NEW! Dispensette® S Trace Analysis Bottletop Dispenser

Product and ordering information for the Dispensette S Trace Analysis bottletop dispenser for accurate and precise dispensing of high purity laboratory chemicals and reagents.

Catalog #: N/A Category:
   

Description

NEW! 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 10 mL. 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.

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

Product No. & Specs



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.

FAQS

What can I dispense with the Dispensette® S Trace Analysis?

The Dispensette® S Trace Analysis is specially designed to dispense high-purity chemicals, with trace metal content of dispensed liquid generally in the low ppb range, or, depending on the application, even in the low ppt range. The platinum-iridium model is suitable for dispensing Hydrofluoric acid (HF), while the tantalum model is suitable for dispensing Hydrogen peroxide (H2O2). Additionally, the Dispensette® S Trace Analysis can be used to dispense Bromine since the ball valve, composed of Al2O3 sapphire, is denser than the ball valves in the Dispensette® S or Dispensette® S Organic. See the Dispenser S Trace Analysis selection chart for a complete list of compatible reagents: click here.

My Dispensette® S Trace Analysis seems to leak at the base, especially after priming. How do I stop this?

It's probable that the recirculation tube was not reinserted into the underside of the instrument. This directs liquid down the side of the bottle, to help keep from generating additional bubbles when priming. When absent, some liquid can dribble down the side of the instrument. If you need a replacement, the part number is 6747 and can be ordered from your favorite supplier.

My Dispensette® S Trace Analysis is drawing up bubbles and liquid? What should I do?

Your Dispensette® S Trace Analysis has an air leak somewhere. Good places to look are at the junction of the filling tube and filling valve. If it does not make a tight seal, trim some of the tube off, and reattach. Check to see if the filling and discharge valves are tight. Lastly, is there any liquid in the bottle?

The cylinder of my Dispensette® S Trace Analysis doesn't fill. What is happening?

There are several different causes that could keep a Dispensette® S Trace Analysis cylinder from filling: 1) The discharge tube is not fitted properly. Check to ensure it is attached properly. 2) The filling valve is not tight or the filling tube is not pushed in enough. 3) The filling valve is dirty and/or stuck. This case can be determined easily because the Dispensette® S Trace Analysis piston will be difficult to lift, and it gets "sucked back down" when released. If the filling valve is dirty, clean the valve. If it is simply stuck, follow the instructions in the Operating Manual for loosening the ball valve (under 'Replacement of discharge tube/valves').

I can fill the cylinder, but it won't dispense. Why?

The discharge valve is probably stuck. Remove the discharge tube and discharge valve, and clean the discharge valve. If necessary, replace the discharge valve.

Is the Dispensing Cartridge replaceable?

Yes. The Dispensing Cartridge for the Dispensette® S Trace Analysis is a replacement part. It is catalog number 708035 - Dispensing Cartridge with Safety Ring - and comes calibrated with a quality certificate.

All through the catalog, it mentions that the "Standard Operating Procedure" for instrument calibration is available. How do I get one?

The SOP for the Dispensette® S Trace Analysis is available here. Additionally, all of the SOP's for BRAND's liquid handling instruments, as well as the BLAUBRAND volumetric glassware are compiled in EASYCAL™ 4.0 for easy reference.

Tech Info

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%)
