FormolSafe® – Automated Formalin Dispensing Device

Secure Dosage and Filling of Formalin for Operating Theaters and Pathological Anatomy Laboratories!





Formaldehyde recognized as a category 1B carcinogen based on European regulation N605/2014. Work with formalin concerns operators in the operating room, pathological anatomy laboratories and sample transport.



Perfectly preserve biological samples to allow correct diagnosis and all subsequent biomolecular investigations.

Protect operators from exposure to formalin vapors



STAHLMED LABORATORY SYSTEMS has acquired know-how and considerable experience over the years in the field of formalin security, to provide a complete solution guaranteeing precise diagnosis, quality and optimal safety for operators, from the pre-analytical phase in the post-analytical phase



§ Safe filling of buckets with 4% buffered formalin, inside a completely closed and ventilated enclosure, guaranteeing the containment of vapors for the safety of users

§ Dispensing of formaldehyde disabled if the motorized front window of the work chamber is not closed

§ Lighting of the working area for the visual control of the filling level of the buckets

§ Filling canister located in the low ventilated cupboard with quick connector to avoid contact with formalin for the safety of users

§ Large touch screen displaying all Formolsafe parameters (ventilation, filtration, pump activation, alarms, etc.)

§ No specific consumables required

§ Filtration of formalin vapors before discharge to the outside (ED6185 INRS)


§ The FORMOLSAFE meets the needs of operating theaters that want a secure system for filling buckets containing samples with 4% buffered formalin, guaranteeing user safety.

§ The FORMOLSAFE makes it possible to fill rigid, standard buckets of all sizes, without the operator being subjected to fumes or contact with the fixer. The volume of formalin dispensed is controlled by the user.

§ To launch a filling program, simply place the container containing the sample inside the FORMOLSAFE enclosure. Once the motorized sliding window is in the closed position, the formalin dispensing pump activates and the dosing of the fixative can begin in complete safety.

§ The FORMOLSAFE uses standard containers available on the market or closed circuit cubitainers with a capacity of 10 or 20 liters.



– Put the biological sample in the bucket adapted to its size

– Place the buckets in the work enclosure under the tap

– Closing of the motorized sliding window and activation of the formalin pump

– Press the pedal to start the formalin dosage inside the completely closed and ventilated enclosure

– Volume control thanks to the lighting of the work area

– Opening of the motorized sliding window with increased ventilation in order to maintain a minimum flow of 0.5 m/s at the level of the opening.

– Close the bucket with its lid

– Stick the tracking label on the bucket

– Place the bucket in a ventilated cabinet awaiting collection by the pathological anatomy laboratory
