Lab spatulas and spreaders come in metal, PTFE, polypropylene and other plastics. Laboratory grade stainless steel and plastic spatulas are ideal for transferring your samples, scraping or applying powders.
- Stainless steel spatulas resist boiling water, acids, bases, and most solvents.
- Polystyrene spatulas are disposable, which helps prevent contamination in sensitive applications and are useful in lyophilization.
- Polyamide spatulas are solvent-resistant but is damaged by acids and oxidizing agents.
- PTFE (sold or coated) spatulas are highly resistant to most chemicals.
