AirClean Systems launches new Patriot ductless fume hoods.


AirClean Systems, the North American leader in ductless containment since 1992, announces the introduction of its newest product line: Patriot Ductless Fume Hoods. Patriot ductless hoods incorporate much of the advanced technology of AirClean’s Independence fume hood with the cost effective backbone of AirClean’s AC4000 folding and sliding-sash ductless fume hoods.

Patriot ductless fume hoods feature the easy-to-use AirSafe™ NXT automatic safety controller for added operator safety. This color touchscreen controller automatically increases or decreases blower speed to maintain the user’s pre-set face velocity, ensuring airflow is within standard operating parameters. The current face velocity is displayed at all times. AirSafe NXT also monitors the bonded carbon filtration bed, alerting the user audibly and visually should filter saturation occur. Patriot features a unique ‘application confirmation’ sequence that is required with every use of the hood. AirSafe NXT displays the approved chemical class for the hood, and waits for a confirmation from the user before allowing the hood to be used.

In addition to safety features, AirSafe NXT also provides a multi-language and multi-unit capability not found in most ductless hoods. With the press of a button, users can switch the controller language between English, Spanish, French and German. Airflow can be displayed in both linear feet per minute (LFM) and meters per second (m/s).

Patriot ductless hoods eliminate the need for costly installation, ductwork and over-built HVAC systems associated with traditional fume hood use within the laboratory. An on-board energy meter, accessed via AirSafe TOUCH, displays the real-time and life-time energy use of the hood.

AirClean Systems’ unique bonded carbon filtration is standard on all Patriot ductless fume hoods. For added application breadth and capacity, Silconazyne™ filtration is also available for Patriot.

Patriot’s rolled-entry design combined with AirZone™ baffling provides laminar flow within the cabinet, preventing eddy currents and keeping fumes or particulate from escaping the hood. Seamless, thermally welded polypropylene construction means the Patriot will never rust, providing years of service life. All electronics and blowers are post-filter, so they are never exposed to chemicals used in the hood.

All AirClean Systems ductless fume hoods are made in the USA and ship fully assembled, requiring very minimal installation. Simply place on a cabinet, stand or bench top and plug into a standard 110V or 220V outlet. The Patriot ductless fume hood can be installed and used within minutes of being removed from its shipping container.

Patriot ductless fume hoods are now available. Folding sash and sliding sash models are initially available in 48” and 72” widths.

Microfluidic bead-based multienzyme-nanoparticle amplification for detection of circulating tumor cells in the blood using quantum dots labels   Original Research Article

Available online 6 April 2013
He Zhang, Xin Fu, Jiayi Hu, Zhenjun Zhu

Graphical abstract

A microfluidic beads-based nucleic acid sensor for sensitive detection of circulating tumor cells (CTCs) in the blood using multienzyme-nanoparticle amplification and quantum dots labels was developed. The chip-based CTCs analysis could detect reverse transcription-polymerase chain reaction (RT-PCR) products of tumor cell as low as 1 tumor cell (e.g. CEA expressing cell) in 1mL blood sample. This microfluidic beads-based nucleic acid sensor is a promising platform for disease-related nucleic acid molecules at the lowest level at their earliest incidence.
