CAPILLARY REACTOR
In order to perform small-scale continuous reactions under definite
conditions, delay loops are required which have a predetermined reaction
volume to ensure a predetermined residence time and can
be operated at a
defined temperature. A simple setup to meet these requirements is a capillary
inserted in a heat transfer fluid. However, the geometrical configuration of the
capillary may strongly influence the width of the residence time distribution
which should be as small as possible to achieve favorable values of yield and
selectivity.
The capillary microreactor module consists of a stainless steel capillary
multiply coiled in an 8-shaped geometry. The temperature is set by means of
two electrically heatable cartridges inserted into the two regions enclosed by
the coil. In order to control the reaction temperature, Pt 100 temperature
sensors are embodied in the heatable cartridges and attached to the capillary.
The 8-shaped configuration in connection with the strong curvature of the coil,
which leads to additional secondary flows, results in a favorably narrow
residence time distribution. The total volume of the heated capillary is usually
4 mL which corresponds to a residence time adjustable between 0.1 to
20 minutes when regarding a throughput range of 0.2 to 50 mL/min
characteristic for a standard HPLC pump.
The capillary can be replaced by a corresponding spare part or capillaries
made from other materials can be inserted when appropriate for special
reactions.

BLOTTING MEMBRANE SANDWICHES
Whatman offers an extensive line of blotting membrane sandwiches that are made with our high quality Protran® nitrocellulose or Westran® polyvinylidene fluoride (PVDF) membranes interleaved with
superior 3MM blotting filter paper.
Time saving blotting sandwiches
The Blotting Sandwiches consist of a transfer membrane between 3MM blotting papers in a sandwich format. The pre-cut membrane with papers matches the most commonly used pre-cast electrophoresis gels. These blotting sandwiches offer convenience and time savings for high throughput labs using chemiluminescent detection or other common detection methods. The “ready to use” sandwiches are offered with Protran, which is of 100% nitrocellulose, or alternatively with Westran PVDF membrane.
Protran is a UNIVERSAL blotting membrane suitable for Western (protein), Southern (DNA) and Northern (RNA) blots and has a very high binding capacity due to its sponge structure. Protran is hydrophilic, which means that no pre-wetting with toxic methanol is required. It is suitable for all common detection methods (radioactive, colourimetric, fluorescent, as well as chemiluminescent detection based on horseradish peroxidase systems like ECL/SuperSignal/Luminol and all common staining methods).
Westran CS protein blotting membrane and Westran S protein sequencing membrane are both hydrophobic PVDF, an excellent support for protein transfer due to its high affinity for proteins and its broad compatibility with detection and analysis systems. Westran CS (Clear Signal) is specifically designed for Western blotting and protein dot-blotting applications. The membrane features high protein capacity and increased signal over a wide range of molecular weights.
Westran S has a very high protein binding capacity and excellent chemical resistance and is ideal for protein sequencing. It is also compatible for use in non-sequencing Western Blotting applications.

UTR200 - POWERFUL ULTRASONIC REACTOR FOR IN-LINE USE
The sonoreactor UTR200 (200 watts, 24kHz) works as an ultrasonic bath but at a 50 times higher intensity. Its characteristics in terms of quality are the same as those of the other Hielscher
ultrasonic processors, such as the UP200S . In addition, it is dry-running protected. It is suited for the direct or indirect sonication of liquids e.g. for cell disruption, homogenizing or emulsifying . The beaker-shaped sonotrode is machined from one piece in order to prevent leakages. The upper part of the sonotrode is oscillation-free and can be used for mounting the respective accessories for diverse application cases. A corresponding reactor cover takes the Eppendorf tubes or test tubes for indirect sonication. For a more intense sonication of vials and test tubes for processes, such as dispersing, homogenizing and emulsifying, please take a look at our VialTweeter.
By means of the reactor cover the chamber is hermetically sealed. If the cover has an additional inlet and outlet the sonoreactor can be used as a flow system. A sieving extension with a bajonet lock takes a pile of sieves for fine grain sizes (diameter 75mm, finest mesh size 5 micron). The ultrasound, which is transmitted to the sieves, accelerates the wet sieving process.
Besides the application combination with various accessories, the UTR200 is a powerful alternative to common ultrasonic baths.

700 BAR REACTORS
Small volume, high pressure autoclaves
A range of high pressure stirred autoclaves to 10 litres and 700 bar available as a standard. Constructed from stainless steel or Hastelloy.
Small volume high
pressure autoclaves with integrated magnetic coupling with rpm measurement, gas entry and vent valves, pressure gauge and bursting disc. Shown is a range of stirred and unstirred autoclaves.
Shown are autoclaves rated to 700 bar with pressure gauge, bursting disc, valve and an optional thermocouple.
Versions up to 200 bar are available with quick release clamping system. Larger vessels 60 ml and above are available with additional entries and dip pipes, sampling systems, cooling coils, etc.
The HTM system incorporates an electrical heater with copper adapters to allow different size bodies to use the same heater while still keeping good heat transfer.
The motor is mounted so that it may swing out to allow removal of the vessel.
The HTM unit is fitted with all necessary connections to control heating, cooling (via cooling coil) and electrical connections.
The HPM pneumatic base unit allows all cover connections (gas, vent, liquid, etc.) and the drive motor to remain in place while the vessel is removed.
The vessel is fitted into the heating body which is then pneumatically raised to meet the cover. This allows a greater throughput of reactions without time consuming and fiddly disconnection of services after each run.
A control system is available to accurately control heating and rpm while displaying the temperature in the vessel, the rpm and the pressure.

CRYOREACTOR
The CryoReactor was originally developed to perform continuous small-scale
organometallic reactions at low temperatures. The essential prerequisites were
precooling of the reactants, mixing at low
temperature and chemical
transformation in a cooled delay loop ensuring a definite residence time. In
order to meet these requirements, a system was designed comprising two
capillary-type heat exchangers, a multilamination micromixer and a reaction
capillary which are placed together into an insulated steel vessel (“Dewar”)
filled with a cryogenic agent. Accordingly, the CryoReactor combines several
functions and can be regarded as an integrated unit.
The CryoReactor module satisfies completely the prerequisites of the
Modular Microreaction System and can be combined with all other modules.
Materials in contact with reactants are as usual stainless steel and
perfluorinated elastomers and polymers, respectively. The module can easily be
connected to the coolant circulation of an external cryostat unit and operated
at temperatures down to -100 °C.
With some minor modifications the module is similarly appropriate for hightemperature
applications. It can be operated up to temperatures of +300 °C.
