Laboratory Freeze Dryers
A laboratory freeze dryer removes moisture from pre-frozen material under vacuum. The process produces a dry product without melting the ice first; the required cycle depends on sample properties, freezing temperature and the target residual moisture.
Bench-top and floor-standing systems
The LaboGene ScanVac CoolSafe 4–15 L range covers compact Basic, Pro, Touch and Superior bench-top configurations. Floor-standing CoolSafe 95/55-80 Superior Bulk and Vial systems are available for larger loads. Chambers, manifolds, shelves, trays and vial stoppering are selected for the specific process.
Key selection parameters
- condenser temperature and compatibility with the product freezing point;
- condenser ice capacity and expected load per cycle;
- ultimate vacuum and a compatible pump type;
- sample format: flasks, trays, chamber, vials or shelves;
- requirements for shelf control, parameter logging and stoppering.
Configuration and related equipment
A freeze dryer operates as a system, so the pump, chamber, manifold and accessories must be compatible. For solvent removal without producing a lyophilized product, see vacuum concentrators. Return to the full freeze-drying and vacuum-concentration range.
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.
