Rotary Evaporator

Rotary evaporators are used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.

Product Features

A rotary evaporator (rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The primary purpose of distillation is separating a particular mixture into components that are based on their respective volatilities via evaporation and condensation.

Features of our rotary evaporators include:

  • Capacity: 1L, 2L, 3L, 5L, and 10L to 50L meet the needs of different sample volumes
  • Heating bath material: stainless steel or aluminum alloy for durability and stability
  • Condenser type: vertical or diagonal for efficient cooling and solvent recovery
  • Evaporating flask material: borosilicate glass or GG-17 high borosilicate glass for chemical resistance and transparency
  • Rotating speed range: 0-120rpm for precise control of evaporation rate
  • Motor power: 40W for smooth and reliable operation
  • Temperature range: ambient to 99°C for accurate temperature control
  • Vacuum degree: 0.098Mpa for efficient solvent removal

How a Rotary Evaporator Works

  • A rotary evaporator works by heating a sample in a flask under vacuum conditions to remove the solvent from the sample. The main components of a rotary evaporator are:
  • A motor unit that rotates the evaporation flask or vial containing the user’s sample.
  • A vapor duct that is the axis for sample rotation, and is a vacuum-tight conduit for the vapor being drawn off the sample.
  • A vacuum system, to substantially reduce the pressure within the evaporator system.
  • A heated fluid bath (generally water) to heat the sample.
  • A condenser with either a coil passing coolant, or a “cold finger” into which coolant mixtures such as dry ice and acetone are placed.

 

The process of rotary evaporation involves:

  • The sample is placed in a flask and rotated under vacuum conditions.
  • The solvent evaporates and is drawn off via the vacuum system.
  • The solvent vapor is condensed and collected in a separate flask.

Sanitary grade of SUS304/SUS316L Stainless Steel Vendor: Shanghai Bao Steel Group Corporation or equivalent supplier.

In order to keep the raw materials organized and make sure proper material will be used, we insist asking the material vendor to provide original material test report. Also, we will do in-coming tests to ensure the material is qualified:

  • Metal spectrum analyzer
  • Thickness gauge
  • Roughness detector

All designing, manufacturing and inspection processes are performed according to GB150-1998. ISO9001 Quality Management System Standard will also be applied throughout the entire manufacture process.

Yes, with our certified workshop and excellent welding technics, we can provide you with high quality ASME or PED pressurized equipment.

As multiple tests and inspections are required, lead time of such equipment is longer than normal pressure equipment, it usually takes 18 to 20 weeks to finish.

Plasma welding machine imported from Germany will be used for tank longitude and girth welding and fillet welding to make sure the welding seam smooth and even.

Also, GTAW welding technology will be applied, inert gas concentration is 99.999%. Different welding wire ER316L or ER308 will be applied for different material of SS plate.

For particular circumstances, electric-arc welding will be applied. Welding material used for:

S304-S304: A102; S316L-S316L: A022; Different SS: A302.

Welding seam between jacket and vessel shall be NDT inspected according to JB4730-94 to ensure the impermeability and long service life.

For single tank, it takes around 3-5 weeks to deliver.

For integrated systems, it normally takes 18 to 20 weeks to deliver.

ASME/PED certified equipment will take 18 to 20 weeks

You are welcome to contact us for details if any needs.

Yes, customization order is acceptable.

You may send over the requirements, we will realize your design and provide you with the most cost-efficiency solutions.

Plastic wrap film should be applied around the entire equipment.

Electrical parts should be disassembled and packed in crates if possible, otherwise it should be fully protected from water or any kind of potential damage in shipping.

Tank will be put down and sitting on a CS frame support, steel wire will be used for fasten tank to support. Rubber should be applied to where steel wire is touching the equipment.

When fixing the equipment in container, multiple fixing belts and/or steel wires should be used to make sure no movement of equipment.

should be used to make sure no movement of equipment

Yes, we will.

Equipment will be thoroughly washed before packing. Water used for washing should not have chloridion content more than 25mg/L to avoid damage of stainless-steel surface. Water stains must be cleaned once washing is finished.

Normally we will ship the equipment by sea due to the weight of it.

Air shipping is also an option, but it will cost more.

It depends on your choice.
