Mestra dental plaster traps for prosthetic laboratories

The Mestra plaster trap collection brings together solutions designed for the management of wastewater in dental laboratories. These traps retain heavy residues from plaster, pumice, polishing, grinding and cleaning of prosthetic work.

A dental laboratory plaster trap protects drainage lines by slowing down the water flow. Solid particles gradually settle inside the trap before the clarified water is discharged.

Depending on the laboratory’s activity level, Mestra models can equip an individual workstation, an under-sink installation or a more intensive working area.

Why use a plaster trap in a dental laboratory?

Rinsing water in a laboratory can contain plaster, resin, pumice, sludge and abrasive particles. Without a suitable system, these deposits can accumulate inside pipework and make maintenance more difficult.

The plaster trap works by gravity separation. The heaviest materials settle at the bottom of the trap, while clearer water continues towards the drain.

This simple solution improves workstation cleanliness and helps organise the management of loaded wastewater more effectively.

How a plaster trap works

The operation of a plaster trap for dental laboratories is based on gravity separation. Wastewater loaded with plaster, sludge or solid particles slows down inside several compartments.

Heavy residues settle at the bottom of the trap. The less loaded water then continues towards the drain. This principle limits the direct passage of solid matter into the pipework.

Regular monitoring of the sludge level helps maintain effective separation and reduce the risk of fouling.

Benefits of a Mestra plaster trap

Protection for drainage lines

The trap retains heavy particles before discharge and reduces the accumulation of deposits inside the pipework.

Management of loaded wastewater

It helps manage wastewater from plaster, polishing, grinding and cleaning of dental work.

Simpler maintenance

Settled sludge can be recovered regularly to keep the installation clean and functional.

Applications of plaster traps in dental laboratories

Wet model trimmer stations

The trap retains particles from trimming, shaping and cleaning plaster models.

Polishing and grinding

It limits the direct passage of sludge, dust and abrasive residues into laboratory drains.

Cleaning dental impressions

It helps manage rinsing water loaded with residues from impressions, models and prosthetic work.

Wastewater management

It contributes to cleaner and better controlled wastewater management in dental prosthetics laboratories.

GipEx Tabs flocculant	Accessory	Trap maintenance	Helps bind sludge and fine particles together

How to choose your Mestra plaster trap

14 litre plaster trap

The 14 L trap is suitable for small laboratories, individual workstations or installations requiring a compact under-sink solution.

19 litre plaster trap

The 19 L trap is suitable for regular activity. It offers greater volume while remaining easy to integrate into the laboratory workflow.

70 litre plaster trap

The 70 L trap is designed for more intensive laboratories, with a high volume of loaded wastewater and a need for less frequent draining.

Maintenance flocculant

The flocculant helps bind fine particles together and supports sludge recovery during trap maintenance.

FAQ — Plaster traps for dental laboratories

Why install a plaster trap in a dental laboratory?

In a dental laboratory, wet model trimming, polishing, grinding and cleaning operations generate solid residues. A plaster trap slows down the water flow so heavy particles can settle before discharge.

How does a plaster trap work?

The principle is based on gravity separation. Loaded wastewater slows down inside the trap, particles settle in the compartments and clearer water is discharged towards the drainage lines.

Which plaster trap capacity should I choose?

For an individual workstation, a 14 litre trap may be sufficient. For regular activity, the 19 litre model offers a good balance. For an intensive laboratory, the 70 litre model helps reduce draining frequency.

How often should a plaster trap be maintained?

The frequency depends on the volume of discharged water and the amount of residue generated. Regular monitoring of the sludge level is recommended to prevent fouling and maintain effective sedimentation.

Is a flocculant useful with a plaster trap?

Yes, a flocculant can help bind fine particles together and make recovery easier during maintenance. It complements the action of the trap, especially when wastewater is heavily loaded.

Does a plaster trap really protect drainage lines?

Yes, its role is to limit the direct passage of heavy residues into the pipework. It does not replace drain maintenance, but it significantly reduces deposits caused by plaster and laboratory sludge.

Laboratory tip

To maintain effective sedimentation, regularly check the sludge level, clean the trap according to your activity level and choose a capacity suited to the real volume of loaded wastewater generated by the laboratory.
