The Labcold Sparkfree range is engineered to store flammable materials safely with no sources of ignition inside the chambers. Everything that could conceivably cause a spark, such as the controller, is located outside of the freezer chamber making these freezers an important part of laboratory safety. Designed specifically for laboratories, these freezers are solidly built and come in both upright and chest configuration. All Labcold Sparkfree freezers and chest freezers are factory fitted with a door lock for optimum security.
