Bottletop Dispensers, Dispensette® Trace Analysis Bottletop Dispenser, BrandTech®
The Dispensette S Trace Analysis is the next generation bottletop dispenser for precise volume dispensing of high-purity media for trace analysis. It is especially suited for dispensing acids, bases and hydrogen peroxide in the volume range from 1 to 10mL. The components of the fluid path have been selected to only contain the highest purity materials, such as fluoroplastics and sapphire. The result is a trace metal content of dispensed liquid generally in the low ppb range, or even in the low ppt range, depending on the application. Both platinum-iridium and tantalum valve springs are available for application compatibility.
The Dispensette S Trace Analysis bottletop dispenser is supplied with: discharge tube, valve mounting/calibration tool, ETFE and PTFE adapters (GL28, GL32, S40), telescoping filling tube, recirculation tube (optional), performance certificate, operating manual, and one year warranty.
Dispensing of high-purity chemicals in trace analysis
- Plastics in contact with media consist of high-purity materials such as PTFE, ETFE, FEP, and PFA. The purest sapphire is used for replaceable valves. Depending on the application, platinum-iridium or tantalum are available as spring materials.
A field-tested cleaning process before use in trace analysis is described in the operating manual.
- If contamination of the bottle contents must be avoided, we recommend using the device without the removable SafetyPrime™ recirculation valve
- The 45mm standard thread plus the included adapters fits most common lab bottles
- The valve block can be rotated 360° so that the bottle label always faces the user for safety
- Telescoping filling tube adjusts to different bottle sizes
- Easy to disassemble for replacement of the dispensing cartridge
New Features:
- Simple to mount discharge tube available with or without integrated recirculation valve
- Designed without additional sealing rings for ease of cleaning and maintenance
- Replaceable discharge valve with safety valve
- Olive-shaped filling valve for firmer attachment of filling tubes
- Improved flow technology results in faster priming
- Scalloped track for secure volume setting on analog dispensers
Replaceable Dispensing Cartridge
If the piston seal is worn after a long period of use, the entire dispensing cartridge can easily be replaced without tools by the user. The cartridge is fully adjusted at the factory, and delivered with a performance certificate. No calibration is required after replacement.
Limitations of Use
This instrument is designed for dispensing liquids, observing the following physical limits:
- Use between 15°C and 40°C (59°F and 104°F) of instrument and reagent
- Density up to 3.8 g/cm³
- Vapor pressure up to max. 600 mbar; aspirate slowly above 300mbar in order to prevent the liquid from boiling
- Kinematic viscosity up to 500 mm²/s (dynamic viscosity [mPas] = kinematic viscosity [mm²/s] x density [b/cm³])
Operating Exclusions
Never use this instrument with:
- Liquids attacking Al2O3 sapphire or fluoroplastics like ETFE, FEP, PFA, PCTFA and PTFE (e.g., dissolved sodium azide*)
- Liquids which are decomposed catalytically by platinum-iridium (e.g. H2O2) or tantalum, depending on the construction of the instrument
- Organic solvents
- Trifluoroacetic acid
- Explosive liquids (e.g., carbon disulfide)
- Suspensions as solid particles may clog or damage the instrument (e.g., of charcoal)
- The Dispensette® TA must NOT be autoclaved
*Dissolved sodium azide permitted up to a max. concentration of 0.1%
