Vortex Vacuum Concentrators with Sample Heating and Cooling Features




Concentrator Brochure
Vacuum Concentrator


The Hettich Vortex Vacuum Concentrator (HVC) is designed to remove solvents from samples while under vacuum. Unlike traditional centrifugal evaporation methods, the HVC uses a vortex motion with infrared heating and an intelligent vacuum pump to remove solvent from samples.

Diagram of how HVC works during centrifugation


The picture demonstrates the Hettich Vacuum Concentrator with sliding lid (robot friendly) and the loading of the heated base plate with attached universal rack. The rack will then sit in the 316 stainless steel chamber attached via its magnetically coupled feet. After the rack is loaded the lid will close and the evaporation process will begin.

Sample Heating/Cooling

The HVC offers 3 types of heating for constant and consistent sample temperatures.

  • Ceramic infrared heaters built into the lid of the HVC
  • Interior chamber wall heating to prevent condensation
  • An optional base plate heater with a range of 20 to 40 °C.
Evaporation process in the HVC chamber

The heating is activated by a temperature probe inside the evaporation chamber that is set by the user to the desired sample temperature. As evaporation occurs and the sample cools and the heating is activated to maintain the sample set temperature.


The HVC was designed to be robotic friendly with its RS232 connectivity, programmability and ability for robotic arms to have easy access to the sample. The lid of the HVC slides to the left completely exposing the sample chamber, this provides easy interfacing for robotics.

Sample Racks & Base Plate

A variety of racks are available for the HVC to accommodate both microplates, tubes and microtubes plus any combinations of the above. A number of custom accessories are available such as to purge inert gases onto a microplate.

Quality Construction

Utilizing the most current technology, Hettich manufactures its products to meet the latest in industry quality standards. All Hettich products go through rigorous in-house testing. Product quality tests are supervised by the major governing bodies (i.e. TUV) to ensure the highest level of safety in manufacturing. The metal components that make up our products go through a variety of stress tests and are studied to determine risk and product life cycle.

PoleStar cold trap for Hettich Concentrator

The PoleStar cold trap has been designed to meet the most demanding requirements of the evaporation process and to ensure the highest flexibility for the condensation or solvent recovery of solvents.
The closed loop cooling system cools the cooling coils down to –50°C. This ensures that all solvents condense on the coils protecting the vacuum pump. The cooling coils plus the chamber is PTFE coated for maximum chemical resistance.

Intelligent vacuum pump for HVC, the PC 3000 series diaphragm pump The intelligent vacuum pump used with the HVC is a diaphragm pump with variable speed and a minimum vacuum of 0.6 Mbar. The pump is extremely quiet compared to other systems on the market.

The pump measures vapor pressure and adjusts its speed to the parameters chosen by the HVC.

By linking programs in the HVC and utilizing the features of the vacuum pump complex solvent mixture can be evaporated to dryness.

The pump has three modes of operation, the two that are mainly used by the Hettich Vacuum Concentrator are the PREC mode which will pull a vacuum to a desired mbar at a specified speed and the AUTO mode which measures the vapor pressure and adjusts the speed automatically.
