Autosampler Design
With rich functionality
Our Auto sampler executes the following functions:
- Measurement of volume by using a combination of a stepper motor, belt drive and light barrier. The distillation rate is calculated and is used to control the flask heater
- Detection of maximum volume condition, which triggers a bottle changing.
- A second light barrier, installed at a fixed position, detecting the bottle at lifting position.
- A balance weighs the empty bottle and later the filled bottle. By comparing the two weights, the cut weight can be calculated.
- A lifting design with pneumatic cylinder pressing bottle into the outlet device of the distillation line.
- A combination of a pressure sensor and three valves can evacuate the bottle to column pressure level or can pressurize it with N2 after a cut. Bottle change at atmospheric condition without affecting a vacuum of the system. No second pump required.
- An infrared bottle heater keeps a product liquid and allows a proper measurement of volume even by high viscosity fractions.

Intermediate receivers
If you prefer to have an intermediate receiver
We can supply Standard and Large TBP plants with intermediate receivers of sizes ranging from 250 ml up to 5 litres.
