with Dual Inlet® Technology

MICROLIT ULTIMUS is a Bottle Top Dispenser (BTD) that works on Dual Inlet Technology®. It offers a sophisticated blend of features and functionality, along with four modes of operation.

  • Available in Six Unique Volume Ranges


MICROLIT ULTIMUS is a Bottle Top Dispenser (BTD) that offers a sophisticated blend of features and functionality. Built by our in-house team of product design engineers, it uses Dual Inlet®, an award- winning technology patented in India, the EU and the US.

It offers 4 liquid handling modes – rinsing, dilution, refilling & purging without dismounting the dispenser.

MICROLIT ULTIMUS also features two product innovations: EasyKnob® and FlexiNozzle® that enhance its ease of use and flexibility.

Designed with ergonomics and intuitive handling in mind, it exhibits excellent chemical compatibility and helps in achieving precision with reliability in practical laboratory environments.


Modes of Operation

  • Standard Dispensing: Knob A – Open, Knob B – Closed
    In this mode, the dispenser dispenses the liquid normally into the receiver from the bottle it is mounted on.
  • Purging: Knob A – Closed, Knob B – Closed
    In this mode, the liquid is re-circulated into the same bottle on which the dispenser is mounted. This process removes the air from the dispenser, without wasting any reagent.
  • Dilution/Rinsing/Second Liquid Dispensing: Knob A – Open, Knob B – Open
    In this mode,
    the liquid from a second source can be dispensed into the receiver. The second liquid can be distilled water, thus allowing the user to rinse the instrument without dismounting it or dilute the reagent within the receiver.
  • Bottle Refilling: Knob A – Closed, Knob B – Open
    In this mode, the liquid from a second source
    can be used to refill the bottle without dismounting the dispenser.
