42 chemistry Airtight reaction chamber Item 011 002 Carry out chemical reactions with gas release Transparent : easy observation of chemical reactions Can be connected to pressure sensor, gas trap, C02 cartridge Security valve to avoid overpressure Airtight reactor allows students to carry out chemical experiment (except combustions) releasing product at gaseous state. Thanks to its transparency, students can observe the chemical reactions inside the reactor. The cover is equipped with two airtight outlets to connect various instruments (pressure sensor, gas trap, CO2 cartridge…) and with a security valve to avoid overpressure. A reagent holder has been designed to put reagents inside the container and to trigger the reaction after it has been closed. Features Dimensions ext.: 80 x 80 x 205 mm 3’’ ¼ x 3’’ ¼ x 8’’ Dimensions int. reactor: Ø 60x130 mm 2’’ ¼ x 5’’ ¼ Ø outlets: 6 mm (¼’’) Flexible pipe equipped with a non-return valve Video on www.sciencethic.com The interior space has been designed to allow a 100 ml tall form beaker to fit in.

The beaker, ethanol lamp and safety cables are not supplied with this device. Transparent plates designed to fit with 1 low form beakers of 250 mL One resistance stand equipped with a coiled resistor Ø 4 mm (0,16’’) banana plug which accepts safety cables Beaker, ethanol lamp and safety cabler not supplied Video on www.sciencethic.com Scan the QR code with your smartphone.
