Congratulations! The Ju Tong brand fully automatic constant volume and quantitative nitrogen blowing instrument has been successfully delivered to Sichuan BlackRock testing technology for use. The nitrogen blowing instrument series of Hangzhou Jutong Electronics Co., Ltd. is a main product with independent research and development, complete varieties, and stable quality. This series of product models is diverse and can meet the needs of different units and industries for sample concentration processing. After consulting and comparing the testing technology of Sichuan BlackRockchoiceJuTong's fully automatic constant volume and quantitative nitrogen blowing instrumentSignificantly increase the concentration rate. At the same time, the device uses its own exhaust fan to directionally discharge the evaporated exhaust gas through the exhaust pipe, allowing the nitrogen blowing concentration device originally placed in the ventilated kitchen to be safely installed on a general experimental platform. Not only is it easy to move, but it also saves laboratory costs. The JuTong fully automatic nitrogen blowing concentrator can concentrate single or multiple samples simultaneously without the need for manual supervision; This model uses multiple optical sensors to monitor the concentration process of each sample. When the evaporation concentration reaches the preset volume, the system automatically stops the nitrogen purging of the corresponding channel and gives an alarm prompt. The entire concentration process does not require manual supervision; It is a sample pretreatment device in the laboratory.
