Questions

Can I Modify the Clamshell Process Chambers?

YES.

• The clamshell process chambers (sold separately) are simple and easy to modify.

• The plastic can be cut to customize the box to fit individual process

requirements.

• The boxes are disposable. If the box becomes soiled or damaged,

replacements are readily available from EFD.

Can I Make My Own Process Chamber?

YES.

For those who wish to make their own process chamber, please follow

the guidelines outlined below:

• The chamber should cover the entire material path (syringe, valve, fittings, etc,

leaving only the needle or exit point exposed).

• The chamber should have a minimum of “dead air” space. The less space

inside the chamber, the easier it is to maintain temperatures within.

• The chamber should allow the heated/chilled air to circulate freely around the

process hardware within.

• The chamber must have a vent that allows air to exit the chamber. Plan ahead

to determine where the heated/chilled air can freely enter, circulate, and then

exit the chamber.

• The chamber should either be made of transparent materials, or be provided

with a window to allow monitoring of material levels.

• In order to maintain temperatures well above or below ambient conditions, the

chamber should be made from or contain an insulated material or have double-

walled construction. This will help to maintain desired temperatures.
