Twister Vacuum Mixer Bowl — Complete Bowl (Renfert)
The optimized geometry of the Twister bowl improves material circulation and promotes a homogeneous mix, with reduced air bubbles for cleaner pours in the dental laboratory.
- Transparent chamber: visual control of degassing and consistency.
- Maximum level mark + overflow collector to secure the cycle.
- Sealing designed for a stable vacuum and repeatable results.
Main features
- Material: transparent polycarbonate, thick walls, high resistance for daily use.
- Design: fill-level indicator + overflow collector (cleaner mixing station).
- Compatibility: designed for Renfert Twister vacuum mixers.
- Applications: vacuum mixing of dental gypsums, investment materials and silicones.
- Volumes: multiple sizes available (select according to your workflow and batch size).
Laboratory advantages
- Optimized degassing: fewer porosities, cleaner surfaces.
- Consistent mixing: improved homogeneity for gypsum and investments.
- Visual control thanks to the transparent bowl (consistency, bubbles, flow).
- Reliable vacuum: sealing designed for repeatable cycles.
Recommended use
- Dedicate one bowl per material (gypsum / investment / silicone) to prevent cross-contamination.
- Follow powder/liquid ratios and manufacturer times for consistent viscosity.
- Use a spatula to scrape the walls and homogenize the mix during the cycle.
- Avoid overfilling: the max level protects the system and the pump.

Usage & maintenance tips
- Rinse immediately after use with lukewarm water to prevent residue build-up.
- Clean with a mild detergent (non-abrasive): polycarbonate can micro-scratch with aggressive sponges.
- Avoid strong solvents (acetone, concentrated alcohol) that may damage the plastic and seals.
- Regularly check seals and lid: good sealing = stable vacuum and fewer bubbles.

FAQ — Renfert Twister Bowl
Why keep separate bowls for gypsum, investment and silicone?
Each material leaves residues (additives, surfactants, oils) that can affect the setting or flow of another material.
By dedicating one bowl per family, you reduce cross-contamination, stabilize your results, and save time on cleaning.
This is also a best practice to improve repeatability, especially with investments and precision gypsums.
How do you achieve a homogeneous mix with minimal bubbles?
Follow the powder/liquid ratio, start the vacuum before or right at the beginning of the cycle, then keep to the manufacturer timings.
Scraping the walls with a spatula during mixing helps homogenize the mass and limit dry zones.
The maximum level mark prevents overfilling, reducing air intake and overflow.
What precautions help preserve the polycarbonate and sealing?
Rinse immediately, clean with a mild detergent, and avoid abrasives that micro-scratch the bowl.
Do not use strong solvents (acetone, concentrated alcohol) that could damage the plastic or seals.
Regularly check the seals and lid: stable sealing is the key to a consistent vacuum and clean mixing.
Is this bowl compatible with all Twister mixers?
This bowl is designed for the Renfert Twister range. Compatibility then depends on the size/volume used in your configuration.
If you alternate several materials, plan multiple dedicated bowls: it prevents contamination and speeds up production at the mixing station.
