ALab™ dFlow-Pro Electronic Bottle-Top Dispenser
Product Detail
The ALab™ dFlow-Pro is a touchscreen electronic bottle-top dispenser with multiple dispensing modes, in three sizes with working ranges from 0.01 to 10 mL, 0.02 to 25 mL and 0.02 to 50 mL. Dispensing accuracy complies with ISO 8655-5.
A 4.3-inch TFT color touchscreen sets the dispensing programs, aspiration and dispense speed is adjustable in 10 levels for different viscosities, and six modes cover manual and automatic fixed-volume dispensing, multi-step and custom programs, free dispensing and titration.
The consumable-free, low-maintenance design has a built-in 0 to 90° rotary valve with quick venting and reagent recirculation, a standard drying tube for moisture- and CO2-sensitive reagents, and transparent and amber windows as standard. The dFlow-Pro connects to a PC over Type-C and WiFi and stores 1000 experiment records.

Dispensing modes six modes
| Dispensing mode | How it works |
|---|---|
| Manual fixed-volume dispensing | Set the volume (mL); aspiration and dispensing are controlled manually. |
| Automatic fixed-volume dispensing | Set the dispensing interval, volume and repetitions; trigger the first dispense manually, then the program continues at the set interval. |
| Automatic multi-step dispensing | Set volumes for up to 10 steps (total not exceeding the piston capacity) plus the interval time; trigger the first dispense manually, then the program runs at the set intervals. |
| Manual free dispensing | Aspiration and dispensing volumes are controlled manually. |
| Custom dispensing | Define steps, intervals, volumes, aspiration and dispensing, and save them as a program for future use. |
| Titration | Manual or continuous titration until stopped, with the titration volume displayed (e.g., volumetric flask preparation, pH adjustment). |

Where it fits
Frequently asked questions
Which sizes are available?
Three sizes: 10 mL (0.01 to 10 mL, min. 10 µL), 25 mL (0.02 to 25 mL, min. 20 µL) and 50 mL (0.02 to 50 mL, min. 20 µL).
How accurate is the dFlow-Pro?
At the nominal volume the systematic error is ±0.5% and the random error ±0.3% (10 mL) or ±0.25% (25 and 50 mL); dispensing accuracy complies with ISO 8655-5. The values per measured volume are in the accuracy table.
Which dispensing modes does it have?
Manual fixed-volume, automatic fixed-volume, automatic multi-step (up to 10 steps), manual free, custom dispensing with saved programs, and titration.
Can it handle light-sensitive reagents?
Yes. Transparent and amber windows are standard; the amber window suits light-sensitive liquids such as iodine solution, potassium permanganate and silver nitrate.
Does it need consumables?
The dispenser has a consumable-free design. For moisture- or CO₂-sensitive reagents, users can add a compatible absorbent to the standard drying tube.
How does it connect to a PC?
Over Type-C and WiFi; Bluetooth is also available, and the memory stores 1000 experiment records.
