Why Traditional Dilution Methods Fall Short
Many laboratories still rely on pre-filled dilution bottles for sample preparation. While familiar, this approach comes with serious drawbacks:
❌ Inconsistent results due to operator-dependent methods
❌ High contamination risk with open bottles
❌ Recurring costs from single-use consumables
❌ Slow, manual workflows that consume staff time
❌ Excessive waste from disposable plastics
❌ Vulnerability to supply availability and consistency
As labs face pressure to improve efficiency, reduce costs, and ensure data accuracy, the limitations of diluent bottles are more apparent than ever.
Introducing the Smart Dilutor W with Filter

The Smart Dilutor W with Filter is designed to solve these problems.
With its closed, semi-automated system, labs gain more reliable results while reducing the risk of contamination.
If you already own a Smart Dilutor W, you don’t need a new unit. Our Filter Starter Pack easily upgrades your existing system.
Benefits of the Smart Dilutor W with Filters
1. Gravimetric Dilution Accuracy
- Uses mass-based measurements instead of manual volume-based methods.
- Ensures reproducible results independent of the operator.
- Improves data integrity and reduces variability.
2. Lower Contamination Risk
- A closed system using autoclavable materials (except the filter).
- Reduces microbial contamination compared to open sterile bottles.
3. Cost Savings
- Eliminate recurring consumable costs.
- Only startup and low maintenance expenses.
- More sustainable long-term investment.
4. Faster Processing
- Semi-automated workflow speeds up dilutions.
- Frees up lab staff for critical tasks.
5. Reduced Laboratory Waste
- Less plastic consumption.
- Supports sustainability goals.
6. Reduced Supply Dependency
- Only the filter is required as a consumable – no ongoing reliance on bulky sterile diluent bottles.
- Less exposure to supplier shortages and stock disruptions.
- Ensures smoother, more reliable lab operations.
