Globe Scientific is pleased to offer these implosion proof vacuum and filtration dessicators. They are an excellent alternative to glass dome and porcelain desiccators and offered at a much lower price.
The desiccator comes complete with a removable pan for holding drying agents. The lid contains an integrated vacuum release/non-return valve assembly. The specially grooved stopper allows required air to be re-admitted very slowly to avoid disturbing the contents.
