S-flow IV⁺ Kinematic Viscometer

“The newest generation of S-flow systems offers the ultimate in fast, accurate viscosity testing and now also features an optional autosampler for fully unattended operation.”

Maximum throughput and ease of use with very low sample and solvent consumption

 

The latest generation of new S-flow builds on the strong foundation of its predecessors to offer the ultimate in automatic viscosity testing of Newtonian samples such as petroleum products. The system offers all the tried and tested advantages of a Houillon-type tube design such as short process times, small sample volume and low solvent consumption, but now also includes an optional autosampler to allow for fully unattended operation. All controlled from a central user interface that takes care of result storage, autosampler control, VI calculations and much more. It complies fully with ASTM D7279 and as such, provides full correlation to ASTM D445. It is the ideal system for used oil analysis labs that need to test a wide range of lubricant viscosities.

The new S-flow IV+ consists of a 2 bath system with 2 tubes in each bath, providing a total of 4 tubes. The baths were designed to work independently, making it possible to use both baths at the same temperature, or at different temperature, ranging from 20°C to 120°C. Other options include dual solvent cleaning and integrated duplo testing which obtains 2 flow time determinations with only 1 sample injection.

All measurement parameters, such as warmup times and cleaning parameters can be set through the high resolution 12” touchscreen or with optional PC software. The diagnostic system alerts the operator to possible issues such as empty solvent supply tanks, full waste bottles and other potential issues. The optional auto-sampler is fully modular and in-field upgradeable, meaning you can purchase the analyser first and then upgrade to auto-sampling when the need arises.

Optional accessories & upgrades

Following items are optional accessories and upgrades to the instrument.

 
Dual solvent cleaning

A suitable solvent used for cleaning should have the following two main characteristics:

  •  It should be able to dissolve the sample that was tested, i.e. clean the tube completely
  •  It should evaporate quickly enough at the bath temperature so that the tube is fully dry after cleaning

If the solvent used does have the ability to dissolve the sample, but does not evaporate quickly enough, a second solvent can be used to rinse out the first solvent, as well as dry the tube. Usually, low boiling solvents are used for this purpose, such as Acetone or MEK. 

 
Cooling circulator

For measurements close to ambient (± 8°C), an additional cooling circulator is required to create sufficient offset for the temperature control unit. Each bath is fitted with a cooling spiral, to which an external cooling circulator can be easily connected. Complete with tubing and fittings.

U-Visc kinematic viscometer

“The U-Visc viscometry system was designed with full ASTM D445 compliance in mind, combined with low solvent consumption, high unattended throughput, ease of use and reliability”.

The Omnitek U-Visc is the next generation of completely automatic viscometry systems.


The system combines several unique features, making it the instrument of choice in many applications, ranging from QC to R&D to used oil analysis. While offering full compliance with ASTM D445/446, the specially designed viscometer tubes cover a 100-fold range, e.g. from 1 to 100 mm2/s. The tubes are based on the well-known and proven Ubbelohde design, but only require 8-16 ml of sample and approx. 12-15 ml of solvent for cleaning. Available with single or dual solvent cleaning, the instrument measures kinematic viscosity in Newtonian fluids like lubricants, fuels or dissolved plastics between 0.15 and 25,000 mm2/s.

Designed to be versatile and flexible, yet easy use. Different models are available range from 1 bath with 1 or 2 viscometer tubes, up to 2 baths with 1 or 2 viscometer tubes per bath, where ach bath works independently. Sophisticated temperature control ensures that measurements are carried out well within limits specified by ASTM D445. Each bath features a 32-position sampling tray (16 samples per tube), allowing completely unattended operation. Depending on the viscosity of the sample, the instrument can process up to 40 measurements per hour, satisfying even the needs of high volume labs running several hundred samples per day.

Samples can be introduced using vacuum or pressure. The latter avoids evaporation of sample, which can be a point of concern in some dilute viscosity applications. Viscometers are easily exchanged in minutes instead of hours, minimizing downtime. All surfaces of the viscometer tubes, including the outside bottom, which is in contact with the sample, are thoroughly cleaned and dried using solvents and air.

BitUVisc kinematic viscometer

“Finally an instrument that eliminates the need for the tedious, labour intensive manual loading, measurement and cleaning of high viscosity samples”.

Omnitek ‘BitUVisc’ is a programmable, fully automatic kinematic viscometer specially designed to handle highly viscous samples at high temperatures.
 

The system can process samples with viscosities ranging up to 120,000 mm2/s, up to 150°C. It fully complies with ASTM D445, D446, D2170 and AASHTO T201.

There are 2 different models available: 110 and 120. BitUVisc 110 features a single thermostatic bath with 1 viscometer tube whereas BitUVisc 120 model holds 2 viscometer tubes in a single bath. All BitUVisc instruments are equipped with auto-sampling, preheating, fully automatic dual solvent cleaning and drying.

Viscometer tubes are based on the well-known and proven Ubbelohde design. Using specially designed thermal sensors, these tubes allow the detection of fully opaque fluids without any problems or limitations and eliminate the need to use the reverse flow tubes. The standard configuration offers viscosity measurement up to 150°C and sample preheating up to 200°C. 

Sophisticated temperature control ensures that measurements are carried out well within the required temperature stability. The system features an innovative single position auto-sampling which provides integrated heating of the sample up to 200°C and uses preheated solvent to effectively clean the viscometer tube. The BitUVisc is fitted with special designed duplo viscometer tubes for unstable samples such as vacuum residues, additives, crude oils, waxes, heavy fuel oils, polymers, asphalts, etc., which typically show poor determinability when sampled repeatedly. These tubes have 2 measuring sections with an approximately similar tube constant. This allows for an actual duplo determination while only sampling once.

S-flow Houillon viscometer

“The S-flow system was designed for maximum throughput and ease of use while minimizing sample quantity and solvent consumption. It is the ideal viscometer for quick and accurate results”.

Maximum throughput and ease of use with very low sample and solvent consumption

 

The S-flow range of instruments consist of compact, bench-top automated viscometry systems for the analysis of Newtonian fluids. It complies fully with in ASTM D7279 and as such, has a direct correlation with ASTM D445. It is the ideal system for used oil analysis labs that need to test a wide range of lubricant viscosities. Quick analysis time, small sample size and low solvent consumption, combined with extreme ease of use and reliability make it the instrument of choice for many of our world-wide users.

The S-flow system is a self-contained viscometer system that consists of an accurately controlled thermostatic bath and a control touchscreen. Different models are available with either 1 or 2 baths, each of which contains 4 Houillon style tubes. Highly accurate optical sensors detect the flow of the sample through the viscometer tubes to obtain flow time results with 0.001 sec. precision. All measuring viscometer tubes function fully independently of each other allowing for very high throughput. 

Additional parameters such as tube constants and cleaning cycle are also controlled by the operator. Only requiring 0.3 ml of sample, the system performs the measurement very quickly, allowing a throughput of up to 80 tests per hour per bath. Options include dual solvent cleaning and integrated duplo testing which allows the operator to perform 2 flow time determinations with only 1 sample injection.

Versions 

Omnitek S-flow is available in 3 different models
