Isocyanate is dripped into alcohol in urethane synthesis tests. The drip speed is 1 mL/min.
Conventionally, a micro syringe pump was used, which posed the following problems.

• The pump was made outside of Japan, so there are few syringes made in Japan that are compatible with it.
• The syringe is made out of glass, so it breaks easily and is difficult to handle.
• Pump preparations are bothersome, so even though there are researchers who perform dripping by hand, it is difficult to perform dripping with a constant speed.

We suggested that the customer use a “Q Series” Smoothflow Pump for small volume supply, and they agreed to this proposal.

• Accurate dripping with a speed of 1 mL/min is now possible.
• Accurate dripping was even possible when we tried an even smaller amount (0.3 mL/min).
• Compared to the conventional pump, the Smoothflow Pump is overwhelmingly easier to prepare and operate.
