Erlab secure weighing stations. Total safety and peace of mind for all users.
La solution idéale pour les opérations de pesage dangereuses.
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.

Qu'est-ce qu'un cabinet de pesage de poudres ?
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.
Une cabine de pesage de poudres renvoie l'air dans le laboratoire après l'avoir filtré. Une hotte à conduits renvoie l'air à l'extérieur à l'aide d'un système CVC. Lors de la manipulation de poudres, la hotte à conduits présente deux problèmes :
- Il est relié à l'extérieur, de sorte que le débit variable du vent influencera le débit de l'air dans l'armoire. Il en résulte des fluctuations de pression qui peuvent influencer les résultats de la pesée.
- Les poudres sont plus lourdes que l'air. Dans les virages du système HVAC, les poudres ont tendance à rester derrière en raison de la force centrifuge.
Ces deux facteurs font de la cabine de pesée une solution bien meilleure pour le pesage des poudres.
Les filtres HEPA H14 sont des filtres à particules. Les particules peuvent être des poussières ou des microgouttelettes. La plupart des produits chimiques liquides présentent une évaporation de molécules qui ne sont pas capturées par les filtres HEPA. Malgré cela, il existe une solution. Des filtres à charbon peuvent être montés sur les filtres HEPA. Les filtres à charbon sont remplis de charbon actif contenant des revêtements chimiques. Ces revêtements peuvent capturer les molécules en utilisant un processus appelé 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.
