3L Rotary Evaporator - Manual LIft

Product Description:

SINOBRO TECH Rotary evaporator (or Rotavapor/ Rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.

Rotary evaporator makes the material be rotated to thin film, under the constant temperature and negative pressure. It can be evaporated efficiently, very suitable for the crystallization, separation and solvent recovery for heating sensitive materials. Some models can also be used for reflux extraction. It is an important equipment for scientific research and production in Biology, Medicine, Chemical and Food Industry.

Rotary Evaporator Parts:

PID digital controller

The rotary bottle glass is made of first grade high borosilicate glass, and the three high temperature annealing ensures that the heating is fast and balanced.

Using long Magnesium Oxide layer heating wire and stainless steel 304 heating pipe, water and electricity are separated.

PID digital temperature control, accurate control, real-time display.

Sealing device

The PTFE sealing body is made of customized precision fluoroadhesive oil and processed by numerical control technology four times.

Ensure airtightness up to -0.1Mpa, high durability and long service life.

The whole seal uses glass to contact with PTFE, and has good acid and alkali resistance and good vacuum degree.

The connection is fixed with nylon nut to facilitate installation and dis-assembly.

Speed rotating device

The motor is equipped with gear reducer, which is 3 times the torque of the original motor. It can enlarge the torque by 5 times in a short time. It has the characteristics of small volume, high power, fast heat dissipation and so on.

Using stepless speed regulation, with the real-time speed display, the bottom is equipped with an aviation plug connected to the stirring motor, and the function of screw locking to prevent bad contact;

The equipment is also equipped with overload protection function to avoid the overload of governor caused by the thick material.

Collection system

The collecting glass is made from the first grade high boron silicon glass, and the three high temperature annealing, strong and safe.

The collecting glass can be collected continuously without stopping the machine.

The bottom of the bottle is collected with PTFE discharge valve to ensure no leakage, acid and alkali resistance.
