The Goldleaf Scientific hand-driven bottle-top burette is a convenient tool for continual or repetitive dispensing or metering of liquids on a precise scale. Titration, dosing, or dispensing of liquids is made fast, easy, and precise. Meets or exceeds the precision requirement of the Class A standard for ASTM E287-02 (2007) “Standard Specification for Laboratory Glass Graduated Burets”

Easy to read digital display Electronic measuring system with display to 2 decimal places and now with Titrate mode and Dosing mode. The bottle top burette is suitable for all common laboratory bottles and can be programmed by computer via the built in RS-485 connection. Use your computer to control, monitor, and keep records that might be real useful to recover possible errors.

Goldleaf’s bottle-top burets are easy to program, easy to clean, and easy to operate.  This bottle-top burette also features a valve-less dosing system design which results in the lowest possible dead volume and high reproducibility, and can be individually calibrated to your specifications (calibration function enables adjustment to media with a density that differs significantly from water).

  • Permanently stored data of factory calibration
  • Drying tube connection
  • Light weight and compact
  • Smallest individual steps 1μl, 10 μl, 20 μl (depending on model)
  • No glass bulb, no valves, minimal dead volume
  • self-venting
  • Parts in contact with media made of acid-resistant aluminum oxide (99.7% Al 23 ), ETFE and FEP
