Overview of the AirClean AC23238
The AirClean Systems AC23238 provides a specialized containment workspace for laboratories using rotary evaporators and other equipment involved in solvent evaporation.
Rotary evaporators are widely used in chemistry, pharmaceutical research, environmental testing, and analytical laboratories to concentrate samples and recover solvents under reduced pressure.
Although these instruments typically incorporate condensers and receiving flasks to collect evaporated solvents, chemical vapors may still escape during operation, flask changes, equipment adjustments, and solvent collection.
The AC23238 provides an enclosure around the rotary evaporator, allowing an appropriately designed exhaust system to capture and remove these vapors from the immediate laboratory environment.
Its relatively compact footprint makes it useful for laboratories that want a dedicated rotary evaporation workstation while preserving larger chemical fume hoods for other procedures.
Designed for Büchi and Heidolph Rotary Evaporators
One of the distinguishing characteristics of the AirClean 200 Series rotary evaporator enclosure is its equipment-focused design.
The AC23238 is intended to accommodate rotary evaporators, including selected instruments manufactured by Büchi and Heidolph.
Its interior configuration provides space for the major components of a typical rotary evaporator assembly, including the rotating evaporation flask, condenser, receiving flask, and associated support equipment.
The enclosure's front access arrangement allows operators to interact with the instrument while keeping much of the equipment surrounded by the containment structure.
Because rotary evaporators vary in height, condenser orientation, flask capacity, and accessory configuration, laboratories should verify the actual dimensions of their instrument before purchasing the enclosure.
Compatibility with a particular Büchi or Heidolph model should not be assumed solely from the manufacturer name.
Two-Tier Front Access Doors
The AC23238 incorporates a distinctive two-tier front door arrangement designed to provide convenient access to enclosed equipment.
The lower doors measure approximately 16.25 inches high, while the upper doors measure approximately 10.25 inches high.
This configuration allows operators to access different portions of a rotary evaporator assembly without necessarily removing the entire front panel.
For example, the lower section can facilitate access to evaporation flasks, collection vessels, and lower equipment components, while the upper section provides access to condensers, connections, and other elevated parts of the apparatus.
This design can be especially convenient for procedures requiring frequent sample changes or adjustments to the rotary evaporator.
During operation, the doors should be positioned according to the airflow requirements established for the complete exhaust system.
Removable Front Panel for Equipment Installation
In addition to its two-tier doors, the AirClean AC23238 features a removable front panel secured with four thumb screws.
This allows the entire front section to be removed when greater access is required for installing, positioning, or servicing laboratory equipment.
The removable panel is particularly useful when loading a rotary evaporator with a tall condenser, complex glassware arrangement, or other components that may be difficult to maneuver through the normal door openings.
It can also simplify cleaning and maintenance by providing more direct access to the enclosure interior.
The front panel must be properly reinstalled before the enclosure is used for procedures requiring chemical vapor containment.
External Exhaust and Chemical Vapor Containment
The AirClean AC23238 is equipped with a 4-inch exhaust duct collar for connection to an external laboratory ventilation system.
When paired with an appropriately sized blower and ductwork, the enclosure can draw room air inward through the access openings and carry chemical vapors toward the exhaust connection.
This arrangement helps prevent solvent vapors generated during rotary evaporation from accumulating around the operator or spreading into the surrounding laboratory.
Because the AC23238 is configured for external exhaust, its operation does not depend on recirculating chemical vapors through an activated carbon filtration system.
However, the enclosure does not include a blower motor. A suitable exhaust source must be selected and installed before the unit is placed into service.
Blower selection should account for the required containment airflow, duct length, elbows, static pressure, and the chemical hazards associated with the intended procedures.
Compact Design for Laboratory Benchtops
Measuring 32 inches wide, 24 inches deep, and 42 inches high, the AC23238 provides a compact alternative to larger laboratory fume hoods.
The relatively narrow width makes it suitable for laboratories where bench space is limited or where a dedicated rotary evaporation workstation must be added to an existing equipment layout.
Its 42-inch height provides additional vertical space compared with many general-purpose benchtop enclosures.
The compact configuration may also help laboratories organize rotary evaporation procedures in a designated area rather than moving equipment between different fume hoods.
