| Project FumeHood | |
|---|---|
| Status | In progress |
| Contact | Mux, PeterC, Thomas |
| Last Update | 2017-11-15 |
For some time now, there has been some interest in performing chemistry experiments and the like at RevSpace, with PeterC having amassed a decent amount of glassware and chemicals over the past 2 years. Unfortunately, whereas we have stockpiled quite a fun assortment of chemicals, we are still missing a lot of glassware, equipment and above all a safe environment to do proper chemistry in. Project FumeHood will change this.
This project aims to provide a complete environment to safely do a very wide variety of chemistry experiments by:
- Providing a safe fume cupboard, made from chemically inert materials, to do the experiments in
- Providing within the fume cupboard all the amenities you expect in a proper chemistry lab: electric outlets, gas connections, water connections, vacuum takeoff and of course air extraction through a carbon filter
- Providing dedicated, safe storage for glassware and chemicals
- Buying, as part of the project, a wide assortment of compatible glassware
- Buying a few necessary chemicals
- Buying, separately, a hot plate stirrer
The fume hood will be located in the Werkplaats, right next to the exit, facing the lounge.

Fume Hood construction
Some fume hood construction details:
- Table height: 85cm
- Cupboard inside height: min 95cm
- Width: min. 110cm (up to 140cm outside size is possible)
- Outside depth: 60-80cm
- Compartmentalized storage underneath fume cupboard, with doors
- Special mini-compartment with safe for extremely hazardous chemical storage
- Inside of fume cupboard is lined with glass fiber, possibly with white PC sheet cladding for easy cleaning
- Glass fiber is reinforced with aramid fiber bands for explosion-proofness
- Table is toughened glass, for easy cleaning and chemical resistance
- Two steel bars run along the back and top with holes tapped with M8 threads every 10cm; lab stand-style rods can screw into these
- Polycabonate sheet single slide-up door with glove holes, on spring-loaded linear guides and with simple up/down retaining latches
- Main skeleton out of wood
- Connections on the inside:
- 2x230V IP44 PVC outlets
- 2x barbed hose connectors for water (to water mains or circulating pump)
- 1x barbed hose connector for bunsen gas/argon
- 1x special (?) connector for vacuum take-off (vacuum pump can sit on the table besides the fume cupboard)
- Dedicated fuse box on the side of the fume cupboard?
- Soviet army style cylindrical carbon filter on the exhaust, followed by a 450m3/h or more fan
- Table has a 2cm+ lip to contain spills. Caulked or epoxied to glass fiber all around.
- Fire door. No automatic fire suppression.
Glassware
We will be ordering the following glassware, all 29/32:
- Rods, clips and connectors for latticebuilding
- 600mm Leibig condenser
- 400mm Vigureaux fractional distillation column
- 500mm Dimroth condenser
- Thermometer stopper
- Vacuum takeoff
- Parallel neck adapter
- 75 deg adapter (distillation setups, etc.)
- Glass stoppers
- Soxhlet extractor (+possibly joint)
- 50, 100, 250 and 500ml roundbottom flasks
- Keck clips
- A 500ml drop funnel (which we'll abuse as a separatory funnel as well)
- Waste bottles (soda lime glass) + caps
- Reaction plates and crucibles
What are we going to do with the fume hood?
Of course, we're not building a big, expensive project like this just for the fun of construction. We do intend on doing a fair amount of cool chemistry. A nonexhaustive list of the projects thought up so far:
- Making a lithium-ion battery (also involves project Smeltoven)
- Gold, palladium and platinum recovery from computer components using the cyanide pathway (also involves project Smeltoven)
- Chip decapping
- Making sodium and/or potassium metal using the new Nurdrage method
- Playing with project DIY solid-state stirrer
- Anodizing aluminum (and doing it right this time!)
- Making sodium silicide (for hydrogen production)
- Demonstration project: glowsticks (TCPO method)
- Demonstration project: copper salt crystal growth
- Demonstration project: basic electrolysis
- Demonstration project: Clock reaction
- Making aerogels
- Synthesizing organic and inorganic dyes
Construction
Done:
- Create the main fume hood frame
- Clad the back and sides with sheet wood to square everything
- Make the table support
- Install extendable feet
- Get a bunch more 44x44mm wooden beams
- For mounting the drawer guides
- For mounting the inner paneling
- For supporting the roof?
- Make a roof
- Size the inner paneling, do not mount yet
- Undercoat all the inner wood surfaces
- Make the latticework
- Make logically spaced 10mm holes in tube stock, corresponding holes in paneling
- De-plate nuts and weld them onto the stock
- Create a steel support plate for the fluid connections
- Undercoat all the exposed wood
Still to do:
- Make a decision on how many drawers we want, how large, if we want cabinets
- Install a lip at the front of the table
- Make the latticework
- [Partially done] Make a bunch of additional smaller holes to bolt onto paneling
- put everything together with countersunk bolts in the wood and nuts on the steel
- immobilize nuts (either with self-locking nuts or locking fluid)
- Make mounting holes for the electric outlets
- Line the inside of the fume hood with polyester resin-impregnated glass fiber. This needs to be done in sections, laying the fume hood flat on whatever side is being worked on, otherwise we're going to get droop
- Install the fluid connections
- Install the door
- Build and install drawers
- Decide on what size latticework we want and cut threads on sized pieces of stainless steel
- Install the extraction adapter, filter, ventilator
- Decide on how to decorate the outside
