Frequently Asked Questions
Yes, samples in serum bottles or vials should be stoppered under vacuum to maintain sample integrity, prevent contamination, and ensure reliable analysis results, especially for sensitive laboratory or research applications.
Aqueous samples: -50°C Aqueous/solvent samples: -84°C (e.g., small amounts of acetonitrile)
For North America, the correct plug type is typically 115V with a standard two or three-pronged plug. If you’re operating in other regions, ensure the power supply matches the local voltage requirements (230V for many international locations).
If your samples contain corrosive substances or acids, using an acid-resistant PTFE-coated collector is essential to prevent material degradation and ensure optimal sample preservation, maintaining the integrity of both the sample and the equipment.
Additional features like a purge valve, mini chamber, or shell freezer can enhance performance, especially for specific sample types. These options improve control over environmental conditions, ensuring better preservation and efficiency during processing.
