**FOR IMMEDIATE RELEASE:**

*Merrifield, Va. – Apr. 29, 2011*

 

**CSC Scientific Announces Replacement for Discontinued Fisher Tensiomat****© ****Tensiometer**

 

CSC Scientific, a manufacturer and distributor of **surface tension analysis products,** announces a replacement for the now-discontinued **Fischer Scientific Tensiomat©**** surface tension tensiometer**. Any user who requires a new instrument or a repair of an existing instrument should contact us. The CSC Precision Tensiometer and Interfacial Tensiometer models are direct replacements.

 

After long deliberation, **Fisher Scientific has discontinued its Tensiomat****©** surface tension tensiometer, which has been produced for decades.

CSC Scientific has produced **tensiometers** since the 1950s. These perform the same tests and are a direct replacement for the Tensiomat©. The CSC models are the called the [**Precision and Interfacial Tensi**](https://www.cscscientific.com/surface-tension/tensiometer/)

[**ometers**](https://www.cscscientific.com/surface-tension/tensiometer/). The difference between the CSC tensiometers is:

**Precision Tensiometer** - Readings are obtained from an upward pull through the sample.

**Interfacial Tensiometer** – Readings can be obtained from an upward pull or a downward push

The **CSC Interfacial Tensiometer** is needed when calculating interfacial tension between a less-dense fluid and a heaver one located below the interface. The ring is rigidly attached to the measuring arm to obtain a downward measurement. We also **recommend the Interfacial Tensiometer when the tested material is a thick liquid.** This makes it easier to set up the ring below the liquid surface.

A key component of any of these instruments is the **duNouy ring**, which is a precision device made of a platinum-based alloy. The rings are manufactured utilizing special forming and welding techniques unique to this alloy and ***can be used with existing Fisher Tensiomat******© units. ***

CSC Scientific has produced these rings for more than 50 years.

*We offer long-time users service and repair of these discontinued Fisher Scientific Tensiomat©** units and will do so as long as replacement parts are available*. The **duNouy rings** are fragile and are frequently dropped, misshapen or broken. CSC Scientific has maintained a ring repair service for many years and will repair Fisher-supplied rings..

**Either the CSC Precision or the CSC Interfacial Tensiometers can be used as direct replacements for the Tensiomat©**.. Contact CSC Scientific to determine the correct tensiometer for your application via email [service@cscscientific.com](mailto:service@cscscientific.com) or phone 703-876-4030.

These CSC Instruments are available from several of the laboratory supply dealers or directly from the [CSC Scientific Company.](https://www.cscscientific.com/)
