Temperature controlled presses.
LTP-250 Micropress

The LTP-250 MicroPress is a miniature thermal pneumatic press designed for the curing of SMC, BMC, epoxies, polyesters, polystyrenes, polyurethanes, silicones, laminates and other polymeric materials. Providing a portable, easily operated platform to reproduce the time-temperature-pressure processing profiles of most polymers, the LTP-250 MicroPress has independent temperature control of both upper and lower platens and can operate in either isothermal or ramp-and-hold modes.

The LTP-250 MicroPress can be controlled manually or with the Lambient Technologies CureView software. When used with any of the Lambient Technologies dielectric sensors, the LTP-250 MicroPress becomes a complete testing station for dielectric cure studies.

Parallel Plate Cell

For use with our instruments or an LCR meter.
LT-4203 Parallel Plate

The LT-4203 Parallel Plate Test Cell is designed for measuring the AC loss characteristics and permittivity of solid laminates and panels per ASTM Standard D150-98, and implements the guarded electrode (three terminal) measurement preferred as the referee method.

The standard sense electrode is 6.0 cm in diameter and the electrode separation may be adjusted to accommodate various sample thicknesses. A removable micrometer head permits measurement of electrode separation before testing. The 1.0 cm wide guard electrode eliminates fringing electric fields around the sense electrode for accurate calculation of test cell capacitance. Both electrodes are surrounded by a grounded frame which acts as a Faraday cage to reduce pickup of external electrical noise.

Maximum operating temperature of the LT-4203 is 150 °C, allowing measurement of dielectric properties at elevated temperatures. Modification of the LT- 4203 for operation up to 200 °C is available upon request.

The LT-4203 Parallel Plate Test Cell may be used with either the Lambient Technologies LT-451 Dielectric Cure Monitor or generic LCR meters. When used with the LT-4203, the LT-451 can test samples with thicknesses between 0.025 cm and 0.50 cm with optimum accuracy.
