Mestra 70 litre plaster trap for dental laboratory
The Mestra 70 L plaster trap is designed for dental laboratories that need to protect their drainage lines effectively against plaster residues, sludge and sediments generated during daily work.
Installed under the sink, this large-capacity model retains heavy materials before they enter the drainage system. It helps limit blockages, reduce maintenance operations and organise a cleaner wash station.

Large-capacity plaster trap for plaster-loaded wastewater
In a dental laboratory, rinsing water regularly carries dental plaster residues, fine sludge, heavy particles and deposits from the cleaning of bowls, models, bases or laboratory accessories.
The Mestra 70 litre plaster trap retains these materials before they enter the drainage system. It helps preserve pipework, limit drain-clearing interventions and maintain a better organised washing area.
Its 70 litre capacity makes it suitable for laboratories that use their rinsing station intensively, especially around plaster work, models and laboratory accessories.
The problem encountered in dental laboratories
Dental plaster does not disappear in water. It gradually settles in pipework, hardens, traps other particles and can cause slower drainage.
Over time, these deposits can lead to odours, loss of flow at the rinsing station or costly blockages to remove.
- Progressive accumulation of plaster sludge.
- Risk of blockages in the drainage system.
- More frequent drain maintenance.
- Less clean and less efficient wash station.
The solution provided by the Mestra 70 L plaster trap
Thanks to its large capacity, the trap gives heavy particles time to settle in the tank before the water flows back towards the drain.
This simple separation by gravity protects the pipework, improves rinsing station maintenance and provides more autonomy than a compact plaster trap.
- Large sedimentation volume.
- Retention of heavy sediments.
- Easier maintenance thanks to castors.
- Drain tube provided for emptying the trap.
Professional applications at the laboratory wash station
The Mestra 70 L plaster trap is intended for laboratories that regularly produce wastewater loaded with plaster, sediments and mineral sludge.
Rinsing plaster bowls and accessories
The trap is suitable for cleaning mixing bowls, spatulas, accessories and tools used with dental plaster and stone.
Protection of under-sink drainage lines
It limits the direct passage of sediments into the laboratory wastewater system, reducing the risk of progressive pipe fouling.
Management of sludge and heavy particles
Sludge, deposits and residues from daily work are retained in the tank so they can be removed during maintenance operations.
Organisation of an intensive rinsing station
With its 70 litre capacity, this model is suitable for workshops requiring a more comfortable solution than a small plaster trap.
Benefits and installation of the 70 litre plaster trap
Benefits for the dental technician
- Reduced risk of blockages caused by plaster deposits.
- Long-term protection of the laboratory drainage system.
- High autonomy thanks to the 70 litre capacity.
- Simpler maintenance with drain tube, castors and internal access.
- Cleaner and better organised wash station.
- Solution suitable for laboratories with sustained activity.
Under-sink installation
- Plan installation under the sink on a flat, stable surface.
- Remove the sink trap or any element obstructing direct drainage.
- Connect the supplied Ø 50 mm outlet.
- Connect the trap drain tube to the laboratory’s main drainage system.
- Check the available under-sink space before installation.
- Use a plumber if the configuration requires it.
Maintenance of the 70 litre plaster trap
The trap should be cleaned when sediments reach approximately half of the container. Even if this level has not been reached, a full cleaning every 2 to 3 months is recommended depending on intensity of use.
Regular maintenance helps preserve good sedimentation efficiency, limit odours and make it easier to remove deposits before they become too compact.
Recommended cleaning procedure
- Remove the drain tube from its fixing.
- Place the end of the tube into a bucket or suitable container.
- Pull the trap out from under the sink using the integrated castors.
- Unscrew the tube fixing to release the drain.
- Empty the water into a suitable container.
- Remove the grid and lid.
- Remove the plaster deposits at the bottom of the trap with a scoop or by emptying the container into a suitable waste bin.
- If possible, clean outdoors with a garden hose or low-pressure water jet.
- Reinstall the trap by following the steps in reverse order.
To improve sedimentation, the use of a flocculant for plaster traps is recommended.
Why use a flocculant?
A flocculant helps fine particles agglomerate to form deposits that are easier to retain in the tank.
In a heavily used laboratory, it can improve sedimentation quality and simplify maintenance, especially when the wash station receives a high volume of plaster residue.
Good practices at the wash station
- Avoid emptying large quantities of plaster directly into the sink.
- Regularly check the sediment level inside the trap.
- Clean before the container is fully saturated.
- Rinse removable components during maintenance.
- Follow internal plaster sludge management procedures.

FAQ – Mestra 70 L plaster trap
What is a plaster trap used for in a dental laboratory?
A plaster trap is used to retain heavy residues before they enter the drainage system.
In a dental laboratory, it is particularly useful for collecting plaster remains, rinsing sludge and particles generated when cleaning models, bowls and accessories. Without sedimentation, these materials can gradually settle in the drainage network, harden and cause blockages.
Why choose a 70 litre capacity?
The 70 litre capacity is useful for laboratories that use their rinsing station heavily.
It provides more sedimentation volume than a small trap and helps absorb loaded wastewater produced throughout the day. This format is suitable for structures that regularly handle dental plaster, clean many models or want to extend the interval between maintenance operations.
When should the plaster trap be cleaned?
The trap should be cleaned when sediments reach approximately half of the container.
Even if the maximum level has not been reached, a full cleaning every 2 to 3 months is recommended depending on intensity of use. Regular maintenance also limits odours and makes it easier to remove deposits before they become too compact.
Is the Mestra 70 L trap easy to move for maintenance?
Yes, this model is equipped with integrated castors that make it easier to move during draining and cleaning.
This is important because a large-capacity trap can become difficult to handle when loaded with water and sediments. The castors make it easier to pull the trap out from under the sink, access the tank and work in a more practical area.
Should a flocculant be used with this plaster trap?
Using a flocculant is not always mandatory, but it is strongly recommended when the wash station receives a large amount of plaster residue.
The flocculant helps fine particles agglomerate and encourages them to settle inside the tank. In a heavily used laboratory, this can improve sedimentation quality and make maintenance easier. GIPEX Tabs are a complementary solution suited to this type of use.
A large-capacity solution to protect laboratory drains
The Mestra 70 litre plaster trap is a professional solution for dental laboratories that regularly generate wastewater loaded with plaster, sludge and sediments.
Its large capacity, integrated castors, drain tube and Ø 50 mm outlet make maintenance easier while improving protection of the drainage network.
For an intensive wash station or a laboratory looking for more autonomy than a compact trap, the Mestra 70 L plaster trap offers a robust, practical solution suited to daily use.
