Most small-scale and laboratory-scale tests are performed at Gexcon's test laboratory facilities at Fantoft near Bergen, Norway. A wide range of gas and dust explosion testing projects using vessels in the volume range from less than 1 litre to approximately 2 m3 can usually be performed in the laboratory. In this wide range of test vessels, test scenarios can be varied significantly. Several closed vessels are available as well as a number of open or vented test vessels.
Small-scale testing at Gexcon includes both equipment testing, gas and dust explosion research as well as specialised or dedicated testing projects that are tailor-made to suit customer requirements and needs.
The small-scale test facilities at Gexcon's test laboratory include, among others, the following test vessels:
- 2.0 litre cylindrical vessel (L = 0.25 m, D=0.1 m, Pmax = 10 barg)
- 9 litre cylindrical high pressure vessel (L = 0.3 m, D = 0.2 m, Pmax = 200 barg, flanged ends)
- 20 litre spherical dispersion chamber (D=0.35 m, Pmax = 16 barg)
- 1.4 m repeated obstacle vessel (L=1.4 m, 0.3 x 0.3 m, approx 130 litre volume)
- 1:33 scale module (L=1.2 m, 0.35 x 0.40 m, approx. 170 litre volume)
- Transient driver section (L=3.5 m, 0.3 x 0.3 m, approx. 315 litre)
- 1.2 m3 vessel (D = 0.9 m, L = 1.9 m, Pmax = 13 barg, closed vessel or open end with variable venting configurations)
- 1.5 m3 rectangular cabinet for equipment testing (H=1.5 m, 1.0 x 1.0 m, flange at top and a variety of vent arrangements on sides)
- Single-impact anvil test apparatus
- And several other test vessels and apparatuses

Testing is typically performed with propane, hexane or ethylene but other gases or liquids can also be used.
