BÜRKLE disposable pipettes LDPE
The BÜRKLE disposable pipettes LDPE are ideal for laboratory applications where clean and precise aspiration of small liquid samples is required. Compared to reusable glass or plastic pipettes, they are particularly economical as they eliminate the need for time-consuming cleaning processes and the risk of cross-contamination. Thanks to their ungraduated dropper tips, they are primarily designed for quick and easy sampling, but also impress with their high functionality and reliable handling.
Properties and design
Disposable pipettes made of low-density polyethylene (LDPE) are flexible, chemically resistant and at the same time dimensionally stable enough to enable precise dispensing. Users benefit from both easy handling and clear drip control. Thanks to the smooth surface material, the risk of sample residue remains low. This is particularly important in sensitive areas such as pharmaceuticals, biotechnology or food analysis, where precise results are required.
These pipettes also offer a practical advantage thanks to their different size variants. Depending on the specific requirements in the laboratory, suitable versions with different working volumes and lengths can be selected. As LDPE is chemically inert to many substances, a wide variety of liquids can be pipetted safely and without contamination. Despite its disposable nature, reliable quality is guaranteed so that users always achieve reproducible results.
Technical data at a glance
- Material: LDPE (low-density polyethylene)
- Type: drip tips, ungraduated
- Length: 98 mm, 145 mm or 155 mm (depending on model)
- Volume: 1.8 ml, 1.7 ml or 2.4 ml (depending on model)

The parameters listed here cover important areas of application in everyday laboratory work. Their ungraduated dropper tips make it easy to take samples, while the flexible design of the pipettes allows fine adjustment of the drop size. Users who attach greater importance to exact quantities can calibrate certain volumes in advance or use additional measuring devices for control purposes.
Special standards and quality
Since laboratories often have the highest requirements for product safety and hygiene, disposable pipettes are subject to strict quality standards. The robust LDPE material withstands typical stresses caused by moderate temperature ranges and contact with common laboratory chemicals. Although these pipettes are ungraded, they meet the usual requirements for professional use, for example in clinical laboratories, research facilities or quality assurance.
Examples of use
- Sample collection in microbiology laboratories: For the safe transfer of nutrient solutions, cell cultures or buffer solutions.
- Routine analyses for drinking water tests: Allows indicator liquids or reagents to be added drop by drop.
- Chemical process control: Easy sampling of acids, bases or aqueous solvents to perform quick tests and titrations.
- Pharmaceuticals and cosmetics: Precise dosing of individual substances such as oils, lotions or active ingredient solutions in development phases.
FAQs
What is the best way to dispose of pipettes?
After use, the LDPE pipettes are usually disposed of with the plastic waste or according to the in-house disposal system. In the event of contact with infectious material, a special disposal route must be ensured.
Can disposable pipettes be used several times?
They are primarily designed for single use, as reliable cleaning is complicated and not economical. For consistently high purity, it is recommended to always use a new pipette, depending on requirements.
Are there any restrictions with certain chemicals?
LDPE is resistant to many aqueous and slightly alkaline or acidic media. In the case of strongly oxidizing or organic solvents, it should be checked in advance whether an interaction can occur.
Are the pipettes autoclavable?
The material can only withstand high temperatures to a limited extent. As a rule, they are not recommended for autoclaving processes, as single use does not require thermal sterilization.
Conclusion
These disposable pipettes made of LDPE are a cost-effective solution for handling liquids quickly and cleanly without the need for time-consuming pipette cleaning. Their chemical resistance, flexibility and availability in different volumes make them a versatile tool for laboratory environments in a wide range of industries - from drinking water analysis to pharmaceutical research and food control. Their ease of use combined with the reliability of a single-use product means that users are well protected every time they use them and enjoy a smooth, high-quality workflow.
