[ FIXED CAPACITY ]

Fixed capacity system

Accurately reproduces complicated movements for fixed capacity control

This system automates a series of tasks related to fixed capacity control for liquids, such as dispensing multiple types of liquids, performing precise fixed capacity control through image recognition, and mixing liquids. It automates tasks that are prone to variability, allowing consistent experiment data to be collected.

Operation overview

01

Container removal and cap opening

Up to 10 containers can be placed on the supply and discharge trays, allowing for up to 10 types of samples to be blended.
02

Sample container removal and cap opening

Container QR codes are scanned to acquire traceability information. Caps are opened only when required, preventing sample volatilization and contamination.
03

Pipette removal and tip attachment

Everything from tip attachment to disposal is performed automatically. Confirmation sensors are used to ensure reliable work.
04

Sample suction/dispensing

The liquid surface is detected, allowing for highly precise suction. It is capable of precise dispensing from 5 μl.
05

Nozzle removal and fixed capacity control

COBOTTA starts/stops the liquid pump and controls the amount dispensed by the pump. The advanced camera recognizes the marker and the meniscus line, allowing the system to precisely perform fixed capacity control.
06

Measurement flask closing and tumble mixing

After closing the lid, COBOTTA repeatedly turns the flask up and down to mix the sample. COBOTTA can accurately reproduce tumble mixing movements to ensure consistent frequency and trajectory.
