Sample Preparation & Processing


High-performance Grinding Down to the Nano Range


With two grinding stations, Fritsch have developed the new Planetary Mill PULVERISETTE 5 premium line as abig sister to the PULVERISETTE 7 premium line: It is the ideal mill for fast wet and dry grinding of hard, medium-hard, soft, brittle and moist samples as well as for mechanical alloying, mixing and homogenising of larger sample quantities with reliable results down into the nano range, and absolutely secure automatic clamping of the bowls by the mill.


The Planetary Mill PULVERISETTE 6 premium line features extra strong 2.2 kW drive power and extremely high centrifugal acceleration up to 64 g and up to 800 rpm (rotational speed of the bowl 1600 rpm). The two grinding stations are suitable for 125 to 500 ml bowl volume.


With the completely brand new ServoLOCK clamping of the grinding bowls and the automatic check of the fastening of the bowls inside the mill, man and machine are optimally protected. In the event of impermissible operating states, the machine blocks the start of a grinding and if an imbalance occurs it automatically shuts off.


The grinding bowl is simply inserted in the PULVERISETTE 5 premium line from the front into the holder. Correct positioning is automatically ensured by a practical guide. The PULVERISETTE 5 premium line does not start until both bowls are correctly inserted and due to bowl detection via RFID chip, prevents the setting of too high speeds depending on the bowl material used.


The revolutionary ServoLOCK is activated with a single hand motion by pressing down the clamp. It is automatically locked by the machine via ServoLOCK instead of manually. A LED light shows that the bowl is correctly inserted and clamped.


The PULVERISETTE 5 premium line is operated via the adjustable, ergonomically arranged touchscreen with high-resolution and logical menu structure in multiple languages and practical plain-text user navigation for fast and easy operation. Here you enter the variable rotational speed and define the grinding time. You can programme interval and pause times using the minutes and seconds timer and can save up to 10 programmes.

Optimised Bespoke Glass Laboratory Reactors


Asynt reports on an increasing demand for bespoke glass laboratory reactor systems, optimised to meet the exact demands of an application or project. As a respected supplier of off-the-shelf laboratory reactor systems, Asynt has the in-depth knowledge and glassware manufacturing expertise to also offer customised glass reactor vessels ranging from tens of millilitres to 50 litres in capacity.


A polymer resin manufacturer commissioned Asynt to develop a 20-litre jacketed glass laboratory reactor vessel with a bespoke 30mm diameter zero dead space bottom run off valve. Because of the viscous nature of the reaction material this valve was essential to the project, allowing for simple product sampling and ensuring easy and efficient transfer of the reaction material. The customer was so pleased with the operation of the resulting glass reactor that they ordered a second identical system.


A contract research organisation, specialising in the synthesis of photosensitive molecules, tasked Asynt to design a 1-litre glass laboratory reactor to minimise light degradation of their high value molecules during reaction. This was achieved by manufacturing the complete reactor system using amber-stained glass.


The Asynt team has over 30 years of dealing with custom glassblowing solutions and can help you with many of your custom glass reactor needs; whether you require just a small adaption or a fully bespoke glass reactor system.

Versatile Evaporator Available in Different Optimised Confi gurations


The compact benchtop EZ-2 Series evaporator from Genevac has been designed to meet or exceed the solvent removal needs of most laboratory scientists.


Using the most advanced proven technology in evaporation science, the EZ-2 Series has been designed specifically for solvent removal in many areas of scientific research, whether concentration of samples or complete drying is required.


For many applications an optimised EZ-2 evaporator is available to suit your solvent removal needs. The EZ-Envi is created specifically for concentration of volatile solvents prior to analysis, the EZ-Standard for drying water and volatile solvents, the EZ-2 Plus for working with solvents with higher boiling points up to 165°C and the EZ-2 Elite for more difficult solutions such as DMSO and NMP, or fast freeze drying. EZ-2 evaporators can be further modified for the most difficult and hazardous solvents, a special model exists for those working with potentially explosive solvents such as diethyl-ether. Alternatively, for laboratories who remove concentrated acids and acid chlorides, a corrosion resistant construction EZ-2 HCl is the system of choice.


Each EZ-2 evaporator is compatible with a wide selection of sample holders enabling evaporation from sample container formats including round-bottom flasks up to 500ml, tubes up to 150mm long, vials, and custom reaction blocks as well as shallow and deep-well microplates.


Running an EZ-2 evaporator is easier than a rotary evaporator. Just load your samples, select maximum safe temperature for samples, select solvent type and hit start. Offering true unattended operation through use of pre-programmed methods an EZ-2 Series evaporator requires minimal user training, even a beginner can competently use the system within 5 minutes.
