   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.
Q Labtech specializes in safe glass pressure reactors
     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.
The Principles of This Invention
The Benefits
     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
