This Dean Stark Apparatus is manufactured in accordance with ASTM D95 requirements, and is mainly composed of a control box and test glassware. The whole machine has a beautiful appearance and is suitable for measuring the water content in petroleum products. This instrument is in a dual form, which can test two samples at a time.
2. Clamp for condensation tube: to hold the condensation tube.
3. Receiving tube: to receive the condensate.
4. Standing rod: To hold the clamps of cross type and clamps for beaker.
5. Round bottom beaker: To hold sample and heat sample on the furnace.
6. Electric furnace: For heating
7. Electric controlling case
* Principles of Water Content Distillation Apparatus
Put the organic solvents and samples insoluble in water in a distilled moisture measurement device. The moisture in the sample evaporates with the solvent steam together. The moisture content of the sample.
* Steps of Water Content Analyzer
Accurate Calculating 2.00 ~ 5.00g Sample → In 250ml of water measurement distillation bottle → Add about 50-75ml organic solvents → connect distillation device → slowly heating distillation → After most of the water is steamed → speed up the distillation speed → The amount of water in the scale no longer increases → read the number
*The advantages and disadvantages of distillation method
Advantage:
1. The heat exchange is sufficient
2. After heating, chemical reactions occur less than the weight method
3. The equipment is simple and easy to manage
Shortcoming:
1. Water and organic solvents are prone to emulsification
2. The moisture in the sample may not be volatilized at all
3. Moisture is sometimes attached to the wall of condensate, causing reading errors
1. Power supply: AC 220V±10%, 50 Hz
2. Power of electric furnace: 1000 W×2
3. Heat controlling type: by a bidirectional silicon controlled rectifier
4. Ambient temperature: ≤35 ºC
5. Relative humidity: ≤85%
6. Total power consumption: not more than 2200 W
