CO-ROTATOR

The co-rotating twin extruder is an intelligent tool for simulation of Industrial processes in labs and pilot plants. Multiple dies and additional tools enables a easy change over to multiple application.

For the mapping of wafers or for the automatic analysis of the surface free energy of flat samples such as paint test plates or optical lenses. The ETT/VAC can be equipped with any of a range of different top plates. The fixation of the samples on the top plates is achieved by the application of a vacuum, connected to the turn table.

• FSH 30special holder, made of delrin, for the contact angle measurement on thin films. Consisting of base (outer-=30 mm) and three rings (inner-= 30.0 / 30.1 / 30.2 mm).
• FSC 80special holder for the contact angle measurement on thin films or paper;Maximum sample size 80 x 80 x 3 mm.
• FSC 150special holder for the contact angle measurement on thin films or paper;Maximum sample size 150 x 90 x 3 mm.

The tilting base unit, TBU 90E, is an important instrument extension for the analysis of hydrophobic materials. It allows the measurement of the advancing and receding contact angle, the rolling angle and the contact angle hysteresis of sessile drops while maintaining a constant visual plane (optics / sample). In conjunction with the SCA software; it facilitates the fully automated execution of rolling angle experiments up to a tilt angle of 90and at freely adjustable tilt speed of 0.03 to 2.8 /s.

It is well known that the elongational flow behavior, which dominates many processing techniques, can not be determined from shear experiments. The patented Rheotens melt tensile testing technique has proven to be highly reproductable and sensitive and will differentiate even polymer melts showing differences in molecular structure, which cannot be detected with other analytical methods.

Glass cell (cuvette) made of special optical glass for measuring the interfacial tension between two fluids according to the Pendant Drop method or the contact angle of a fluid drop or a gas bubble in a fluid (e.g. Schultz method) ; up to 70 C.
Also available in 'high' temperature version (GC xxHT) and made of Quatrz glass (GC xxQ); 70 to 350 C.

Whether your application demands the evaluation of contact angle or drop shape, the video-based optical contact angle measuring system, OCA 15EC, is the instrument of choice where initial budgets are limited. The single direct dosing system, SD-DM, together with the electronic dosing unit, ES (both included within the 'system' configured, under the OCA 15EC part number) enable the precise and accurate handling and dosing of liquids.
The OCA 15EC can be easily broken down for transportation in the optional case, TBO.

The Blown Film Unit is a compact unit for blowing, cooling, take off and wind up of extruded hoses. It is suitable for production of small films used by the food industry and in the packaging field where the application of big production machines is often not profitable.

One of the most outstanding features of the MINI BYPASS RHEOGRAPH MBR is its compact size. With a width of approx. 150 mm this new system is one of the smallest on-line rheometers available. Even in tight space this new design can be installed without problems. The measuring head weight of only 30 kg eliminates costly mounting arrangements. A new die exchange system makes die changes quick and easy.

The Side Stream Rheometer is based on the first melt return online capillary rheometer developed by GTTFERT many years ago. The new SSR uses the same annular melt transfer line as the old (the advantage is that only one tap hole is needed, making installation simple) and no waste stream is generated because the tested material is returned.

The Melt Indexer MI-2. This unique melt indexer can carry out a single weight test according to ISO 1133 and ASTM D1238, procedures B, as well as ISO 1133 and ASTM D1238 Procedure C for the "Half Height / Half Diameter" standard.

GTTFERT Laboratory Extruders are not only just Melt Feeder, but also self-sufficient measuring equipment - therefore Extrusiometer!
Flexible in diameter and length, as well as cylinder systems designed according to customer preferences, the numerous positions for pressure transducers or the melt temperature acquisition are only a few highlights of the Extrusiometer family. The shear rate, shear stress or the viscosity are being displayed online. The platform offers also a wide range of options and add-onn systems, like different dies, Online Rheometers, Extensional viscosity testers, film analysis. The Software can be connected to superior Bus systems. With an optional self running Online Sampler System for material feeding a non-stop operation is guaranteed. Please see also the separate brochure At-Line Station for more details.
