Manual Atmospheric Distillation Apparatus for Petroleum Products

What is the Manual Atmospheric Distillation Apparatus for Petroleum Products?

A manual atmospheric distillation apparatus boils a 100 mL petroleum sample in a standard flask while the operator regulates heat and reads the condensate volume and temperature by eye. It suits laboratories running occasional ASTM D86 or ISO 3405 tests on gasoline, kerosene, diesel and naphtha at low capital cost.

Overview

The manual apparatus consists of a 125 mL distillation flask, a shielded heater with a manually adjusted power control, a condenser tube in a cooling bath, a graduated 100 mL receiving cylinder and a temperature sensor positioned at the flask neck. The operator controls the heat input to meet the initial boiling rate of 5 to 10 minutes from start to first drop and then 4 to 5 mL per minute, reading the temperature when the initial boiling point occurs and at recovery volumes specified in the method. A refrigerated or ice bath cools the condenser for volatile samples. Results depend on operator judgment for volume reading, heating adjustment and timing, so training is important. Barometric pressure is recorded manually and used to correct observed temperatures. The instrument has simple maintenance needs and uses standard replaceable glassware, which suits basic laboratories.

How does it work?

A distillation tester heats a measured sample in a flask so that it boils and the vapor passes through a condenser held at a controlled temperature. The condensate is collected in a graduated receiver, and the vapor temperature is recorded at the initial boiling point and as specific volumes are recovered, such as 5, 10, 50, 90 and 95 percent, up to the final boiling point. The heating rate is adjusted to keep the distillation rate within method limits. Apparatus includes the flask, heater, condenser bath, receiver cylinder and temperature sensor. Automatic models add level-tracking sensors and refrigeration. Vacuum methods reduce pressure so heavy oils distill without thermal cracking, and simulated distillation uses gas chromatography to infer boiling distribution from retention time. Barometric correction is applied to atmospheric results.

What are the key features?

• Standard 125 mL flask and 100 mL receiving cylinder
• Manually adjustable shielded heater
• Cooling bath for condenser with temperature control
• Flask support boards with specified hole diameters
• Digital or glass thermometer at flask neck
• Low-cost apparatus with simple maintenance

What are the technical specifications?

A typical manual atmospheric distillation apparatus for petroleum products configuration offers test method of ASTM D86 manual, ISO 3405, GB/T 6536, sample volume of 100 mL, temperature range of 0–400 °C, flask volume of 125 mL, receiver of 100 mL graduated cylinder, 1 mL divisions and condenser bath of Ice or refrigerated, 0–60 °C. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Manual Atmospheric Distillation Apparatus for Petroleum Products is used in kerosene and diesel testing, solvent and naphtha boiling range, teaching laboratories and occasional fuel checks. Across the wider Distillation Testers class, laboratories also deploy it for gasoline and diesel volatility control, jet fuel and kerosene specification testing and naphtha and solvent boiling range.

Which standards and certifications apply?

Relevant standards and methods include ASTM D86, ASTM D1160, ASTM D2887, ASTM D7345, ISO 3405, IP 123, GB/T 6536 and IEC 61010-1. Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Install distillation testers in a ventilated area with stable room temperature, because ambient conditions affect condenser and receiver temperatures. Use properly dimensioned flasks, supports and baffles, since small changes in geometry alter results. Calibrate temperature probes and level sensors against traceable standards, and run check samples such as reference toluene or certified reference fuels at defined intervals. Check refrigerated baths for coolant level and temperature stability. Clean condenser tubes regularly to prevent residue carry-over, and inspect glassware for cracks before heating. Record barometric pressure and apply corrections where the method requires. Dispose of distillation residues as flammable waste. For vacuum systems, verify leak tightness and pressure gauge calibration before each series.

How do I select the right Manual Atmospheric Distillation Apparatus for Petroleum Products?

Choose the manual apparatus for occasional testing or training where labor cost is low and a few samples per day are needed. It is less repeatable than automatic units. In an RFQ specify the ASTM D86 sample groups, cooling bath type, thermometer or probe requirements, and whether glassware sets are included.

How does it compare with other Distillation Testers variants?

Begin with the method and product type. ASTM D86 atmospheric distillation covers gasoline, diesel, kerosene and naphtha, while heavy oils that decompose at atmospheric boiling points need vacuum distillation under D1160. Decide between manual and automatic operation: manual apparatus is inexpensive but needs constant attention and is operator-dependent, whereas automatic units control heating profiles, track volume electronically and apply corrections. Small sample volumes or many samples favor micro-distillation, and full boiling distributions from small samples favor simulated distillation by gas chromatography, which needs a different skill set. Check condenser cooling capability, since light gasoline requires near 0 °C baths, and confirm the apparatus supports the sample groups you test. Also compare footprint, fume extraction needs and glassware replacement costs.
