1200°C Ultrasonic Spray Pyrolysis Vertical Furnace with Continuous Collection 3 Zones
Reference: VTLF1200
Manufacturer: Across International
- Atomizer: 2.4 MHz ultrasonic atomizer that converts the liquid into fine droplets fed into the tube furnace. Connected to a stainless steel liquid-collection reservoir so un-atomized liquid cannot enter the tube.
- Liquid flow control: precision syringe pump (10 µL–60 mL syringe capacity; flow range 0.184 nL/min–83.318 mL/min; stroke accuracy <±0.35%; RS485 / Modbus).
- Heating section: tube furnace, 1200°C max.
- Continuous nano-collection unit: 60 mm dia. collection canister with gate valve for emptying without breaking the process.

This vertical tube furnace uses low-energy ultrasonic vibration to atomize a liquid precursor into fine droplets. The liquid is delivered to the spray head by a syringe pump for continuous or intermittent atomization, then reacts in the high-temperature zone. Synthesized nanoparticles carried by the flowing gas and free-fall settling are efficiently collected in a stainless steel canister.
Typical applications: thin-film spray coating (solar cells, fuel cells, touch screens, soldering flux, glass film coating) and nanomaterial synthesis.

What customers say about our store
Quick and reliable service provided! - Scheduled an appointment with Wayne the other day for a Dry Ice order pick up, he will go over and above for his customers to make sure we are well taken care of. Even with a broken foot !
Thanks again Wayne!
You've got my business!
Wayne there has an excellent store, he has everything, really nice stuff at good prices, ultimately very fair compared to others. I will certainly be going back for everything I need. Got some things from a different place and spent 50% more, just go see Wayne first, he seems like he wants to help you out more than sell you out the door.
