TBP - Reflux Divider Design
Leakage free operation
The benefits at a glance
- No glue effect because of condensation of waxy fractions.
- Pneumatic driven plunger with O-Ring seal.
- Leakage free construction.
- Fast O-Ring changing.
- Teflon made vacuum throughput.
- Plunger rod can be made of PEEK or ceramic. No more corrosion of stainless steel.
- No grinding required.
- Different head temperature sensors available: Stainless steel, Teflon coated, Glass.
The second highlight is the pneumatic driven reflux divider. This replaces the old fashioned reflux divider design which uses a glass plunger falling into the valve seat; also made of glass. This type of construction will/can leak within a short time.
Therefore, they have to be grinded frequently and the grinding needs someone with experience in working with glass and takes a great amount of time. Our reflux divider has a stainless steel or ceramic rod with an O-Ring at the bottom. This O-Ring is pressed into the valve seat with a force of approximately 1 kg and seals the valve with it’s soft surface.
This construction offers a leakage free operation. The reflux divider can be dismantled for O-Ring replacement, which takes less than two minutes. On average, this job has to be done after 25 distillations (using inexpensive Viton sealing ring) or after 100 distillations (using Kalrez sealing ring).
