Liquid Handling Tools

Introduction to Liquid Handling Tools

Liquid handling tools are a group of specialized equipment and instruments used for aspirating, dispensing, transferring, and precisely dosing liquid volumes in laboratories. This category includes various classifications such as micropipettes, bottle-top dispensers, electronic burettes, and manual or electronic pipette controllers.

Selecting the right device depends on the operating volume range (from the micro range such as 0.1-3ul to a volume of 200ml), manual operation mechanism or digital electronic display, and steam sterilization requirements at 121 °C. Buyers should also take note of technical standards such as DIN EN 285, IVD certification 98/79/EC, or the option for an accompanying DAkkS calibration certificate to meet laboratory compliance regulations. Hoa Viet currently distributes liquid handling instrument lines from Germany, including Hirschmann and Vitlab.

What is the fundamental difference between bottle-top dispensers and electronic burettes?

Bottle-top dispensers are typically mounted directly onto bottle necks to quickly distribute repetitive liquid volumes in batches. Electronic burettes are optimized for analytical titrations thanks to fine droplet control, digital displays, and recirculation systems that help prevent reagent loss.

Do liquid handling instruments at Hoa Viet meet sterilization requirements?

Many micropipette and bottle-top dispenser lines from Vitlab and Hirschmann support steam sterilization or full autoclaving at 121 °C (2 bar) according to DIN EN 285 standards. Customers should check the specifications of each specific model or contact Hoa Viet for accurate advice before autoclaving.

Which brands of liquid handling instruments does Hoa Viet supply?

Currently, Hoa Viet supplies German-origin liquid handling product lines from two brands: Hirschmann and Vitlab. Customers needing technical consultation or quotation requests can contact Hoa Viet directly.
