Erlab secure weighing stations. Total safety and peace of mind for all users.
The ideal solution for hazardous weighing operations.
ERLAB secure weighing station guarantees an outstanding level of safety for users. It provides the required stability as well as the level of accuracy (up to 0,01 mg) required when weighing in the laboratory. It is the ideal solution for hazardous operations that require a confined environment, eliminating any risk of personnel being exposed to toxic products. Containment and filtration guaranteed by their compliance with the AFNOR NF X15-211 standard. The exclusive eValiQuest service assesses the risk of your operations and reduces any risks associated with your system.
The safest weighing stations are also the least expensive.
This device makes significant savings on installation and operation. It eliminates energy consumption associated with renewing the laboratory’s air (air supply/extraction, filtration, dehumidification, and air conditioning). With an energy consumption between 70 W and 191 W, operational costs are extremely low.

What is a powder weighing cabinet?
A powder weighing cabinet or balance enclosure is a type of cabinet that protects the operator from the powder products being manipulated inside. Often the application is weighing. The ventilator pulls the air from the cabinet and directs it through a HEPA H14 filter that captures the particles.
A powder weighing cabinet sends the air back into the lab after filtering it. A ducted fume hood sends the air outside using an HVAC system. When manipulating powders, the ducted fume hood comes with 2 problems:
- It is connected to the outside, so the variable flow rate of the wind will influence the flow rate of the air in the cabinet. This means pressure fluctuations that can influence the results of the weighing.
- Powders are heavier than air. In the turns of the HVAC system, powders tend to stay behind due to the centrifugal force.
These 2 factors make the powder cabinet a much better solution for weighing powders.
HEPA H14 filters are particle filters. Particles can be dust or microdroplets. Most liquid chemicals have evaporation of molecules that are not captured by the HEPA filters. Despite this, there is a solution. Carbon filters can be mounted on top of the HEPA filters. Carbon filters are filled with active charcoal that contains chemical coatings. These coatings can capture molecules by using a process called adsorption
When products get more dangerous, there are 2 considerations for the cabinet choice:
The filter replacement procedure: during filter replacement, it is possible that particles get released from the filters and get airborne again. So for the protection of the service engineer doing the replacement and the staff working in the lab, a safe filter replacement procedure like BIBO (Bag-In-Bag-Out) need to be considered. If BIBO is required, Analis can offer the Esco Ventilated Balance Enclosure.

Open versus closed systems. Open systems are more convenient to work with and come with a lower investment cost. Closed systems provide a better containment due to the physical separation between the users and the product. If a closed system is required, Analis can offer Esco Healthcare Platform Isolators.
