Why install an under-sink plaster trap in a dental laboratory?
In a dental laboratory, wet workstations generate wastewater every day that may contain plaster, pumice, mineral particles, ceramic dust, dental investment material residues and sludge from finishing operations.
These particles do not behave like simple soluble dirt. They are often heavy, abrasive and capable of gradually settling in the pipework when water slows down or stagnates.
Without a pre-separation system, deposits can accumulate in the wet workstation drain, reduce flow rate, encourage unpleasant odours and increase maintenance interventions.
What problems can plaster, pumice and mineral sludge cause?
Heavy residues generated by daily laboratory work can gradually build up in the lower areas of the drainage system.
- Progressive slowing of water drainage.
- Accumulation of compact sludge inside the pipework.
- Risk of blockage on heavily used workstations.
- More frequent maintenance of drains and traps.
- Odours caused by stagnant deposits.
- Workstation downtime when cleaning becomes necessary.
Which workstations are most affected?
The most exposed wet workstations are those that regularly generate mineral materials suspended in water.
These problems particularly concern laboratories equipped with a wet model trimmer, bowl and spatula rinsing areas, instrument cleaning stations and spaces where mineral materials are processed daily.
The plaster trap adds a retention stage before discharge into the main drainage system.
How does the Mestra 14 L plaster trap protect the under-sink drain?
The Mestra 14 L plaster trap acts as an intermediate stage between the water point and the main drainage line. When loaded wastewater passes through the tank, its flow speed is reduced, allowing the heaviest particles to settle before the water continues its path.
The collection bag makes sludge recovery easier and limits direct contact with accumulated waste. It supports cleaner and more regular maintenance, especially in laboratories that frequently work with plaster, pumice or investment materials.
The lid with closure system allows the filling level to be checked and the condition of the trap to be inspected without complex dismantling. This design makes daily monitoring simpler.
Applications and benefits of the Mestra plaster trap in a dental laboratory
Professional applications
Protection for wet model trimmer stations
The trap helps retain part of the plaster residue generated during trimming, finishing and adjustment of models. It contributes to the management of wet model trimmer residue discharge.
Separation of rinsing wastewater
It supports the pre-treatment of plaster-loaded wastewater before discharge into the drainage system, especially after cleaning bowls, spatulas and instruments.
Retention of abrasive particles
The Mestra plaster trap is suitable for wet workstations exposed to pumice, ceramic particles, investment material, metal filings or mineral sludge.
Benefits for the laboratory
- Reduced solid deposits entering the pipework.
- Better protection and maintenance of dental wet workstations.
- Cleaner maintenance thanks to the collection bag.
- Simple visual inspection of the filling level.
- Standard Ø40 mm under-sink installation.
- Compact format suitable for technical cabinets.
- Reliable Mestra solution for dental laboratories.
- Improved organisation of wastewater management.
Ø40 mm under-sink installation and maintenance of the Mestra plaster trap
This plaster trap is designed for installation on a Ø40 mm drain outlet, generally between the sink trap and the main waste pipe. Before installation, it is important to check the available space under the cabinet, the useful height, the connection orientation and access to the lid.
The collection bag must be positioned correctly in order to retain sludge and heavy residues. It is recommended to replace it before saturation, ideally when it reaches around 70% of its filling capacity.
Periodic rinsing of the tank with lukewarm water helps reduce odours, prevent overly compact deposits and maintain consistent separation over time.
For heavily used workstations, using a flocculant for plaster traps can improve the sedimentation of fine particles.
How to choose a 14 L plaster trap for a dental wet workstation?
The choice depends on the volume of loaded wastewater, the number of connected workstations, the frequency of use and the space available under the sink.
A 14 litre plaster trap is often a good compromise for a dental laboratory that wants to protect a drain without installing a very large tank.
For an individual workstation, a rinsing area or a regularly used wet model trimmer station, this format provides sufficient capacity while remaining compact.
When should you consider a flocculant or a larger capacity?
When the laboratory generates a large amount of fine particles, adding a flocculant can help group suspended matter together and improve its deposit inside the trap.
For several connected rinsing points or very intensive activity, a larger-capacity model can help extend the interval between maintenance operations.
The Mestra 14 L plaster trap remains a relevant solution for securing a standard wet workstation with a simple installation.
Checking the collection bag
The collection bag makes maintenance easier and allows accumulated sludge to be recovered more cleanly.
- Check the filling level regularly.
- Replace the bag before complete saturation.
- Avoid allowing sludge to dry inside the trap.
- Rinse the tank during maintenance operations.
Organisation of the wet workstation
Good workstation organisation limits residue build-up in the drainage system and simplifies daily maintenance.
- Avoid emptying large quantities of plaster directly into the sink.
- Clean instruments before the trap becomes saturated.
- Use a flocculant if fine particles remain suspended.
- Follow internal waste management procedures.

FAQ – Mestra 14 litre plaster trap
Why install a plaster trap under a dental laboratory sink?
Wastewater produced during laboratory procedures often contains plaster, pumice, ceramic residues or mineral particles that can gradually settle in the pipework.
A plaster trap helps retain part of these materials before they reach the drainage system. This step reduces the accumulation of heavy deposits and makes laboratory installation maintenance easier.
Is the Mestra 14 litre plaster trap suitable for a wet model trimmer station?
Yes, this model is particularly suitable for wet model trimmer stations, rinsing areas and instrument cleaning spaces.
Its 14 litre capacity offers a good compromise between reduced footprint and retention capacity for a standard dental laboratory workstation. For several connected workstations or very intensive activity, a larger capacity may be considered.
How often should the collection bag be cleaned or replaced?
The frequency depends directly on the volume of residue generated by the laboratory and the number of daily uses of the wet workstation.
Regular visual inspection helps anticipate replacement before saturation. It is advisable to act when the bag reaches around 70% of its capacity in order to maintain good separation efficiency and avoid excessive sludge accumulation.
Is flocculant required with this plaster trap?
No, the trap works naturally through gravity separation. The heaviest particles settle spontaneously inside the tank.
However, using a flocculant remains useful in laboratories producing a high volume of fine particles, as it improves their agglomeration and sedimentation. GipEx Tabs flocculant can be used as a complementary product according to the needs of the wet workstation.
What is the difference between a 14 litre plaster trap and a larger model?
A larger-capacity model generally allows longer intervals between maintenance operations and stores more sludge before cleaning.
The Mestra 14 litre plaster trap focuses on compactness, simple under-sink installation and an excellent footprint-to-capacity ratio for a standard workstation. It is suitable for laboratories that want to protect a specific drain without installing a bulky tank.
Can this plaster trap be used with several workstations?
This model is mainly intended to protect one specific drain or wet workstation.
For several workstations connected at the same time or for intensive activity, it may be appropriate to consider a larger capacity in order to maintain comfortable maintenance intervals. The Mestra 14 litre plaster trap remains a suitable solution for an individual workstation, a rinsing area or a standard wet model trimmer station.
