SGE syringes with a range of capacities, termination types, and numerous needle sizes for a wide range of applications. This selection guide explains the SGE syringe features and how to select the ideal syringe for any application.

 

The Helipath Stand is designed for measurement of non-flowing substances such as gels, pastes, creams and putty using a T-bar shaped spindle.

The Brookfield Helipath™ Stand, when used with a suitable Brookfield Viscometer/Rheometer fitted with a special T-bar type spindle, will permit viscosity/consistency measurements in relative centipoise values for materials having characteristics similar to paste, putty, cream, gelatin, or wax.

Many substances, because of the nature of their yield values, have been considered unsuitable for viscosity or consistency measurements with rotational viscometers. Any rotating spindle, be it cylinder, disc, or paddle, will create a channel in such substances and after a very short time exert a negligible and meaningless torque on any sensing device. This effect also occurs with materials that have a gel structure.

Paint dyes, lithographic inks, and many other substances are thixotropic in that their structure is broken down and their viscosity is decreased when subjected to internal shearing. While no rotating spindle will ever spin freely in such materials, the torque required to produce this motion will become less as the period of internal shearing lengthens. The study of such data can lead to difficulties and require rigid testing procedures for QC.  Other materials, notably pastes and creams, show a combination of the two effects listed above. They will show a yield value as well as a change in relative viscosity/consistency with time.

The Brookfield Helipath™ Stand is designed to slowly lower or raise a Brookfield Viscometer/Rheometer so that its rotating T-bar spindle will describe a helical path through the test sample. By always cutting into fresh material, the problem of channeling or separating is eliminated and meaningful viscosity/consistency measurements can be made. The automatic reversing feature of the Helipath™ Stand allows measurements to be made over a variable period of time.

FEATURES BENEFITS :

• Designed for viscosity/consistency measurement of gels, pastes, creams, putty, gelatin and other non-flowing substances.
• A Brookfield Viscometer or Rheometer is mounted on the Helipath drive motor and a T-bar spindle is attached to the viscometer using a special coupling. The drive motor slowly lowers or raises the viscometer so that the T-bar spindle creates a helical path through the test sample thus eliminating the problem of "channeling".
• Compatible with standard Brookfield Viscometers and DV3T Rheometers
• Simple to set up and clean
• Provides a solution for hard-to-measure materials
• T-Bar Spindles
• Can be used with any standard Brookfield Viscometer and is supplied complete with a set of six T-bar spindles and a special coupling.

EZ-LOCK :
This spring-loaded sleeve design is perfect for the busy lab and/or multiple user environments  How does it work? Simply attach the EZ-Lock Spindle Coupling to a spindle (see insert above) and then slide the spring-loaded knurled sleeve up. Insert the spindle and then slide the sleeve back down. That's it! Changing spindles has never been quicker or easier...making this the perfect option for multiple testing environments.

The EZ-Lock System can be purchased as an option when ordering new instruments with standard spindles for standard viscometers and rheometers.

EZ-LOCK RETROFIT :
EZ-Lock is also available for use with your favorite Brookfield accessories such as Thermosel, Small Sample Adapter, Enhanced UL Adapter, UL Adapter, and DIN Adapter. Special brackets are required to accommodate the length of the EZ-Lock system.  Below are the part numbers of the special brackets needed.
