Easy-to-clean design, the main body is made of durable glass fiber-reinforced polybutylene terephthalate, which is heat- and chemical-resistant. Combine baths and magnetic stirrers (sold separately) for excellent temperature uniformity and stirring action. Typical applications include protein digestion and polymer research.
