1314 Scott Internal Bond Tester|

This instrument measures the energy required to rapidly delaminate a sheet-type specimen. The “Z” directional rupture is initiated by the impact of a pendulum moving at a velocity that exceeds 6000 times the velocity of tensile and/or ZDT testers. As opposed to a simple force and ultimate yield strength measurement, this energy absorption measurement responds to the semi-elastic nature of paper and paperboard. The high speed of the induced rupture makes the test correlate well with real world “Z” direction failures due to impulses, impacts and shocks in printing and converting operations on diverse paper grades as well as synthetic non-wovens.

These failures tend to be millisecond phenomena. The instrument conforms to Tappi Test Method T569, which is an excellent reference for applicability, test details and repeatability data.



1600 Automated Somerville Screen with Doser

For faster and more repeatable laboratory screening of shives, nits, flakes, plastic particles, stickies and other contraries and contaminants in diverse paper pulps, the Model 1600 is an excellent choice. With its easily removable flat slotted screen and computer controlled dosing unit, the instrument can be programmed to process much larger pulp samples than the classical Somerville method.

This makes it useful, not only for analyses, but also for cleaning pulp samples prior to other laboratory testing or refining. The automatic Doser holds up to 500 grams o.d. pulp at 10% consistency, or 250 grams o.d. pulp at 5% consistency, and feeds this into the screen tank at a preprogrammed rate to prevent the formation of fiber networks that would impede and slow the screening process. Because the sample feed, water additions, screen backflush and draining are computer controlled, it is not necessary for the operator to remain in attendance during the screening cycle.

Even the initial water fill is rapid and automatic.




1500 Somerville Screen Separator

For ease of operation the Huygen Model 1500 features a manual ball valve fast-fill system, quick-release screen tank latches, and two button electronic controller.

The standard 20 minute screening cycle time can be extended by simply pushing the START button a second time.

This is useful when manually adding several small samples to avoid the formation of fiber networks.
The DC motor that oscillates the backflush diaphragm has an electronic speed controller to provide a consistent backflush rate.

As with the Model 1600, the removable flat screen plate, screen tank, weir tank and quick- disconnect calibrated nozzle are all 316 stainless steel. Also, the entire instrument is mounted on a sturdy polypropylene cart.

For automatically processing larger samples of pulp with computer programmable cycle and pulp addition (dosing) times, three selectable oscillation/backflush speeds, auto-fill and automatic drain functions, see the Model 1600 above.



2100 Digital Bench Opacimeter

This instrument measures the opacity of products such as paper, plastic sheets containing colorants and clear plastic films and sheets.

By using Huygen’s Photronic® detector with Viscor® filter, it offers the same color response as the human eye, but is much more sensitive to opacity or clarity/transmission/haze than a human observer.

By the contrast ratio technique (using a white body calibrated reflector and a black body/light trap), the effect of varying gloss is removed from the measurement.

The instrument’s greater and more repeatable optical sensitivity makes it useful for controlling colorant or opacifying agent additions to the product---thereby generating a more uniform product at lower cost.

Its coated and hooded optics produce extremely low light scattering error and excellent linearity making the instrument suitable for accurate transmission measurements on thin, clear plastic films.

The unit conforms to Tappi Test Method T425 and is available factory configured for ASTM D1003 haze measurements.



Model 2300 Strip Opacimeter

For faster testing of single samples or multi-points on strip samples, this instrument offers single pushbutton operation. In addition to the computerized display and statistics, the calibrated white body and black body/ light trap are controlled by the internal AV-3 computer and their movement in two planes is automated.

This stainless steel cased instrument “clamshells” open to permit inspection of the backings and optics. Its accuracy is equal to the Model 2100 and its measurement speed minimizes the possibility of lamp generated heating or drying of the sample. The unit conforms to Tappi Test Method T425.