Before installation, the supporting surface should be evaluated for the combined weight of the enclosure, rotary evaporator, glassware, and accessories.
Common Applications
The AirClean AC23238 is intended primarily for rotary evaporation and related solvent-handling procedures.
Typical applications include solvent removal from chemical samples, sample concentration, organic synthesis preparation, pharmaceutical research, extraction solvent recovery, chromatography sample preparation, and environmental sample processing.
The enclosure may also be appropriate for certain other laboratory instruments that require localized chemical vapor exhaust, provided the equipment fits within the enclosure and the ventilation system is suitable for the intended hazards.
The compatibility of the enclosure with any procedure should be evaluated based on the chemicals involved, quantities handled, and required containment performance.
Ideal Laboratory Environments
The AC23238 is particularly well suited for organic chemistry laboratories, pharmaceutical research and development facilities, analytical chemistry laboratories, biotechnology research facilities, environmental testing laboratories, university chemistry departments, and industrial quality control laboratories.
It may be especially useful for facilities that perform rotary evaporation regularly and want to dedicate a smaller enclosure to those procedures rather than occupying a larger conventional chemical fume hood.

Installation and Blower Requirements
Proper installation is essential for safe operation of the AC23238.
The enclosure must be connected to a suitable external exhaust system using its 4-inch duct collar. The selected blower should provide adequate airflow through the enclosure while accounting for the resistance of the complete ductwork system.
AIE does not include a blower motor with this unit. Laboratories should coordinate blower selection and ventilation design with an experienced laboratory HVAC contractor or qualified ventilation specialist.
The exhaust system must also be suitable for the chemical vapors generated during the intended rotary evaporation procedures.
After installation, airflow and containment performance should be verified with the enclosure configured for normal operation.
The unit should not be used for hazardous solvent procedures until the complete ventilation system has been evaluated.
AirClean AC23238 vs. a Conventional Chemical Fume Hood
The AirClean AC23238 and a conventional chemical fume hood both provide a means of capturing chemical vapors when connected to appropriate exhaust systems, but they are designed for different laboratory workflows.
A conventional chemical fume hood provides a larger, general-purpose workspace for chemical preparation, reactions, dispensing, and other laboratory procedures.
The AC23238 is a specialized equipment enclosure designed primarily for rotary evaporators.
Its two-tier access doors and removable front panel are particularly useful for positioning and operating evaporation equipment.
For laboratories that routinely use rotary evaporators, a dedicated enclosure can help preserve conventional fume hood space for other procedures while providing an equipment-focused workstation.
AirClean AC23238 vs. a Ductless Rotary Evaporator Enclosure
AirClean Systems also manufactures ductless rotary evaporator enclosures that use activated carbon filtration and integrated blowers to return treated air to the laboratory.
The AC23238 offered by American Instrument Exchange is configured differently. It includes a 4-inch exhaust duct collar and requires an external blower.
This distinction is important when planning installation.
A ductless enclosure may be appropriate for selected chemical applications when the installed filtration media is compatible with the solvents being handled.
An externally exhausted enclosure such as the AC23238 can be preferable where building ventilation is available or where the chemical hazards make recirculating filtration unsuitable.
The correct system should be selected based on the laboratory's chemical inventory, ventilation infrastructure, and operating requirements.
Refurbishment and Testing
This AirClean Systems AC23238 is used and reconditioned by American Instrument Exchange.
Our technicians inspect the enclosure's structural condition, access doors, removable front panel, exhaust connection, and other applicable components. The unit is cleaned and prepared for shipment following the refurbishment process.
Because the AC23238 requires an external exhaust source, final airflow performance cannot be established independently of the installed ventilation system.
Appropriate airflow and containment testing should therefore be completed after the enclosure is connected to the laboratory's selected blower and ductwork.
Shipping and Laboratory Setup
The compact dimensions of the AC23238 make it a practical option for laboratories with limited space.
Before purchase, laboratories should verify available bench space, overhead clearance, rotary evaporator dimensions, and access to the required exhaust connection.
The enclosure should be installed on a stable supporting surface capable of accommodating the weight of the enclosure and the equipment placed inside it.
American Instrument Exchange can provide additional information and photographs of the individual unit to help customers evaluate compatibility with their laboratory equipment.
