion devices, silk-screen printing, and packaging units. Perfect for maintaining accuracy and quality in scientific applications. The end of the tube is marked with a color ring, and the body has a corresponding color bar background, which is convenient for quickly identifying the capacity: positive and negative double-scale design, clear printing, and improved sampling accuracy.

Tube Body Extrusion Equipment

The extrusion equipment is still a single screw and water-cooled table, haul-off, and cutting machine. The kit can be aseptically stainless steelized according to the customer’s needs for aseptic production. A wide range of customers recognizes the precision and transparency of our extrusions.


Ultrasonic welding or stretching of tube heads

Depending on the pipe size, there are two production processes: ultrasonic welding and stretching. Multiple stations are available according to production requirements. The next step is to stuff the cotton core into the tube body, customized according to the customer’s needs. Some tubes are used for blood sedimentation tests and do not require a cotton wick.

Most frequent questions and answers

Yes, indeed. You require a plastic injection machine using the injection molding process to create the nozzles necessary for pipette production. While we don’t manufacture these, we can recommend suitable options to our customers.

First and foremost, our expertise lies in extrusion equipment. The pipettes produced using our extrusion machines boast high transparency, making them ideal substitutes for glass test tubes. Additionally, our pipettes have precise volume capacities. One of our clients, who previously used an Italian brand extrusion machine, switched to our production equipment due to the superior transparency of the pipettes. Our second strength lies in our extensive experience with customized post-production equipment. Based on customer feedback, we’ve identified high-quality suppliers and actively participate in the equipment’s setup and calibration process.
