Hornblende (Amphibole Mineral) Specimen - Hand Sample - Approx. 3" ag sci and industrial processes

and industrial processes

Used as the red-rail counterpart to the 750mm black 2mm lead

this spirometer data-logging sensor reads airflow through an integrated tube and calculates lung volume in liters across ±10 L/s of breath flow

The concave dishes work well as lids for flasks and beakers

free of magnetic-core saturation effects for AC circuit

Hornblende (Amphibole Mineral) Specimen - Hand Sample - Approx. 3" ag sci and industrial processesHornblende sample approximately 3" in size Useful for students to study as an example of two plane, non perpendicular cleavage Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Ideal for use in lessons on Bowen's reaction series Specimen comes in clear labeled and barcoded bag for ideal storage Hornblende is part of a group of minerals known as amphiboles.
