Product Description

Brandtech's Dispensette S Digital bottletop dispensers have digitally adjustable dispense volumes in several volume ranges, and are ideal for accurate dispensing of acids, bases, and saline solutions, as well as many organic solvents. 

Dispensette S Product Line



Applications

  • Digital adjustment makes it excellent for labs with multiple users, which can require frequent volume changes to specific volumes. 

  • Improve speed and accuracy for routine chemical handling,  

  • Improve safety of tasks like pouring, dispensing and transferring dangerous chemicals,

  • Reduced waste of solutions which tend to crystallize in storage bottles,

  • Filling reagent tubes or small glass vessels for microbiology, 

  • Maintains sterility of liquids, especially in microbiology or cell culture applications in a bio-safety cabinet, which can require a quick withdraw, dispense and reseal of the medium bottle after each use,

  • Reduce danger of spillage within biosafety or chemical safety cabinets.  

Features

  • Digital adjustment display with simple and convenient volume adjustment knob for mechanical adjustment mechanism,

  • Displays the volume in digits on easy-to-read digital volume display,

  • Features unique Easy Calibration™ technology for calibration adjustment in seconds without tools, 

  • The "floating piston" design of the Dispensette S forms a zero-wear sealing system by using a thin film of the dispensed liquid, a few µm thick, to act as a non-wearing seal while reducing friction. This provides a smooth, easy and convenient cartridge slide which resists wear and damage, simplifies cleaning and maintenance, and provides a lifetime of reliable dispensing. 

  • Smooth dispense action makes one-handed operation safe and simple, even with a nearly-empty reagent bottle,

  • Easy to calibrate and adjust in order to comply with ISO 9001 and GLP guidelines,

  • Simple to mount discharge tube available with or without integrated recirculation valve,

  • Replaceable discharge valve with safety valve,

  • Olive-shaped filling valve for firmer attachment of filling tubes,

  • The valve design eliminates seals and is replaceable for simple, economical service and trouble-free operation,

  • A telescoping filling tube adjusts to different bottle sizes, with no measuring or cutting required,

  • Valve block rotates 360° so that the bottle label always faces the user for safety,

  • Improved flow technology results in faster priming,

  • The instrument is easy to disassemble for cleaning or full replacement of the dispensing cartridge,

  • Laboratory safety improved by mounting dispensers on reagent bottles to minimize manual pours and transfers of highly aggressive chemicals, fuming acids and highly alkaline solutions, reducing the risk of injury from inadvertent dispensing and splashes,

  • An extensive line of accessories facilitates specialized dispensing tasks like sterile applications or dispensing from large containers.  

Specifications

  • Use between +15°C and +40°C (instrument and reagent),

  • Vapor pressure up to max. 600 mbar (Aspirate slowly above 300 mbar, in order to prevent the liquid from boiling),

  • Max. kinematic viscosity:  500 mm²/s,

  • Max. dynamic viscosity [mPas] =kinematic viscosity [mm²/s] x density [g/cm³])

  • Max . density: 2.2g/cm³,

  • Autoclavable at 121°C for use with sterile reagents.

    • Instrument and distilled water at temperature equilibrium, 

    • Ambient temperature (20°C/68°F)

    • Perform a smooth operation.

  • Calibration mechanism includes a visible flag to automatically indicate when calibration has been adjusted from factory specifications.  Easy to calibrate and adjust in order to comply with ISO 9001 and GLP guidelines.

  • Dispensette® S includes:

    • Certificate of performance

    • Discharge tube

    • Valve mounting/calibration tool

    • Operating manual

    • One-year warranty

    • Telescoping filling tube, with either length of 125-240 mm (for 1, 2, 5, 10 ml) or 170-330 mm, (for 25, 50, 100 ml), 

    • Bottle thread adapters in addition to standard GL45mm thread, included adapters are provided to fit the most common lab bottle threads (mm) 24, 28, 33, 38, S40 (for 1, 2, 5, 10 ml dispensers) and 28, 33, 38, S40 (for 25, 50, 100 ml dispensers).
