Dispensette S bottletop dispensers build on the fifty year history of BRAND dispensing expertise.

  • Continual upgrades makes this the safest and most convenient bottletop dispenser ever, all while retaining the features that make the Dispensette the world’s favorite bottletop dispenser.
  • They mount directly on most solvent and reagent bottles for faster, more convenient dispensing.
  • Instruments are autoclavable at 121ºC (250ºF) for use with sterile reagents.
  • Dispense most lab reagents:
  • - Choose the Dispensette S for acids, bases, saline solutions, as well as many organic solvents; the Dispensette S Organic for organic solvents, including combinatorial chemistry solvents, concentrated acids such as HCl and HNO3, trifluoroacetic acid (TFA), tetrahydrofuran (THF), and peroxides.
  • Deliver accurate, precise volumes: Dispensers are accurate to 0.5% (0.6% for 1mL models), with coefficients of variation of 0.1% (0.2% for 1mL).
  • - Digital models feature accurate and reproducible volume settings via a mechanical digital display.
  • Increase laboratory safety:
  • - Dispensers mount on reagent bottles to reduce poured reagent transfers.
  • - They include a number of safety features to reduce the risk of injury from inadvertent dispensing and splashes.
  • - Recirculation valve system enhances reagent conservation and safety.
  • - Many accessories are available for remote, serialand drum dispensing.
  • Resist wear and damage: Unique design ensures smooth operation and eliminates wearing parts.
  • - Dispensers disassemble easily to simplify cleaning and maintenance.
  • - The new system eliminates seals for a lifetime of reliable dispensing.
  • HF and trace analysis dispensing:
  • - For dispensing of high purity acids and solvents, or hydrofluoric acid, choose the Dispensette S Trace Analysis.

Analog-adjustable models.

  • Analog slide enables rapid volume adjustments.
  • Internal scalloped track helpssecure setting.
  • Calibration adjustments are simple with included tool.

Digital models.

  • Digital models enable accurate and reproducible volume setting with an easy-to-read display and a convenientadjustment knob.
  • - Simply turn the knob.
  • - The mechanical adjustment mechanism displays the volume in digits.
  • Features unique calibration technology for calibration adjustment in seconds without tools.
  • Excellent for labs with multiple users, requiring frequent volume changes to specific volumes.

Fixed-volume models.

  • Fixed-volume for standardized applications.
  • Calibration adjustments are simple with included tool.

Product Features:

  • Both the Dispensette S and Dispensette S Organic are constructed using the “floating piston” principle.
  • - Each piston is matched with precise tolerances to the cylinder of the instrument.
  • - A thin film of the dispensed liquid of just a few µm thick acts as a non-wearing seal that reduces friction, so dispensing is easy and convenient.
  • The GL45mm standard thread, plus included adapters, fit most common lab bottles.
  • The valve block can be rotated 360° so that the bottle label always faces the user for safety.
  • A telescoping filling tube adjusts to different bottle sizes.
  • The instrument is easy to disassemble for cleaning.
  • Valves are replaceable for simple, economical service.
  • New valve design eliminates seals for trouble-free operation.
  • Dispensette S and Dispensette S Organic are autoclavable at 121°C.
  • Easy to calibrate and adjust in order to comply with ISO 9001 and GLP guidelines.
  • - A positive indicator automatically indicates adjustment from factory settings.
  • An extensive line of accessories facilitates specialized dispensing tasks like sterile applications or dispensing from large containers.

Applications.

  • One-handed operation : “Floating piston” design eliminates the seals that often wear and fail on other dispensers.
  • - This allows the Dispensette S piston to move very smoothly, permitting safe, simple, one-handed dispensing, even with a nearly-empty reagent bottle.
  • Dispensing sterile fluids:
  • - Dispensette S and Dispensette S Organic bottletop dispensers are autoclavable at 121ºC (250ºF) and can be fitted with an optional microfilter to prevent contamination of bottle contents.
  • - Sterile technique must be followed.
  • Serial dispensing:
  • - The optional flexible discharge tube with safety handle speeds serial dispensing tasks, and permits fast and precise dispensing even into narrow test tubes.
  • - Integrated recirculation valve helps purge bubbles before use.
  • Dispensing sensitive reagents:
  • - Optional drying tube screws into the accessory port of the Dispensette S to protect sensitive reagents from humidity or CO2 (Absorbing agent not included).

Dispensing from bulk containers minimizes risk of contaminating high-purity reagents.

  • Simply connect the Dispensette S or Dispensette S Organic to the optional Remote Dispensing System for accurate dispensing from drums and other bulk containers up to 10 meters away.
  • - Maximum delivery height is 1.2 meters.
  • - A quick-release connector with integrated valves simplifies changing the bulk container.
  • - The drum adapter air inlet filter minimizes risk of contaminating high-purity reagents.
  • NOTE: Not for use with recirculation valve, pressurized vessels, peroxides (which will react with the platinum-iridium spring), HF or other liquids which attack borosilicate glass, alumina ceramic, PFA, ETFE, FEP or PTFE.
  • - Observe all safety instructions, operating exclusions, and limitations of your specific operating manual of the Dispensette S bottletop dispenser model.

Operating limitations.

  • Liquids which form deposits may make the piston difficult to move or may cause jamming (e.g., crystallizing solutions or concentrated alkaline solutions).
  • When dispensing inflammable media, make sure to avoid the buildup of static charge, (e.g., do not dispense into plastic vessels; do not wipe instruments with a dry cloth).
  • The Dispensette is designed for general laboratory applications and complies with the relevant standards, e.g., DIN EN ISO 8655.
  • - Compatibility of the instrument for a specific application (e.g., trace material analysis, food sector, etc.) must be checked by the user.
  • - Approvals for specific applications, (e.g., for production and administration of food, pharmaceuticals and cosmetics) are not available.

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.
  • - Vapor pressure up to max. 600mbar. Aspirate slowly above 300mbar, in order to prevent the liquid from boiling.
  • - Kinematic viscosity up to 500mm2/s (dynamic viscosity [mPas] = kinematic viscosity [mm2/s] x density [g/cm3]).
  • - Density: Dispensette S/Dispensette S Organic: up to 2.2g/cm3.
