Mestra 19 L Under-Sink Sedimentation Tank Ø40 for Dental Laboratories
The Mestra 19 L sedimentation tank is designed for under-sink Ø40 mm installation in dental laboratories to retain heavy residues before wastewater reaches the drainage system.
It helps reduce clogging in laboratory drain pipes, especially in wet workstations where dental plaster, pumice, filings, ceramic residues, investment material and mineral particles are regularly present.
With its 19 L capacity, collector bag and lockable lid, this Mestra tank offers more retention volume for laboratories looking for a practical and reliable wastewater protection solution.
Quick Summary
Higher capacity
A 19 L format suited to frequently used wet workstations.
Reliable sedimentation
Retains heavy particles before they enter the drainage network.
Simple maintenance
The collector bag makes sludge and waste handling easier.
Ø40 installation
Designed for standard under-sink Ø40 mm drain connections.
Why Choose a 19 L Sedimentation Tank in a Dental Laboratory?
In a dental prosthetics laboratory, rinsing water can carry dental plaster, residues of dental investment material, ceramic particles, pumice and mineral sludge.
Without a dedicated settling system, these heavy materials can gradually build up inside the drain pipes, slow down wastewater evacuation, cause blockages and increase maintenance interventions.
The Mestra 19 L sedimentation tank acts as a first mechanical barrier. Heavy particles settle inside the tank while water continues toward the drainage network.
This 19 L format is particularly useful for model trimmer stations, repeated rinsing areas, bowl and spatula cleaning, or workstations that regularly generate mineral sludge.

Enhanced Retention of Mineral Sludge
The Mestra 19 L tank is suitable for laboratories that want more retention capacity than a smaller compact model.
It helps retain plaster, investment material, ceramic, pumice and filings before they circulate inside the drainage system.
This pre-settling stage helps protect the drain network and reduce workstation downtime caused by blockages.
Clean and Accessible Maintenance
The collector bag helps concentrate sludge and heavy residues for easier removal.
The lockable lid allows filling-level checks and provides access to the tank when bag replacement is required.
For active laboratories, this configuration supports a cleaner and more regular maintenance routine.
Key Benefits of the Mestra 19 L Sedimentation Tank
- 19 litre capacity for greater comfort on regularly used wet workstations.
- Efficient sedimentation of heavy residues such as plaster, pumice, investment material, ceramic and filings.
- Under-sink Ø40 mm installation compatible with common laboratory setups.
- Collector bag included for cleaner and simpler maintenance.
- Practical visual monitoring thanks to the lockable lid.
- Mestra quality, recognised in dental laboratory equipment.
Dental Laboratory Applications
- Rinsing and washing stations in dental prosthetics laboratories.
- Retention of dental plaster, investment material, pumice, ceramic residues and mineral particles.
- Protection of drainage systems in wet finishing or equipment cleaning areas.
- Recommended for use with a model trimmer.
- Suitable for laboratories looking to secure a more heavily used wet workstation.
For applications generating large amounts of heavy material, an installation with two tanks in series may be considered to increase retention capacity.
Instructions for Use
- Install the tank on the Ø40 mm drain line between the trap and the main discharge pipe.
- Check the watertightness of the assembly.
- Make sure the collector bag is correctly positioned.
- Close the lid using the locking key.
- Replace the bag when it reaches around 70% full.
- Rinse the tank with lukewarm water to reduce odours and maintain regular operation.
Compatibility and Integration
This Mestra sedimentation tank is designed for under-sink installation on a standard Ø40 mm drain outlet.
It is suitable for laboratories that want to secure a wet workstation without complex installation, while keeping practical access for maintenance.
Before installation, check the available space under the cabinet, usable height, drain orientation and access to the lid.
Care and Maintenance
Monitoring the filling level is part of good maintenance practice.
The collector bag must be replaced before saturation in order to maintain efficient sedimentation and avoid internal overflow.
Periodic tank cleaning helps reduce odours, prevent compact sludge deposits and extend the service life of the equipment.
How to Choose a Sedimentation Tank?
The right choice depends on the volume of loaded wastewater, the number of connected workstations and the actual space available under the sink.
A 19 L sedimentation tank is a very good compromise for a laboratory that wants more retention capacity than a smaller model while keeping a compact under-sink installation.
For intensive rinsing, repeated use or an environment regularly producing mineral sludge, this format can help space out maintenance operations.
This system is especially useful when using a model trimmer.
Laboratory Tip
In case of intensive use with a large amount of fine particles, adding a flocculant for sedimentation tanks can help bind suspended matter and improve sedimentation.
This solution can be useful to optimise maintenance on heavily used workstations.
It can also make sludge management easier when the workstation receives a lot of fine dust or plaster residues.

FAQ — Mestra 19 L Sedimentation Tank
Does the Mestra 19 L sedimentation tank require regular maintenance?
Yes, regular monitoring is recommended to maintain efficient sedimentation.
The collector bag should be replaced when it reaches around 70% full to avoid saturation and maintain proper water circulation.
Why choose the 19 L format rather than 14 L?
The 19 litre format provides higher retention capacity, which is useful for more frequently used wet workstations or laboratories that want to space out maintenance operations.
It remains suitable for under-sink installation while providing greater comfort for mineral sludge management.
Can it be used for ceramic or investment residues?
Yes, this tank is designed to retain various heavy laboratory residues, including plaster, pumice, some investment residues, ceramic particles and mineral sludge.
For very intensive use, an additional filtration solution or a series installation may be considered.
How is the tank installed under the sink?
It is installed on a Ø40 mm drain pipe, between the trap and the main discharge line.
Before installation, check the available space, access to the lid and the orientation of the drain according to the cabinet configuration.
Can a flocculant be used with this sedimentation tank?
Yes, using a flocculant for sedimentation tanks can help bind fine particles and improve sedimentation.
This can be useful on highly active workstations producing large quantities of plaster dust, mineral sludge or fine suspended matter.
Is this model suitable for a model trimmer station?
Yes, this type of tank is particularly relevant for a model trimmer station or any wet area that regularly generates mineral sludge.
It helps retain heavy particles before they reach the dental laboratory drainage system.
Why choose a Mestra tank?
Mestra is a recognised brand in dental laboratory equipment, with solutions designed for daily professional use.
The Mestra 19 L tank combines retention capacity, easy maintenance, visual monitoring and under-sink Ø40 mm compatibility.
