Model ULT - 254 - Prima
Ultra Low Deep Freezer - Touch Screen is used for assessment of physical characteristics of materials like rubber and plastic at very low temperatures. It is a time-tested machine for environmental testing and simulation of severe environmental conditions. Equipped with CFC free refrigerants and air-cooled compressors, performs conditioning procedures required in rubber and plastic industries. The Ultra Low deep freezers come with washable condenser filters and aerodynamically shaped fan for maintaining cooling efficiency.
The internal chamber of the machine is made up of stainless steel and outer body is made up of mild steel. This makes the whole machine highly resistant to rust and increases the shelf life. The strong and sturdy body of the machines reduces the cost of maintenance considerably. The machine has aerodynamically shaped fans that ensure the consistent cooling throughout the machine. Apart from the fans, glass wool insulation is used to maintain the temperature of the chamber. It comes with tower styles 3 coloured alarm to alert the operator. The machine is made in strict accordance with ASTM testing standards. It comes with a calibration certificate traceable to NABL approved laboratories.

Presto Melt Flow Index Tester is used for evaluating the flow properties of molten plastics or resins. The Melt flow Index of thermoplastic materials is defined as the rate of flow (in grams per ten minutes) of extrudates of molten resins through a jet of a particular length and diameter.

The Presto Melt Flow Index Tester - NXG Model is a reliable instrument used for evaluating and analyzing the flow properties of molten plastics or resins. The determination of the melt flow index of plastic materials is an important parameter in the evaluation of its quality.

The Presto Ultra Low Temperature Deep Freezer is equipped with an air cooled compressor and CFC free refrigerators. These systems are installed to provide efficient cooling and consistent flow in the cabinet.

The testing instrument Laminar Air Flow Bench is provided with an HEPA-filtered work area which is essential to maintain dust particles and bacteria free clean air environment.
