DETERMINES GEL TIME AT TEMPERATURES UP TO 350 DEGREES F
The Hot Pot line of Gel Timers incorporates all the quality features, simple operation, and accuracy of our original Gel Timer– and more! The Standard Hot Pot with a simple rheostat temperature controller. It uses a Teflon-lined aluminum pot and gel time can be determined at temperatures up to 350 degrees F.

SIMPLE TO OPERATE!
Set the control to the desired test temperature. Pour the material sample into the throwaway aluminum cup. Place the cup in the Hot Pot Gel Timer well, insert the throwaway wire stirrer and set the counter to “zero”. Switch on. When gelation occurs, read gel time and discard the cup and stirrer. The Hot Pot Gel Timer can be left on the full setting overnight without harm; however, unattended testing using heating capability is not recommended.

NO MESS! NO TOOLS REQUIRED ! NO CLEANUP!
These durable gel timers use inexpensive, disposable wire stirrers and aluminum cups. No special skills are required.

Melt Flow Indexers are affordable bench top instruments that measure the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of a wide range of thermoplastic raw materials (granulate). Melt Flow Index Tester is manufactured as per ASTM D–1238 to measure the flow rates of thermoplastics by extrusion plastometer. This test indicates the uniformity of the flow rate of the polymer.

Significance:
The melt flow index tester helps gauge the composition and consistency of plastics, rubber, lubricants and numerous other liquid and molten substances.

Standard Compliance:
ASTM D1238 and D 3364
ISO1133
GB/T 3682

COF is used in a variety of materials from lubricants, to films to household items (ceramic tiles) to determine the frictional characteristics of a material. It is generally determined to be the easy by which two surfaces (often of different materials) slide against each other.

Significance:
Coefficient of Friction (COF) is the maximum value of the frictional force divided by the normal force. The dimensionless value of the COF is the ratio of the force required to slide the surface to the force perpendicular to the surface. A low COF indicates that the surfaces are smoother, e.g. less resistant to a sliding motion. Polymers used for film production are usually tested dry against a sled with a calibrated load.

Standard Compliance:
TAPPI T-815
ASTM D202



DETERMINES GEL TIME EASILY AND ACCURATELY!
The Digital Gel Timer easily determines the gel time of resinous plastics, adhesives, drying oils, two component elastomer and paints at ambient temperatures– A simple device for a simple test. A low-torque, synchronous motor rotates a specially shaped stirrer in the catalyzed resin or elastomer. As gelation occurs, drag exceeds torque, which stops the clock and activates a flashing lamp. Gel Time will be shown in minutes and seconds on the digital display.

SIMPLE TO OPERATE!
Place the material sample in a paper throwaway cup. Insert the throwaway wire stirrer, set the counter to “zero” and switch on the unit. When gelation occurs, read the time and discard the cup and stirrer. The motor can remain stalled overnight without damaging the unit.

NO MESS! NO TOOLS REQUIRED! NO CLEANUP!
This durable gel timer uses inexpensive wire stirrers and paper cups. No special skills are required. Designed and constructed in the USA to offer long and useful laboratory or shop service.

The falling dart impact tester determines the impact resistance of plastic film by the free falling dart method. The apparatus establishes the energy required to tear film specimens under specified conditions of impact of a free falling dart. The energy is expressed in terms of the weight of the dart when 50% of the film specimens fail under the conditions specified. The sample is held down by a pneumatically operated clamp. A range of weights is provided to enable tests to be performed on various film thicknesses. The working range of the weights is established by finding the weight that will just break the sample film.

Significance:
The unit employs a dart, with a 38mm diameter hemispherical head, dropped from a height of 660mm. This unit may be used for films whose impact resistance requires masses of approximately 50gms to 2 kg to fracture them.

Standard Compliance:
ASTM D 1709 Method B : Total Energy Impact of Plastic Films The Falling Dart Impact Kinetic energy option , Is where the existing unit is mounted on top of the Kinetic energy option, where there is a catch box and two switches measuring the fall time difference which is displayed on a instrument panel as time.

Test Method B: Dart Head - 50mm +/- 0.8mm; Drop Height - 1.50m +/- 0.03m
Weights supplied - 2 x 15g, 8 x 45g, 8 x 90g

Test Method A: Standard Flexible films

The Hot Pot line of Gel Timers incorporates all the quality features, simple operation, and accuracy of our original Gel Timer– and more! The StablTemp Hot Pot Gel Timer incorporates an electronic proportioning control which regulates the set temperature with virtually no drift or variation. It uses a Teflon-lined aluminum pot and gel time can be determined at temperatures up to 350 degrees F.

SIMPLE TO OPERATE! 

Set the control to the desired test temperature. Pour the material sample into the throwaway aluminum cup. Place the cup in the Hot Pot Gel Timer well, insert the throwaway wire stirrer and set the counter to “zero”. Switch on. When gelation occurs, read gel time and discard the cup and stirrer. The Hot Pot  Gel Timer can be left on the full setting overnight without harm; however, unattended testing using heating capability is not recommended.
