Product Introduction
The liquid online sampler is a product developed to address the pain points of reactor sampling in pharmaceutical and chemical production. The power of this product is pneumatic and operates without electricity, making it safe to use in explosion-proof workshops. The contact points of liquid materials are made of PTFE material, which is corrosion-resistant and low pressure resistant! Add cleaning function, after sampling is completed, there is no need to remove the sampler for cleaning, the device automatically absorbs water to clean the pipeline!
