ALab™ DispensMate-HF Hydrofluoric Acid Bottle-Top Dispenser
Product Detail
The ALab™ DispensMate-HF is a bottle-top dispenser for hydrofluoric acid, for 1.0 to 10 mL in 0.2 mL increments. Piston, cylinder, valve ball and seat are high-purity ceramic and the tubes are FEP, so it suits HF work in trace analysis. Accuracy complies with ISO 8655.
Hydrofluoric acid is widely used in trace analysis, and it attacks glass. In the DispensMate-HF, the piston, cylinder, valve ball and valve seat are made from high-purity ceramic, while the inlet and outlet tubes are made from FEP. The valve spring is a special alloy.
The volume is set on a vernier-adjustable guide rail, and the dispenser is easy to clean. The reflux valve design reduces reagent waste and prevents leakage during idle periods. Bottle adapters S40, GL32, GL38, GL25 and GL28 fit common reagent bottles.

Where it fits
Frequently asked questions
Why a dedicated dispenser for HF?
Hydrofluoric acid attacks glass. The DispensMate-HF uses high-purity ceramic for the piston, cylinder, valve ball and seat, FEP tubes and a special-alloy valve spring.
What volume range does it cover?
1.0 to 10 mL in 0.2 mL increments, set on a vernier-adjustable guide rail.
How accurate is it?
At 10 mL, the systematic error is 0.5% (50 µL) and the random error is 0.2% (20 µL). Values at 5 and 1 mL are listed in the accuracy table.
Which bottles does it fit?
It is compatible with S40, GL32, GL38, GL25 and GL28 bottle adapters.
Does it have a reflux valve?
Yes. The reflux valve design reduces reagent waste and prevents leakage during idle periods.
