Benchtop vs. Bulk Delivery Systems

Aeris Precision Benchtop systems withdraw their chemicals from bottles sitting inside its internal chemical bay. The systems can accomodate most typical "1 gal" bottles or smaller. The bottles easily hook up to the system using MATECH's patented no-drip quick release bottle interface. This bottle inteface prevents drips and splashes during bottle changes, thus further reducing operator risk.

Also, the benchtop systems deliver the chemicals to a removable reservoir or beaker of up to one gallon in size. The system automatically fills the beaker with whatever volume, or volume ratios, of one or more of the three channels available. For example, the user can request 2 liters composed of: 3 parts of channel 1 chemical, 2 parts of channel 2 chemical and 1 part of channel 3 chemical. It takes approximately 1 min to prepare the mix with an accuracy of approximately 0.25-0.5 ml.

The sytem's interlocks will prevent operation if the doors are open, if there are empty bottles (optional), if there is no receiving reservoir in place, or if the reservoir has no sufficient volume left to accomodate the requested volume.

Bulk Aeris Precision Systems take their chemicals from external "delivery" bays or cabinets. Depending on the user's needs, the bays can be of three sizes: 55 gal drum size, 5 gal carboy size, and "1 gal" bottle (or smaller) size. Of course, the user can mix and match the bay sizes according to his or her needs and expand or exchange them as the requirements change. The control console can handle up to 12 individual chemical channels in any combination, thus making expansion extremely cost effective.

All chemical containers easily hook up to the system with MATECH's patented no-drip quick release bottle interface. This bottle interface prevents drips and splashes during drum, carboy, or bottle changes, reducing operator risk. Large bays have glove sleeves to further protect the operators during drum exchanges or maintenance.

The Aeris bulk systems deliver the chemicals to a fixed reservoir from one gallon to five gallon in size--depending on the customer requirements. The system automatically fills the receiving reservoir with whatever volume, or volume ratios, of one or more of the 3-12 channels available. For example, the user can request 6.72 liters composed of: 3 parts of channel 1 chemical, 2 parts of channel 2 chemical and 1 part of channel 3 chemical. It takes approximately 3 min to prepare the mix with an accuracy of approximately 0.5-1.0 ml.

The receiving reservoir can also be temperature controlled and agitated (both options). The mixed chemicals stay in the receiving reservoir for the amount of time defined by the operator or until specified conditions are reached (i.e. a specific temperature). From there they are pumped to the specified destination, tool, system, bath, etc. Every operation is under program control.

Alternatively, the Aeris bulk system can deliver the chemicals directly to a destination external to the Aeris system. Metering can be also performed at this external location (option).

The sytem's interlocks will prevent operation if the doors are open, if there are empty containers (optional), or if the receiving reservoir does not have enough volume available to contain the new volume requested.
