Featured instrument
BT300S variable-speed peristaltic pump
A workhorse metering pump for anyone who needs a known volume moved, repeatedly, without contaminating it. The fluid only ever touches the tubing — so a channel change is a tubing change, not a teardown.
- 0.006 – 1,600 mL/min across ten interchangeable pump heads, up to four channels.
- Time-dispense mode — set dose duration, lag between doses and cycle count, then walk away.
- RS485 MODBUS plus optically isolated logic and analog inputs for PLC or HMI control.
- Stainless enclosure rated IP31 and resistant to acids, alkalis and organic solvents.

Why Dragon Labs
Equipment chosen by people who use it
We're a small operation, which is exactly why we won't list something we can't stand behind.
Configured properly
Pump heads, channel counts and control options are selected before you order — so what arrives matches the method you wrote.
Checked before it ships
Instruments are powered up, run through their control modes and inspected for transit damage before they leave the bench.
Support that answers
Questions about tubing sizing, MODBUS registers or dose programming go to someone who has actually set the instrument up.
Straight paperwork
Clear pricing, a plain-language warranty and no surprise handling fees at checkout. Quotes and W-9s on request.
Where it's used
Built for the jobs that repeat
Anywhere a fixed volume has to move on a schedule, a peristaltic pump is usually the honest answer. Here's where ours end up.
- Water & wastewater dosing — coagulant, chlorine and pH-adjustment feed at a controlled rate.
- Analytical sample transfer — moving samples and reagents without cross-contaminating the wetted path.
- Automated test rigs — driven from a PLC or data-acquisition system over RS485 or 4–20 mA.
- Small-batch filling — repeatable dispensing into vials, bottles and pouches with anti-drip cut-off.
