Labculture® Vertical Laminar Flow Cabinet
The Esco Labculture® Vertical Laminar Flow Cabinet is a clean bench which provides ULPA-filtered laminar airflow for operations requiring a particulate-free environment. Vertical Laminar Flow Cabinets offer proven protection for your samples and processes but should not be used in experiments with biohazardous materials or toxins, as they do not provide operator protection.
Vertical laminar flow offers certain tangible advantages over horizontal flow cabinets (which may be the convention in some parts of the world), such as lower energy consumption levels (40% of conventional systems) through the use of exclusive motorized impeller technology and less airflow turbulence (especially when large objects are used in the work zone).
 Superior Product Protection
 ISO Class 4 air cleanliness within work zone as per ISO 14644.1 (equivalent to Class 10 as per US Federal Standard 209E, 10 times “cleaner” than the usual Class 100 classification on cabinets offered by the competition). All components are cleanroom compatible.
- High-quality polyester pre-filter and U15 ULPA filter(s) with a typical efficiency of 99.9997% at MPPS, 99.9998% at both 0.3 and 0.12 microns provide the best product protection in the world; typical main ULPA filter lifespan is more than 3 years depending on operating conditions and the total number of hours in usage per day.
- Integral filter metal guard on both sides prevents accidental damage to ULPA filter; endless filter gasket is permanently molded on the filter frame and will not deteriorate over time; aerosol (DOP/PAO) challenge test port included. Additional removable perforated filter diffuser is easy to clean and also protects the filter against accidental damage.
- Isocide™ antimicrobial coated cabinet structure prevents surface contamination and inhibits bacterial growth on the cabinet's external surfaces.
Control Features
-
Esco Sentinel™ Microprocessor Control with visual / audible airflow alarms ensures superior product protection and alerts the user in case of any malfunction.
-
LCD Display shows the airflow velocity for easy monitoring of work zone conditions. In addition, the control system allows for admin PIN settings to restrict access to the control menu.
Control Features
-
Stainless steel work zone will never rust, chip or generate particles and facilitates ease of cleaning.
-
Integral filter metal guard prevents accidental damage to ULPA filter; endless filter gasket is permanently molded on the filter frame and will not deteriorate over time; aerosol (DOP/PAO) challenge test port included.
-
Permanently lubricated direct drive centrifugal blower(s) - energy efficient external rotor motor type design reduces operating costs and compensates automatically for filter loading over most of the filter's lifespan.
-
Designed to meet the safety requirements of IEC 61010-1 / EN 61010-1 / UL 61010A-1 / CSA C22.2 No. 1010.1-92. Components are UL listed / recognized.
-
Built-in solid state variable speed controller(s) (infinitely adjustable from zero to the maximum setting), with built-in RFI and noise filters, is superior to conventional "step" controllers.
-
Industry-exclusive secondary isolated negative pressure filter seals and Autopurge™ slots at the back of work zone deliver enhanced product and cross-contamination protection.
Vertical Laminar Flow Cabinet Operating Principles
-
Room air is taken in from the top of the cabinet through a disposable pre-filter with 85% arrestance; this serves to trap larger particles and increase the life of the main filter.
-
Air is forced evenly across the ULPA filter(s); the result is a stream of clean laminar air within the work zone of the cabinet; this dilutes and flushes all airborne contaminants from the interior.
-
A nominal filter face velocity of 0.475 m/s or 94 fpm ensures that there is a sufficient number of air changes within the enclosed area of the cabinet in order to maintain cleanliness.
-
The purified air travels across the working zone of the cabinet in a vertical, unidirectional stream and leaves the main work chamber across the entire open front of the cabinet.
