Mestra 18 litre stainless steel plaster trap for dental laboratory
The Mestra 18 litre stainless steel plaster trap is designed to manage wastewater loaded with plaster, mineral residues and particles generated by wet model trimmer work in dental laboratories.
Thanks to its 3 sedimentation compartments, it allows progressive separation of sludge in order to protect pipework, limit the risk of blockages and improve laboratory effluent management.
Its stainless steel tank and transparent lid provide excellent resistance to moisture while making it easier to visually check the filling level.
Capacity
18 litres
Separation
3 internal compartments
Connection
Standard Ø 40 mm PVC
Installation
Under dental laboratory sink
Why install an under-sink plaster trap in a dental laboratory?
Model trimming, plaster rinsing and instrument cleaning operations generate solid particles every day that can accumulate inside the drainage system.
Without a suitable separation system, these residues can cause slower drainage, progressive clogging and increased maintenance interventions.
The Mestra 18 L stainless steel plaster trap retains heavy particles before they enter the drainage network, thanks to a progressive water path through several sedimentation compartments.
This solution helps provide long-term protection for the installation and simplifies wastewater management in dental laboratories.
Why does plaster sludge foul drainage systems?
Plaster, pumice, investment material and ceramic particles are often heavy and mineral-based. When carried by water, they can settle in the lower areas of the pipework as the flow slows down.
- Progressive build-up of solid deposits.
- Slower drainage flow.
- Risk of clogging on intensive wet workstations.
- More frequent maintenance of sink traps and pipework.
- More complex management of loaded laboratory wastewater.
How do the 3 compartments improve separation?
The 3-chamber sedimentation design allows water to move progressively through the trap at a reduced speed.
The heaviest particles settle in the first compartments, while finer particles continue to settle in the following chambers.
This water path improves sludge separation before the water is discharged towards the main drain.
Benefits and applications of the Mestra stainless steel plaster trap
Benefits of the Mestra stainless steel trap
- Progressive separation through 3 compartments.
- Professional stainless steel tank resistant to moisture.
- Transparent lid for quick visual inspection.
- Under-sink installation, discreet and accessible.
- Standard Ø 40 mm connection.
- Simplified maintenance thanks to accessible compartments.
- Effective protection for drainage lines.
- Reduced risk of clogging.
Applications in dental laboratories
- Wet model trimmer stations.
- Dental model rinsing areas.
- Cleaning of technical instruments.
- Management of wastewater loaded with plaster.
- Fixed prosthodontic and implant work.
- CAD/CAM laboratories using plaster models.
- Multi-workstation laboratories with high water flow.
The 18 litre volume offers a good balance between separation capacity, compact footprint and ease of maintenance.
Under-sink installation and Ø 40 mm connection
The standard Ø 40 mm PVC connection makes integration easier on most installations used in dental laboratories.
Under-sink positioning preserves the workspace while keeping simple access for inspection and maintenance operations.
For comfortable maintenance, it is recommended to keep enough clearance around the trap to allow the lid to be opened and the internal partitions to be removed.
- Designed for under-sink installation.
- Standard Ø 40 mm PVC connection.
- Lid access must be maintained.
- Visual inspection made easier by the transparent lid.
Maintenance of the plaster trap
Maintenance frequency depends directly on the volume of plaster processed in the laboratory.
- Regularly check the level of deposits.
- Remove sludge before saturation.
- Rinse the compartments periodically.
- Check that the drains flow correctly.
- Use protective gloves during maintenance operations.
Regular use of a flocculant can also improve the agglomeration of fine particles and optimise sedimentation.
Why choose a stainless steel plaster trap?
Stainless steel offers excellent resistance to the permanent moisture found in dental laboratory wet workstations.
Unlike some plastic tanks, stainless steel withstands frequent cleaning, temperature variations and the mechanical demands of intensive professional use.
This robustness provides a long service life while maintaining excellent structural stability.
A solution suited to modern laboratories
Dental laboratories that work daily with dental plaster, implant models, precision dies or CAD/CAM workflows generate significant volumes of solid particles.
The Mestra stainless steel plaster trap is a professional solution that helps protect the drainage system while simplifying maintenance operations.
Its three-chamber design progressively improves sludge separation before clarified water is discharged.
Optimising sedimentation with a suitable flocculant
A flocculant helps group fine suspended particles together so they settle at the bottom of the trap. This solution can be useful when the laboratory generates a large amount of fine plaster, mineral sludge or very light matter.
Complementary products such as GipEx Tabs or Dentafloc can be used to improve sedimentation according to the needs of the wet workstation.

FAQ – Mestra 18 litre stainless steel plaster trap
Why use a plaster trap in a dental laboratory?
Plaster work generates many solid particles that can progressively block drainage lines.
A plaster trap retains these residues before discharge in order to provide long-term protection for the laboratory sanitary installation. It helps limit sludge accumulation, reduce interventions on the drainage network and better organise the management of loaded wastewater at the wet workstation.
What are the three sedimentation compartments used for?
The three chambers allow progressive separation of plaster sludge.
The heaviest particles settle in the first compartments, while finer particles continue to settle in the following chambers. This progressive circulation improves deposit retention before the water is discharged into the drainage network.
What are the advantages of a stainless steel tank?
Stainless steel offers excellent resistance to moisture, frequent cleaning and intensive use conditions.
In a dental laboratory, stainless steel provides better structural stability and good long-term durability. It is particularly suitable for regularly used wet workstations and installations requiring periodic cleaning.
Should a flocculant be used with this plaster trap?
Using a flocculant such as GipEx Tabs or Dentafloc is not mandatory, but it can be recommended when the laboratory generates a high volume of fine particles.
These products improve the agglomeration of suspended particles and help them settle at the bottom of the trap, which can optimise sedimentation efficiency and simplify maintenance.
How often should the trap be cleaned?
The frequency depends directly on the volume of plaster processed in the laboratory.
Regular visual inspection of the sludge level helps plan maintenance before the compartments are fully saturated. It is recommended to remove deposits before they reduce the useful volume of the trap or disturb proper water flow.
Mestra stainless steel plaster trap: effective protection for laboratory drains
With its 18 litre capacity, three-compartment design and stainless steel tank, the Mestra stainless steel plaster trap is a reliable solution for managing plaster-loaded wastewater in dental laboratories.
