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 pressurized reactions.
How Does Pressure Impact Chemical
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 Dioxide, etc.
Q-Parallel Synthesizer™ enable multiple simultaneous
reactions to be done in about 40 minutes; a great tool
for reaction optimization and pressurized parallel
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
- 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 heterocycles)
- 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
