Application
The BOECO SA dispenser supports a very wide range of applications for the dispensing of aggressive reagents – directly from the supply bottle:
Such as concentrated bases and acids like H3PO4, H2SO4 (with certain exceptions such as HCL, HNO3, HF, etc.), saline solutions, and a variety of organic solvents.
Specially for use in trace analysis for dispensing high-purity and highly concentrated acids and salt solutions, acids, alkalies and many organic solvents as well as hydrogen peroxide, bromine.

BOECO GP Series bottle-top dispensers are instruments with proven
precision that offer many advantages in routine liquid-handling operations.
The positive displacement piston in this instrument is equipped with a
fluoroplastic (PFA) sealing lip on the cylinder wall. This acts like a windscreen
wiper to prevent crystal build-up on the cylinder wall from readily crystallisable
media. The glass cylinder is also coated with a plastic material that reduces
the risk of splashes should breakage occur. The telescopic filling tube can be
adjusted smoothly to the height of the bottle.
Since the materials in contact with the media (Borosilicate glass, AI2O3ceramic,
ETFE, FEP, PFA, PTFE, platinum- iridium, PP (closure cap) are resistant to most acids, bases, and solvents, BOECO GP Series bottle-top dispensers can be used in practically any operation with salt solutions, acids, bases and many organic solvents.
BOECO GP Series bottle-top Dispensers are completely autoclavable at 121°C (2 bar) according to DIN EN 285
Also available with DAkkS calibration certificate or individual quality certificate.
