Product Q&A

Q:How should I choose -60 C, -85 C or -105 C?

-60 C is normally selected for routine aqueous samples. Choose -85 C for many solvent-containing or lower-eutectic samples, and -105 C for very low eutectic-point samples or dilute methanol/ethanol mixtures. The condenser should normally be 10-15 C colder than the sample eutectic or collapse temperature.

Q:Are the cabinet dimensions the same for all condenser temperatures?

No. The -60 C version uses a more compact cabinet. The -85 C and -105 C configurations use a larger refrigeration cabinet. Request the configuration drawing before ordering.

Q:Which drying accessories can be supplied?

Options include clear drying chambers, trays, vial shelves, manifolds, flasks, ampule adapters, manual stoppering chambers, sample probes, vacuum regulation and remote monitoring.

Q:Can Pioneer 4L process peptide and protein samples?

Yes. Pioneer is suitable for laboratory formulation screening and small-batch peptide, protein and biotechnology samples. The correct condenser temperature and cycle parameters depend on the formulation and critical product temperature.

Q:Which vacuum pump should I select?

A rotary-vane pump is suitable for routine aqueous work. For solvents or acids, request a chemically resistant pump configuration, corrosion-resistant condenser option and appropriate secondary trap.
