Size 11 Piston Pump
Micro volume dispensing piston pump has the smallest size, we have four kinds of dispense volume(100uL, 250uL, 500uL, 1mL).
Small overall dimension, applied to removable sampling robotic arm for accurate dosing.
Less leakage risk as fewer tubes and connectors installed;
No air bubble;
High accuracy and consistency;
Small size;
Easy to install.

Description of the Liquid Aspiration Sequence:
STEP 1: The two-way N.C. solenoid valve SV1 is powered on, and the branches on both sides of the two-way valve SV1 open.
STEP 2: After 40 ms, the piston pump PP1 sends a pulse to control the plunger to aspirate liquid (Note: In this sequence, +U is used to represent the control of the plunger's retraction).
STEP 3: After the liquid aspiration instruction is completed, the piston pump PP1 is powered off and stops working.
STEP 4: After 40 ms, the two-way valve SV1 is powered off, and the branches on both sides are disconnected.
Description of the Liquid Dispensing Sequence:
STEP 1: The two-way normally closed solenoid valve SV2 is powered on, and the branches on both sides of the two-way valve SV2 open.
STEP 2: After 40 ms, the piston pump PP1 sends a pulse to control the piston to dispensing liquid (Note: In this sequence, -U is used to represent the control of the plunger's extension).
STEP 3: After the liquid dispensing instruction is completed, the piston pump PP1 is powered off and stops working.
STEP 4: After 40 ms, the two-way valve SV2 is powered off, and the branches on both sides are disconnected.
