Welcome to OpenDeskLab’s documentation!¶
Project Description¶
OpenDeskLab aims at creating an open design for laboratory desks that is
- Modular structure
- Reconfigurable dimensions
- Safe
- Easy to build
- Low cost
- Highly functional
The material used for the structure of is mostly melamine boards, that can be precut by any CNC supplier to the given dimensions. The assembly of an OpenDeskLab is designed so as to require only the basic of the tools, such as a Pozidriv screwdriver. The desk itself can be configured in many different ways, and the materials as well as the aesthetics can be customized according to the owners taste.
All the materials chosen for the OpenDeskLab (and their respective sockets) are dimensioned according to the International standards and can be sourced online or in many local stores. The desk can be assembled easily, following the instructive videos provided for each component. Various components are provided, although anyone can design his own component to pair with the already developed ones.
OpenDeskLab can be built in three, four and five module variants. The builder may choose the modules that will form his desk according to his needs, and the modular design will accommodate every customization (with some minor limitations) possible.
Applications¶
The main audience that OpenDeskLab targets are high school laboratories and home/diy/hackerspace/fablab places. Due to its’ modular nature, OpenDeskLab can be used in a variety of applications, including (but not limited to) electrical, chemical and general use workbenches. It can provide electrical as well as gas connections, water supply and drain and of course ventilation. A hazardous materials storage is also provided that is the only fully self-contained module that can provide a safe storage for chemicals and flammables.
Specifications & Requirements¶
According to the rules and regulations of the EU and most International Standards committees, there are some safety rules that must be taken into account for manufacturing laboratory equipment. However, although OpenDeskLab is designed according to those rules, it must be noted that the authors and creators of OpenDeskLab are not eligible for any kind of damage that may happen while building or using the desk. A laboratory that is used in professional environments must be certified by an authorized person, and OpenDeskLab is neither certified nor can fullfil all the regulations of every standard in the world.
Warning
OpenDeskLab is not certified for professional use. The authors are not eligible for any damage that may occur while building or using the product.

Module List¶
Cable Routing¶
The cable routing module lies on top of the worktop, providing power and air connections for the users. The width of the melamine parts depends on the number of modules the desk will be built with.
Important
- Tools Needed:
- Pozidriv Screwdriver
- Wire Cutter
- Tube Cutter
- Scissors
When choosing the appropriate connections (for electricity and pneumatics) choose the appropriate plugs for your country and the correct International Protection Marking (IP Code). In laboratory environments, IP54 is the minimum requirement, and in some cases even more strict protection might be required.
IP Code Object Protection Liquid Protection 0 No protection No protection 1 >50 mm Dripping water 2 >12.5 mm Dripping water when tilted up to 15° 3 >2.5 mm Spraying water 4 >1 mm Splashing of water 5 Dust protected Water jets 6 Dust tight Powerful water jets 6K N/A Powerful water jets with increased pressure 7 N/A Immersion up to 1 m 8 N/A Immersion beyond 1 m 9k N/A Powerful high temperature water jets
Warning
Electrical connections must be made from an authorized electrician. The authors are not responsible for any damage or incorrect installation by the builders.
Assembly Procedure¶
The assembly of the cable routing module is perhaps the hardest part of OpenDeskLab, as it requires electrical as well as pneumatic connections. The front melamine part has predrilled holes that can be used to connect AC or DC eletric outlets or switches for the Lighting and Ventilation module.
The pneumatic connectors are predrilled on either side of the electric outlets, and can be configured either as input/output connects or as outputs only.
The cable routing module provides 3 electric connections and two pneumatic connections above each module, therefore providing 9 electric and 6 pneumatic plugs for the three module-wide desk.
Cable management for all the connections goes through the Desk Back to their respective sources.
Drawings¶
Drawings are provided for the three module-wide version, for the other versions nothing changes besides the overall length of the module.
