The reactor cover has provisions for venting the off-gases and for reactor loading. The sparger, thermocouple and mixer are removable from the reactor cover to facilitate cleaning. The bottom drain has a special ball valve trapping a minimum volume of reactants, allowing the full reactor charge to be efficiently mixed. The reactants are agitated by twin turbine mixers operated by a controllable variable speed motor. The electrically heated and insulated stainless reactor may be lifted from the stand for easier cleaning.

The reactants’ temperature is controlled by a digital indicating, PID temperature controller. The operating temperature of this reactor is up to 300C. A temperature limit control is provided, which prevents overheating. The airflow is controlled by a precision needle valve and measured by a rotary flowmeter capable of 0 to 10 liters per minute of air. An air pressure regulator also is provided.

This test method is a measure of the relative purity of the various types of liquefied petroleum (LP) gases and helps to ensure suitable volatility performance. The LPG weathering tester results, when properly related to vapor pressure and density of the product, can be used to indicate the presence of butane and heavier components in propane type LP-gas, and pentane and heavier components in propane-butane and butane type fuels. The presence of hydrocarbon compounds less volatile than those of which the LP-gas is primarily composed is indicated by an increase in the 95% evaporated temperature.

This LPG composition apparatus covers the determination of extraneous materials weathering above 38C (100F) that are present in liquefied petroleum gases. The extraneous materials will generally be dissolved in the weathering test of LPG, but may have phase-separated in some instances.

Ayalytical Instruments stainless steel total sediment residual analyzer is comprised of two filtration cells, each of which encompasses a heating (steam) and cooling (water) brass cup with a centered brass disk for support of microfiber filters, and a vacuum circuit with regulation valve. This dual-cell fuel sediment filter design easily increases operator efficiency via the provision of two testing stations. The durable extraction instrument comes complete with 500 mL flask fitted with protection mesh and a vacuum manometer for precise pressure readings, because accuracy is our priority as well as yours.

Designed with procedural efficiency in mind, the conradson carbon residue apparatus is comprised of a Meker lamp withsafety valve for the quick heating of liquefied petroleum gas, and three concentric crucibles: an Innerheat-resistant glazed porcelain crucible with approximate 30 ml capacity; a center Skidmore ironcrucible, flanged and ringed, and fitted with cover; and an external sheet-iron crucible fitted with cover. The carbon residue test apparatus also comes equipped with an insulating ring block for the maintenance of severetemperatures up to 550C, a metal tripod holder with bare Nichrome triangle for the superior stabilityand support of crucibles during testing, and a sturdy, circular sheet-iron hood with stainless steel, easy-clean chimney for the safe diversion of test vapors.

The Evaporation Bath is equipped with 18/8 stainless steel jacket in aluminium block, 5 concentric pre-heating coils with 5 wells connected to the central collector with socket for steam measurer, 5 mobile jets, insulated air gap. Its built-in steam over heater with regulator and condensate discharge valves are designed to help determine the gum content of gasoline. Heating and overheater are controlled by a digital thermoregulator PID with an over-temperature alarm. The gum bath is fitted with a flow-meter wrapped in a protection covering, and steam flow-metric manometer. The overheater for steam can be disconnected.Purchase this steam bath apparatus online.
