Traditional Bottle Top Dispensers contain two valves with glass balls:
Inlet Valve:
This valve is vertical. It operates under gravity and does not require a spring to hold the glass ball in its position, in order to keep the valve closed.
Outlet Valve:
This valve is horizontal. It requires a spring to keep the glass ball in its position, in order to keep the valve closed while aspirating reagents in the barrel. It opens only when a reagent is being dispensed.
The spring, housed in the Outlet Valve, poses a lot of problems:
A user has to procure different kinds of Bottle Top Dispensers for different applications owing to spring metal reactivity. This proves to be an expensive proposition.
Apart from this, the spring also offers a surface for deposition of chemicals. This results in a piston jam, there by compelling the user to repeatedly clean the valve, or replace it altogether.
