Desiccators ■ Vacuum desiccators come with desiccator jar, cover and stopcock with PTFE spindle; aluminum plate sold separately ■ Place your sample inside the desiccator and apply vacuum to the side arm of the stopcock ■ Simply turn the blue knob on top of the stopcock clockwise to close the desiccator ■ Once equilibrated, the cover will easily slide off
■ Due to the heavy wall thickness and the reduced thermal shock resistance under pressure, the desiccators must never be heated on only one side and never exposed to an open flame. ■ Lubricate the ground glass flange with silicone-based vacuum grease before sealing ■ A 6mm (1/4") vacuum hose (not included) is used to connect the desiccator to vacuum or gas
Vacuum Desiccators
■ Manufactured from rugged, heavy 33 extraction borosilicate glass ■ Remove stopcock and cover during storage ■ Silicone-based vacuum grease required for sealing ■ Designed for use under full vacuum ■ Do not expose desiccators to abrupt pressure changes ■ Check desiccators for scratches, cracks, and nicks before use; do not use if damage is found
