Micropipettes

Introduction to Micropipettes

Micropipettes are precision volumetric instruments used to dispense and transfer micro-volumes of liquid in laboratories. When selecting a micropipette, users should consider the operating volume range, such as 0.1-3ul or 0.5-10ul, as well as single-channel or 8-channel configurations depending on sample processing throughput.

In addition to the volume range, thermal resistance and technical certifications are essential criteria. Devices may support steam sterilization or complete autoclaving at 121 °C (2 bar according to DIN EN 285), comply with CE standards under IVD Directive 98/79/EC, or include a DAkkS calibration certificate. Hoa Viet currently supplies micropipettes from Hirschmann and Vitlab originated from Germany.

Which micropipette brands does Hoa Viet distribute?

Hoa Viet currently distributes micropipettes from Hirschmann and Vitlab, both originating from Germany. Customers can contact Hoa Viet for advice on the right instrument for specific applications.

Under what temperature conditions can micropipettes be sterilized?

Many micropipette models are steam-sterilizable or fully autoclavable at 121 °C (2 bar according to DIN EN 285). This capability ensures sterile conditions and reduces cross-contamination during analysis.

When should an 8-channel micropipette be chosen over a single-channel model?

An 8-channel micropipette is suitable for simultaneous liquid dispensing across multi-well plates to increase throughput. Meanwhile, a single-channel micropipette is the standard choice for aspirating samples into individual test tubes.

What does the CE marking under the IVD Directive 98/79/EC on a micropipette indicate?

This standard indicates that the device complies with the regulatory requirements for in vitro diagnostic (IVD) medical devices. Products meeting this standard are suitable for clinical testing and diagnostic workflows.
