Bottle Top Dispenser | Sapphire  with Dual Inlet Technology

Save time and increase lab productivity using the Sapphire Bottle Top Dispenser. This convenient dispenser uses a dual valve technology that allows you to simply rinse the instrument and refill your bottle without dismounting the dispenser!

Featuring functionality, user-friendliness and performance, the Sapphire Bottle Top Dispenser operates in four modes: Dilution, Rinsing, Dual Liquid Handling and Re-circulation.

Six unique volume ranges:

  • 0.25 - 2.5 ml
  • 0.5 - 5 ml
  • 1 - 10 ml
  • 2.5 - 30 ml
  • 5 - 60 ml
  • 10 - 100 ml

Fully Autoclavable at 121°C, 15psi. for 10 - 15 mins.

Sapphire offers four modes of operation:




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.



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.



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 from the bottle or for dilution of the reagent in the receiver.



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
