Q Labtech is a U.S.-based laboratory technology company.
Our patented technology features a pressure-release and
reseal system that prevents accidental explosions due to
over pressurization in the pressure reactor. Our products,
Q-Tube (pressure reactor) and QianCap (safety cap for
Ace type pressure bottles), are affordable alternatives to
microwave synthesizers. Our Fisher-Porter type of purging
systems can be used for hydrogenation and gas-filled
How Does Pressure Impact Chemical Reactions?
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
The Benefits of Our Products
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
Q-Parallel Synthesizer™ enable multiple simultaneous
reactions to be done in about 40 minutes; a great tool for
reaction optimization and pressurized parallel synthesis.
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 synthesis, catalytic hydrogenation,
polymerization, acid digestion process for accurate trace
metal analysis, like silver, and other chemical processes.
In addition to the above benefits using the Q-TUBE™ and
QianCap™ overa microwave synthesizer, Q-TUBE™ and
QianCap™ provide extra advantages of:
- Safety-virtually eliminating the risk of pressure
- Higher and cleaner product yields (microwave
energy is known to cause localized overheat which
accelerates decomposition reactions especially on
- Scalable (up to 1850 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
