QC–S sampling unit for ultra-pure sample collection

With the QC-S sampling unit, the sample liquid only comes into contact with the suction hose and the sample bottle (accessories). Cross-contamination is largely prevented. Using the gas recovery line that can be fitted, chemical vapours and liquids are effectively fed back into the container from the pump cylinder. The bottles are immediately sealed after the sampling process. The disposable suction hose made of PFA can be quickly replaced. This ensures that unmixed samples are taken in each case. If required, a new hose is used for each sample. Using a QC-1 Dispense Head makes the QC-S sampling unit a safe, simple and flexible connection to all QC-System dip tubes belonging to the QC-2 product line. Using corresponding adapters, a large number of sample bottles can be connected.

  • Ideal when it comes down to ultimate purity.
