Frequently Asked Questions for AS ONE 2-4920-08 Small Vacuum Desiccator:
1/ What is the AS ONE 2-4920-08 small vacuum desiccator?
The AS ONE 2-4920-08 is a compact, rectangular vacuum desiccator made of transparent PMMA (acrylic resin). It’s designed to protect samples from moisture by evacuating air to about 133 Pa, and its inner dimensions are 95 x 40 x 136.5mm
2/ What are the key features of this model?
-
It is small, lightweight, easy to carry, supports reduced pressure gas replacement, and can be stacked with other units for efficient use of space.
3/ What materials are used for the body and seal?
The main body is made of transparent PMMA. The standard gasket is round NBR rubber, while an optional rectangular silicone rubber gasket provides enhanced airtightness.
4/ What vacuum level can it achieve?
The desiccator can be evacuated to approximately 133Pa without risking damage to the acrylic body.
5/ What valve and tubing connections does it use?
It features a hose nipple valve with an 8mm outer diameter and a one touch tube connector compatible with 6mm outer diameter tubing for quick, secure attachment.
6/ Which vacuum pumps are recommended?
AS ONE recommends the DTC-22 dry vacuum pump (model 1-4148-11) and the DA-20D dry vacuum pump (model 1-671-06). Both match the φ8mm valve nipple and φ6mm tubing connector and provide sufficient suction capacity.
7/ How do I set up and operate this desiccator?
- Ensure the gasket is clean and seated correctly.
- Close the valve and attach 6mm tubing between the desiccator and your vacuum pump.
- Start the pump, then open the valve gradually.
- Once you reach ~133Pa, close the valve fully before stopping the pump to maintain vacuum inside.
8/ How should I clean and maintain the unit?
- Wash the acrylic body with warm water and mild detergent; avoid solvents and abrasives.
- Rinse and dry completely before use.
- Inspect the gasket periodically and replace it if it loses elasticity or becomes deformed.
9/ What safety measures should I follow?
- Do not exceed a 133Pa pressure differential relative to ambient, as over evacuation can crack the acrylic.
- Avoid mechanical shocks or impacts while under vacuum.
- Place the desiccator on a stable, flat surface to prevent tipping or sliding during operation
