       Q-TUBE™ and QianCap™ PURGING systems can be operated safely and accurately with high reproducibility
with a wide range of gases, including Ammonia, Nitrogen, Argon, Hydrogen, Deuterium, Carbon Monoxide,
Carbon Dioxide, etc.

Q-Optimizer™ and Q-Parallel Synthesizer™ enable multiple simultaneous reactions to be done in about 40
minutes; a great tool for reaction optimization and analogue synthesis.

What is the real temp for EtOH inside Q-Tube-35mL?
111°C ( Outside: 140°C); 129°C ( Outside: 160°C)

What does it mean to a reaction?  It means a reaction in
EtOH could complete in 15 min at 129°C instead of 8 h at
78°C.

  • ...I like the simplicity of the setup.  I think this will be a popular piece of equipment.  I will be using our
    microwave reactor less now that I have a Q-tube...
                                         
  • ...that a reaction in the Q-tube had a better purity profile than the product of the same reaction when
    performed in the microwave...
                                      
  • ...the good news is that the reaction worked very well.  It was clean and high-yielding (91%, vs. 70-80% in
    previous attempts).   15g scale, ~ 300 mL total volume in a 1 L pressure bottle and no safety issues to
    report...
                                       
  • ...I am constantly using your reactor It is excellent....

         Because of the safety and simplicity, Q-TUBE™
and  QianCap™ are approved by safety authorities
and in use  by world’s top pharmaceutical and biotech
companies, chemical companies and leading
academic institutes as safe, speedy and cost-effective
lab devices.

Chemistry Examples
Distributor:
       Q LABTECH is a U.S.-based laboratory technology company specializing in safe pressure reactors and
vessels.

        One of our innovations is Q-TUBE™ (patent pending).  Q-TUBE™ is a safe pressure reactor featuring a
pressure-release and reseal system (patent pending) that prevents accidental explosions due to over –
pressurization.  The same invention is applied on QianCap™ (patent pending) which prevents Ace-Threds™
pressure tubes/bottles from exploding.
The Principles of This Invention
       
       In addition to the above benefits using the Q-TUBE™
and QianCap™ over a microwave synthesizer, Q-TUBE™
and QianCap™ provide extra advantages of:

  • Safety-virtually eliminating the risk of pressure
    explosions
  • Higher and cleaner product yields (microwave
    energy is   known to cause localized overheat which
    accelerates decomposition reactions, especially on
    heterocycles)
  • Scalable (up to 2000 mL)
  • Higher Pressure than a typical pressure tube
  • Higher reproducibility (than a microwave)
  • Greener (broader solvent choices than microwave
    and conventional round bottom flask)
  • Energy savings (92 percent energy reduction and
    150 gallons of water per refluxed reaction)
  • Affordable,  only a fraction of a microwave
    synthesizer
  • Maintenance-free

Testimonies
       A pressure reactor enables a reaction to be carried out
at higher temperature than the boiling point of a solvent and
a reagent, which will increase the reaction rate (Arrhenius
Equation: every 10°C increase could double the speed).  
Pressure reduces reaction volume, including liquid, which
increases concentration and collision frequency, and in turn
speeds up a reaction.  When the desired reaction is
accelerated , the competing reagent decompositions are
minimized.  Pressure enables faster reactions with cleaner
profiles.


  
        Q-Tube-12mL and 35mL pressure reactors are
affordable alternatives to expensive and cumbersome
microwave synthesizers.  In addition to organic synthesis,
Q-TUBE™  and QianCap™ find use anywhere that higher
yields, cleaner products, and faster reactions are desired,
for example in inorganic synthesis, catalytic hydrogenation,
polymerization, acid digestion process for accurate trace
metal analysis, like silver, and other chemical processes.
