详情描述

Broadly used in environmental protection, scientific research, and industries such as petrochemicals, metallurgy, and dyeing and printing. Used for pretreatment equipment for soil hexavalent chromium.

Applicable Standard: HJ 1082-2019

"Determination of Hexavalent Chromium in Soil and Sediments – Alkaline Extraction-Flame Atomic Absorption Spectrophotometry"


Instrument Features:

1. The heating material is full aluminum with an anodized surface treatment. It features single-hole, single-cup heating with a temperature difference of ±1°C between heating holes, which is smaller than the temperature difference in older magnetic stirrers, resulting in lower error.

2. This magnetic heating stirrer does not require a temperature sensor, eliminating the interference that older magnetic stirrers cause by placing the sensor inside the beaker.
