Vacuum Concentrators
A vacuum concentrator lowers the solvent boiling point and accelerates its removal from samples. In centrifugal systems, rotation helps keep material in the tubes and reduces foaming or bumping during concentration.
LaboGene ScanVac and ScanSpeed systems
- MaxiVac Alpha and Beta — automated systems for different volumes and vacuum-concentration tasks; the Beta configuration also supports low-temperature processing and freeze drying;
- MiniVac Alpha and Beta — compact centrifugal concentrators for smaller samples;
- ScanSpeed 32 and 40 — centrifugal systems whose capacity depends on the selected rotor and tube format.
Selection criteria
Important factors include solvent type and quantity, material compatibility, initial and final volume, tube format, rotor capacity, temperature regime, required vacuum and compatibility with the pump and trap. Vapours that may damage the pump require an appropriate cold trap or other protective component.
Vacuum concentration or freeze drying
Concentration is used to reduce sample volume or remove solvent. If the aim is a dry, stable product from pre-frozen material, consider laboratory freeze dryers. All related components are grouped under freeze drying and vacuum concentration.
What to compare before ordering
| Criterion | What to verify |
|---|---|
| Process | Method, materials, required outcome and constraints |
| Working area | Capacity, accessory dimensions, sample or operator count |
| Utilities | Power, gases, water, vacuum or exhaust as required by the model |
| Acceptance | Documentation, commissioning checks and service access |
Questions before selection and procurement
Is a matching headline specification enough to compare models?
No. Compare the full configuration, operating conditions, accessories and method constraints. Maximum figures may apply only under specified loads.
How should room readiness be checked?
Provide installation dimensions and available utilities. Compare them with the model manual before agreeing the supply configuration.
What belongs in the specification?
The main instrument, modules, holders, consumables, documentation, installation and acceptance checks. List optional equipment separately.
What is needed to compare quotations?
A technical specification and an equivalent equipment list for each option. Specify quantity, installation or use location, compatible accessories and documentation requirements. This supports comparison of the complete cost of the required solution.
Configuration and documentation
Record the exact model, version, standard equipment and optional items in the quotation. Request the manual and specification with the conditions under which performance figures are determined. Agree procurement documentation, availability, delivery, warranty and service work for the specific supply.
