Features and Benefits

Learn More: Common Hood Applications

Adapting Common Laboratory Hoods for Specialty Purposes

Most hoods designed for specialty applications are derived from standard laboratory configurations (e.g. laminar flow and fume hoods) adapted to specific requirements.


PCR Workstations

Polymerase chain reaction (PCR) is a common technique used in molecular biology to exponentially amplify a target region of DNA or RNA. PCR can turn a single piece of DNA into more than a million pieces in the matter of hours. Unfortunately, a single piece of contaminating DNA can also be amplified, making it extremely important that researchers work within a sterilized area that prevents cross contamination of samples.

PCR workstations were designed to minimize this problem. Adapted from laminar flow hoods, PCR workstations provide HEPA-filtered, sterile air within the hood. These hoods are outfitted with UV-C germicidal lights to disinfect the work surface when the hood is not in use. The lights are also placed on a timer to reduce the risk of UV exposure. In addition to its germicidal properties, UV-C light also causes breaks in strands of DNA that prevent the DNA from being amplified during PCR. Therefore, the UV-C light also serves to prevent carry-over contamination from previous experiments.

Explosion-Proof Hoods

Explosion-proof hoods are a variation of either the laminar flow or exhaust fume hood, designed for work involving potentially flammable material. The conventional motor of the hood is replaced by an NEC Division I-rated non-sparking motor, mounted in a cast-iron, explosion-proof housing. In addition, the hood features an explosion-proof light, and all wiring is encased in filled rigid conduit.

These hoods bear an NEC sub-rating: Division I, Class 1 indicates suitability for use where flammable materials are generally present, and Division I, Class 2 indicates suitability for use when such materials are only intermittently present.

Balance Enclosures

Weighing dry powder chemicals is a routine laboratory task. Weighing procedures frequently result in some of the powder becoming airborne irritants – and potentially toxic threats – to lab personnel. Balance enclosures minimize this danger.

They are essentially ductless fume hoods with a few minor modifications. These negative pressure enclosures direct air from outside the hood through a HEPA filtration system before it is returned to the room. The HEPA filtration system is 99.99% effective in removing particles as small as 0.3 microns in diameter from the air, virtually eliminating the risk of personnel exposure. The front sash of the balance enclosure opens upward, allowing easy transfer of balances into and out of the enclosure.

Nanoparticle Enclosures

These enclosures are essentially balance enclosures that use an ULPA filter, which is 99.995% efficient in removing particles as small as 0.12 microns, to contain the much smaller particles generated during nanomaterial processing.

Products Compliant With Your ISO Rating

Provide Terra with your desired ISO rating. We will tailor the product to meet your rating and supply a certificate of compliance appended to your invoice, to be included in your compliance package. All certificates are archived in Terra's system for quick retrieval.

Long Running FFU Motors

Terra’s filter fan unit motors are rated for 5 years of continuous, 24/7 operation, if the HEPA filters are consistently replaced. To accurately monitor your HEPA filter’s saturation levels, purchase Terra’s audible and visual filter replacement alarm system.

Recessed Lighting and Optional UV-C Sterilization

Included recessed light fixture simplifies cleaning and minimizes airflow disruptions (shown next to optional UV sterilization bulb).

Touchscreen Control Panel

PLC control panel provides control of fan speed, lights, and motorized shield; digital gauge monitors backpressure and issues alerts when filter(s) need replacement

Room-Side Replaceable HEPA Filter

To simplify filter replacement, HEPA filters can be removed and replaced while the FFU remains installed; the gel-sealed filter seats securely against the "knife-edge" on the blower housing to form a tight seal.

Vertical Flow of HEPA-Filtered Air Meets ISO 5 Particle Requirements

Side panels and access shield optimize unidirectional flow of HEPA-filtered air; advanced baffling technology ensures uniform face velocity to meet ISO 5 particle requirements.

Motorized Access Shield

Motorized access shield, included on select models, enhances laminar flow and protects operator from chemical fumes and other environmental nuisances.

Integrated Stands Isolates Hood from Work Surface

Built-in stand with dissipative PVC side panels allows VLF Stations to be positioned over any table or processing equipment without transferring hood vibration to work surface (shown integrated with optional modular wet station).

Clean and Durable Powder Coat Finish

Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

WhisperFlow Quiet Operation Reduces Distracting Background Noise

Exposure to loud noises can lower the ability to focus on work and listen selectively, which may also lead to safety issues. Typical AC units can be annoyingly loud, measuring in the range of 70 dB (comparable to a vacuum cleaner). Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).
