Dispensette® S Trace Analysis

Product catalog summary

Overview: The document introduces the Dispensette® S Trace Analysis, a new bottle-top dispenser designed for precise volume dispensing of high-purity media for trace analysis. It highlights innovative features and trusted technology aimed at improving accuracy and ease of use.

Key Features:

Discharge Tube: Available with or without a recirculation valve, enhancing flexibility in use.
Valve System: New design eliminates the need for sealing rings, simplifying cleaning and maintenance.
Volume Selection: Utilizes an interior scalloped track for secure and repeatable volume setting.
Material Composition: High-purity materials such as PTFE, ETFE, PCTFE, FEP, and PFA are used, minimizing metal ion release.
Valve Springs: Options include platinum-iridium and tantalum, suitable for various chemicals.

Applications:

Designed for dispensing high-purity media like acids and bases in volumes ranging from 1 to 10 ml.
Suitable for trace analysis with trace metal content typically in the low ppb or ppt range.
Capable of dispensing hydrofluoric acid using a platinum-iridium valve spring.

Design and Usability:

Calibration Mechanism: Factory-adjusted with a performance certificate, no post-replacement calibration needed.
Safety Features: Includes a discharge valve with a safety ball and a 360° rotating valve block for user safety.
Adaptability: Telescoping filling tube adjusts to different bottle sizes, and the 45 mm standard thread fits common lab bottles.

Recommendations:

For trace analysis, use the dispenser without a recirculation valve to avoid contamination.
For hydrofluoric acid, discard 3-5 dispensings of 2 ml each before analysis to reduce aluminum values.

Accessories and Spare Parts: The document lists various accessories and spare parts, including telescoping filling tubes, discharge tubes, and a bottle stand, with specific catalog numbers for ordering.

Conclusion: The Dispensette® S Trace Analysis offers a combination of innovative design and reliable technology, making it suitable for precise and safe dispensing of high-purity chemicals in trace analysis applications.
