- Plain Desiccators are physically the same as Vaccum desiccators.
- Only difference is the absence of stop cock. Grease should be applied on the flanges to make it air tight.
- Both Vaccum & Plan Desiccators are provided with a thick perforated Polypropylene disc with a big hole in the centre for easy lifting.
- The tiny holes in the disc provide air troughs & support to the dishes.
- However porcelain discs are advisable in case of incandescent crucibles.
