PROCESS
Handling and manipulation of API (Active Pharmaceutical Ingredients) and other toxic materials where personnel protection is required.
CONTAINMENT
Heavily dependent on potency and quantity of the toxic material being worked with, this unit can contain a wide variety of OEL levels. Consult FSI about your application.
EQUIPMENT
The ETA Series can provide containment for many applications and equipment, including balances, microscopes, particle analysis, and many more.




FEATURES & BENEFITS
BAG-IN / BAG-OUT (BIBO) TECHNOLOGY
Flow Sciences’ Top Mount Safety Enclosure with Bag-in / Bag-out (BIBO) Filtration is engineered to provide a safe, stable working environment in laboratory settings. The BIBO filter is designed for safe disposal and replacement of HEPA filter by a certified technician. Watch the video:

CLEANABLE FROM FACE TO FILTER
Unlike Alternative Technology, Flow Sciences Units Can Be CLEANED FROM FACE OPENING TO HEPA FILTER
Leaving NO Uncleanable Areas and Preventing Cross Contamination

SAFETY
The Top Mount series provides containment for various benchtop / scale up and nanotechnology applications. FSI engineering controls are built in to prevent loss of containment. Third Party testing has proven containment on these units to below 1 μg/m3 based on process and quantity.
DESIGN
This unit is able to effectively contain using airfoils and plenums to create laminar airflow across the work surface and reduce eddies and turbulence.The top mounted exhaust system with dual 4” HEPA filters or carbon filters can be recirculated into the lab or sent directly to house exhaust.
VELOCITY ALARM
This series includes a face velocity alarm that comes standard on all units, either integrated into the fan power or separate. A visual and audible alarm alerts the operator when airflow is compromised. The air velocity is measured at the face opening to be the most accurate.
DESIGN
This unit is able to effectively contain using airfoils and plenums to create laminar airflow across the work surface and reduce eddies and turbulence.The top mounted exhaust system with dual 4” HEPA filters or carbon filters can be recirculated into the lab or sent directly to house exhaust.
HEPA FILTRATION
The Glovebox Workstation system is equipped with a 4″ HEPA filter inlet and primary and secondary 4” HEPA outlet filters that can be recirculated into the lab or sent directly to house exhaust.
LED LIGHT
This enclosure features an optional internal white LED light for improved visibility inside of the enclosure that provides direct light onto the application. Ask your representative to add the LED light to your Vented Balance Enclosure. Also available in Amber LED through customization.
VIBRATION ISOLATION
Flow Sciences engineering controls provide vibration isolation to ensure 6-7 place balance stability and reproducibility of samples.
DUAL HEPA FILTER TECHNOLOGY
The Dual HEPA Series ETA systems have two 4″ Pleated HEPA filters, one primary and one secondary (redundant). The non-loading secondary HEPA filter prevents any contaminants that might migrate upstream during Bag-in/Bag-out disposal from coming in contact with the fan unit and being discharged to house exhaust or re-circulating into the room.

STANDARD OPTIONS
STANDARD SIZES
The ETA Series is available in 3, 4, 5, 6, and 8 foot standard width options. Other options include 24″ or 30” depth with 24” or 27″ internal height. Customization available.

This series comes standard with clear acrylic construction with white acrylic rear wall (ETA Series), or all clear acrylic for increased visibility (ETC Series)
EXHAUST OPTIONS
Many exhaust options and configurations are available for both single and dual HEPA models. See below for more information.
FILTRATION
Bag-In/Bag-Out (BIBO) Dual 4″ Pleated HEPA Filtration or Single HEPA filtraiton. Also, Carbon filtration for organics, amines, aldehydes, or acids is available in conjunction with the HEPA filtration. ULPA filtration is available upon request.
ELECTRICAL OPTIONS
110V-120V 50-60HZ; 220V-240V 50-60HZ with Integrated Alarm and Separate Alarm
BASE (TOP)
The base is dished for powder or liquid spills constructed of thick phenolic resin for durability.
