These pipettes are made of a bio-compatible material, and are resistant against most solvents and cleaning agents, as well as acids and lyes. Consequently, they are a high-quality and practical alternative to plastic pipettes. For more than 30 years, Hilgenberg has been manufacturing Pasteur pipettes on their own production sites in Germany, and ever since, customers have valued their extremely high quality. This long experience enables us to supply high-grade products that leave nothing to be desired, e.g. when working in a laboratory. Apart from our standard range of Pasteur pipettes, we also supply individual solutions that are precisely matched to your requirements.
For applications requiring gamma sterilization, we supply special soda-lime glass that is not discoloured by gamma radiation – unlike standard glass – but remains transparent.
Regardless of how your pipette is to be used: We can supply a suitable version. On request, the pipettes can be automatically fitted with a cotton wool filter plug that provides additional safety during pipetting operations. Open or closed tips? This decision is also yours to take. Normally, we supply pipettes with open tips. However, as protection against contamination, the tips can be closed. By means of a special ceramic blade, which is included in our product range, the tip can be opened immediately before use.
Our standard pipettes are packed in boxes which conveniently fold out on one side, offering an easy access to the pipettes. The bottom is made of smooth cardboard to ensure the utmost cleanliness of our products. Each box contains 250 pipettes. Four boxes form a unit with a total of 1000 pipettes, that are packed into a firm shipping box.
For work areas with limited capacity we offer smaller boxes containing 26 pipettes.
Strong alkaline or acid cleaning agents are often used in cleansing processes. Unlike usual plastic pipettes our glass pipettes are resistant to most solvents and cleaning agents, as well as acids and lyes. In addition to this feature, the glass pipettes are also stable during steam sterilizations, when they are exposed to pressure and high temperatures.
Plastic pipettes containing non-liquid samples which vaporize at 100°C may loose their form stability, soften and deform. During typical steam sterilizations pipettes are commonly exposed to temperatures up to 134°C and hot air sterilizations are conducted at even higher temperatures up to 180°C. Given that our glass pipettes are thermally stable and overall able to bear more heat than plastic pipettes, sterilizations can be performed without any problems. Our pipettes can even be used for pyrolytic cleaning and may be exposed to temperatures up to 500°C temporarily.
Furthermore, glass does not react with organic matter, such as somatic cells or germ cells. This is an advantage especially in the field of in-vitro fertilization. Glass also remains stable in smaller structures at high temperatures.
Overview of advantages
As a finishing touch to our product range, we also provide matching pipette bulbs. The droppers enable you to draw in or dispense small amounts of liquid easily and accurately. Here, you may also choose between two materials: Rubber or significantly more durable silicone.

To cut open closed pipettes in the application, we offer our diamond-coated blade made of ceramic. For a convenient and secure one-handed use, the blades can be clamped into our blade holders. You can find further information about our glass cutting tools here.

Our diamond-coated wire is also used for shortening pipettes. The spring effect of wires allows the slight exertion of pressure when scribing the glass component, without cracking the glass object too easily.
