Njbinglab PTFE Chemical Sampling Unit Without Cross Contamination for Aggressive Liquid Chemicals

Key Features of PTFE Acid Dispensers

High Corrosion Resistance: Stable against strong acids and oxidants such as aqua regia, HF, and HClO₄.

High Cleanliness: No metal ion precipitation, suitable for trace analysis (ppb and ppt levels).

Convenient Liquid Dispensing: Safely dispense acid from large bottles using threaded connections or vacuum pressure.

High Safety: Eliminates the dangers of manually pouring acid from large bottles, reducing splashing and evaporation.

Common Types

Negative Pressure Acid Dispenser

Used with a vacuum pump, it draws acid into small PTFE bottles using negative pressure.

Suitable for dispensing high-purity acids.

Siphon Acid Dispenser

Integrated PTFE tubing for gravity-assisted siphoning.

Suitable for transferring acid from large barrels.

Piston Acid Dispenser

Equipped with a PTFE piston control switch, it dispenses acid like a tap.

Used for quantitative dispensing of small to medium volumes of acid.

Application Scenarios

Non-ferrous metal sample pretreatment: Separating high-purity acid for sample dissolution.

Semiconductor/photovoltaic industry: Repackaging of bulk acid and transfer of purified acid.

Environmental testing, geology, and research laboratories: Trace element analysis (ICP, ICP-MS, AAS pretreatment)
