Series 4590 Micro Reactor Systems
4597 Micro Reactor, Fixed Head, 50 mL, and a 4848 Reactor Controller with optional Expansion Modules.
T
hese are the smallest of all Parr Stirred
Reactors. They will be a good choice for
chemists working with very expensive materials
or materials only available in small amounts.
They will also appeal to users who wish to
minimize the risks associated with hazardous
materials or reactions by restricting the reactants
or products to a minimum. Use of the Series
4590 Reactors also helps minimize the quantities
of waste products which may require special
disposal procedures. The 4590 systems are now
available in high pressure (5000 psi) or high pres-
sure/high temperature (500 °C) versions.
These micro reactors have been designed to
provide as many of the features of the larger ves-
sels as possible in the limited space available. All
of the standard head fittings are provided, with
optional cooling now available with aluminum
block heaters with cooling capability, welded
jackets or Cold Fingers.
These systems are offered in both fixed head
and moveable head vessel styles with choices
of a self sealing O-ring for temperatures up to
225 °C or with FFKM O-ring for temperatures to
275 °C or with a flat PTFE gasket for temperatures
to 350 °C, or with a Flexible Graphite gasket for
temperatures to 500 °C with the HP/HT option
(for fixed head versions only). A split ring closure
is standard.
All three volumes use the same ceramic fiber
heater.
These micro reactors can be easily converted
from one size to another by simply substituting a
larger or smaller cylinder and the corresponding
internal fittings. The support system can also be
readily adapted to accept any of the vessels from
the 4560 Mini Reactor Series. The opportunity to
modify these small reactors is restricted because
of the limited head space available.
