Glass Handicraft

TOPTION glass material is even-thickness & no foam. Glass cover is handmade fired with very good annealing temp. So TOPTION brand glass reactor has no crack during working process.

Mechanical Seal

Stirring seal plug adopts “mechanical seal, dynamic ring & static ring buckle principle”, guarantee good sealing function and stirrer service life.


Motor with stable performance, over-temp. never happen even with long time operation.

Speed Regulator

TOPTION speed regulator use variable frequency regulation, ensure your research stable & accurate even through your laboratory current voltage is flutuating.

Bottom Discharge Valve

Achieve quality by design, bottom discharge valve ensure reactor no dead angle, no liquid leakage & corrosion phenomena.

PTFE Seal Material

High quality PTFE seal material, even under high temp. reaction, ensure no decompose & corrosion.

PT-100 Temp Sensor

Whole temp. testing parts use PT100 temp. sensor, which has good sensitivity. Temp. sensor through good antiseptic treatment (especially the outside PTFE coated technique), guarantee temp. testing result keep accurate, no temp. drift, temp. sensor no corrosion.


Stirrer is full coated with PTFE, ensure its long service life, without corrosion, ensure continuously good stirring effection.

Support Frame

Reactor whole support frame use stainless steel material – thickness ≥ 1.5mm, guaratee continuously good bearing load performance during reactor long service life.

Screws Use Stainless Steel

Reactor’s all screws use stainless steel material, from details promising reactor good quality and long service life.

Reactor’s Lockable Wheels

For reactor’s lockable wheels, TOPTION design standard bearing force is equal or greater than 1.5 time (equipment weight + liquid sample weight). For long-term consideration, ensure your research be safe and convenient.


TOPTION core technology could support laboratory design and overall arrangement, so as to meet different process requirement from different customers.
