Glassware Calibration

Glassware Calibration

Accurate calibration of glassware, such as volumetric flasks, pipettes, and burettes, is essential to ensure accurate measurements in the analytical laboratory. Calibration helps maintain consistency across measurements and prevents errors arising from inaccurate volumes.
Volumetric flasks: Volumetric flasks are designed to prepare aqueous solutions of precise volumes accurately with a calibration line on the neck. To calibrate a volumetric flask, it is important to fill it with distilled...

Area of Science:

Biotechnology
Laboratory Automation
Open Source Hardware

Background:

High cost of proprietary bottle rollers limits accessibility in research.
Need for affordable, customizable laboratory automation solutions.

Purpose of the Study:

To design and fabricate an open-source bottle roller using 3D printing and accessible components.
To provide a cost-effective and robust alternative to commercial bottle rolling systems.

Main Methods:

Utilized distributed digital manufacturing with 3D-printed parts and commercial components.
Designed for compatibility with low-profile incubators and elevated temperatures.
Tested rotational speed range (1-200 RPM), capacity (1.2 kg, 12x100 mL bottles), and long-term stability.

Main Results:

Fabrication cost of $210 CAD (approx. $150 USD), an 86% cost reduction.
Demonstrated robustness, adaptability, and compatibility with standard laboratory equipment.
Achieved reliable operation for extended periods (days) at various speeds and temperatures (up to 50°C).

Conclusions:

The open-source bottle roller offers a significantly cheaper, more capable, and adaptable solution for laboratory automation.
This design democratizes access to essential lab equipment through digital manufacturing.
Further development will focus on cost reduction and increased fabrication flexibility.
