About This Product
A bottle-top dispenser screws onto a reagent bottle and delivers repeated, set volumes of liquid by moving the plunger, which saves pouring and pipetting when the same volume is needed many times. In a school or college lab it is used for dispensing reagents during practical sessions and preparation work. Adapters let the one unit fit bottles with different neck sizes, and the chemical compatibility of the wetted parts should be checked against the reagent being dispensed. Alongside supply within India, the Dispenser Bottle Top Research Grade is offered for export to Seychelles, Montenegro, Paraguay, Rwanda, Cyprus and United Kingdom.
