Tensiometers for taking surface measurements including contact angle and surface tension

Tensiometer - Easy to use, high precision instrument that is flexible, versitile and accurate.

The Sigma 701 is a multipurpose tensiometer based on the successful Sigma 700 but now equipped with a more sensitive microbalance optimised for a different range of applications. The basic Tensiometer can be up-graded to fully-equipped R&D workhorse to cover many of the mass-based methods you might need.

You can run two dispensers simultaneously for CMC measurements and the high resolution balance make it possible to measure single fibres only a few microns in diameter. An ideal tool for those looking for a high performance with high resolution, user-friendly, standard tensiometer as well as for anyone looking for exacting performance and precision in high end applications requiring resolution higher than that traditionally available.

Key features:
• Large working space; wide opening doors
• Dispenser and inert gas ports
• LED illumination of measuring compartment
• Built in stirrer, no moving parts, no magnetic field during measurement
• Built in connectors for temperature and pH sensors
• Auto-locking and auto-calibrating microbalance
• Static charge eliminator
• High speed/extended length movement of sample stage
• Small and light measuring capability (e.g. single fibres)
• Thermal separation space between balance and measuring compartment
• Removable measuring compartment for customised future measuring options such as Langmuir studies, high temperature applications, bursting membrane tests and X-Y sample positioning
• Enlarged pull-down sub-window for on-line viewing of selected data
• Optional synchronised dual dispenser software for dilution CMC measurements of highly concentrated solutions.

Available Measurements
• Static surface tension
• Static interfacial tension
• Density
• Dynamic contact angle
• Surface free energy
• Wettability
• Automatic critical micelle concentration

The low surface energy of many polymer-based substrates often leads to poor adhesion of inks, glues and coatings. To obtain optimum adhesion, it is often necessary to increase the surface energy of the substrate to just above that of the material to be applied. Corona Treatment Equipment, Plasma Treatment Equipment and Flame Treatment Equipment all give good treatment levels and result in good wetting of the material over the surface of the substrate and so improves surface energy.

CORONA TREATMENT EQUIPMENT
Dyne Technology supplies Corona Treating equipment solutions to help our customers improve the surface energy of their plastic & rubber components to ensure good bonding of printing inks, paints, adhesives etc. Corona Treating Equipment (including corona pens) is widely used throughout a diverse range of industries and onto an ever increasing range of substrates. Our growing list of customers using corona treatment includes many in the following industries: medical, electronics, automotive component, cable, ophthalmic, pipe, printing, packaging, domestic appliance, cosmetics packaging, food and beverage packaging, and many more. Through our many years of experience and continuous product development we have become one of the leading suppliers of Corona Treatment equipment.

Corona treating systems can be easily integrated into existing production lines or installed as stand alone corona treatment machines.

We offer 5 corona treatment solutions:
1. Rotating Electrode; This universal corona treatment system operates with special rotating corona electrode elements resulting in complete and uniform corona treatment of the parts. It offers a cost-effective method for optimising the adhesion properties of printing inks and coatings onto 3D parts made from low surface energy polymers such as polypropylene and polyethylene.

2. Fixed Electrode; This versatile system operates using a wide range of electrode systems ranging from simple "wire" electrodes, high performance "ball" electrodes or highly durable ceramic electrode elements resulting in complete and uniform corona treatment. Fixed electrode corona treatment systems can incorporate air jets to support the feed of parts through the corona treating station.

3. Spot Treater; This corona treatment unit creates a high voltage, low frequency corona discharge to treat the surface of 3-dimensional moulded or extruded plastic parts, profiles, webs, containers, etc. An airflow presses the corona discharge towards the substrate to be treated and a counter electrode is not necessary.

4. Narrow Web Treater; This system is designed for the corona treating of conductive and non-conductive narrow webs, labels etc. This type of corona treating system can be supplied to treat either one or both sides of the web and will accommodate widths from 100-500mm, running at production speeds of up to 150m/min.

5. Wide Web Treater; This corona treatment system is designed for the flexible packaging and printing industries and offers increased surface energy on webs manufactured from a variety of materials including; paper, plastic, metalised film and foil. The compact design of the corona discharge unit enables the equipment to be easily installed into new or existing extrusion, printing, coating and laminating lines.

What ever your equipment needs are in the field of Corona Treatment, Dyne Technology is here to help you find the most appropriate surface modification technology and equipment to solve your problem. We will be happy to conduct corona treatment trials on your parts to establish the level of surface energy that can be achieved using the corona treatment process. If you have a specific technical question on corona treatment equipment you may find the answer on our FAQ page if not then please contact us.

PLASMA TREATMENT EQUIPMENT
Dyne Technology supplies both vacuum plasma and atmospheric plasma treating solutions to help our customers improve the surface energy of their plastic & rubber components to ensure good bonding of printing inks, paints, adhesives etc. and for the surface cleaning of plastic, rubber and metal parts. Plasma Treating equipment is widely used throughout a diverse range of industries and onto an ever increasing range of substrates. Our growing list of customers includes many in the following industries: medical, electronics, automotive component, cable, ophthalmic, pipe and many more. Through our many years of experience and continuous product development we have become one of the leading suppliers of Plasma Treatment equipment.

What ever your equipment needs are in the field of Plasma Treatment, Dyne Technology is here to help you find the most appropriate surface modification technology and equipment to solve your problem. If you have a specific technical question you may find the answer on our FAQ page if not then please contact us.

FLAME TREATMENT EQUIPMENT
Dyne Technology supplies Flame Treating solutions to help our customers improve the surface energy of their plastic & rubber components usually to ensure good bonding of paints, adhesives etc. Our advanced flame treatment solutions are applied in the automotive component supply industries often using robots to manipulate the flame treatment burner over the part. A wide range of parts can be processed using flame treatment.

What ever your equipment needs are in the field of Flame Treatment, Dyne Technology is here to help you find the most appropriate surface modification technology and equipment to solve your problem. If you have a specific technical question you may find the answer on our FAQ page if not then please contact us.
