Description
54) УСТРОЙСТВО ДЛЯ ОПРЕДЕЛЕНИЯ ГАЗООБМЕНА ВОДОРОСЛЕЙ54) DEVICE TO DETERMINE THE GAS EXCHANGE OF ALGAE
Изобретение относитс к измерительным приборам и может быть использовано дл измерени газообмена водных растений.The invention relates to measuring instruments and can be used to measure the gas exchange of aquatic plants.
Известно устройство дл определени газообмена водорослей/ .содержащее камеру, сообщающуюс с атмосферой через капилл р, оснащенный шкалой 1 .A device for determining the gas exchange of algae / containing chamber, which communicates with the atmosphere through a capillary equipped with a scale of 1, is known.
Однако в данном устройстве при длительных измерени х посто нно измен ютс параметры среды, что вли ет на состо ние исследуемого объекта.However, in this device, during long-term measurements, the parameters of the medium constantly change, which affects the state of the object under study.
Цель изобретени - повышение длительности непрерывных измерений.The purpose of the invention is to increase the duration of continuous measurements.
Дл достижени указанной цели устройство снабжено сифоном и дозатором с насадкой в виде цилиндрического , стакана с отверстием в его нижней части, капилл р со шкалой при-креплен к камере под углом к горизонтали , пpичeVl сифон соединен с капилл ром в месте нулевой отметки его шкалы, а колено сифона расположено на уровне предельной отметки шкалы капилл ра, при этом под сливным отверстием сифона установлена калиброванна пробирка.To achieve this goal, the device is equipped with a siphon and a dispenser with a nozzle in the form of a cylindrical cup with a hole in its lower part, a capillary with a scale attached to the camera at an angle to the horizontal, and the Vip siphon is connected to the capillary at the zero point of its scale, and the knee of the siphon is located at the level of the limit of the capillary scale, while a calibrated test tube is installed under the drain hole of the siphon.
На чертеже показано предлагаемое устройство.The drawing shows the proposed device.
Устройство дл определени газообмена водорослей содержит замкнутую .камеру 1 дл исследуемого объекта, наклонный капилл р 2, расположенный под углом 6-8 к горизонтали и оснащенный шкалой, сифон 3, соединенный с капилл ром 2 в месте нулевой отметки 4 шкалы, причем колено сифона 3 расположено на одном уровне с пре10 дельной отметкой 5 шкалы, градуированную пробирку,б, расположенную под сливным отверстием сифона 3, дозатоо 7, состо щий из резервной емкости 8, трубки 9, насадки 10 с отверстием 11 The device for determining the gas exchange of algae contains a closed chamber 1 for the object under study, an inclined capillary tube 2, located at an angle of 6–8 to the horizontal and equipped with a scale, a siphon 3 connected to capillary 2 at the zero point of the scale 4, and the knee of the siphon 3 located on the same level with the limit mark 5 of the scale, graduated test tube, b, located under the drain hole of the siphon 3, dozatoo 7, consisting of a reserve tank 8, tube 9, nozzle 10 with a hole 11
15 на боковой поверхности и отверстием .12 в дне.15 on the side surface and the hole .12 in the bottom.
Устройство работает следующим образом .The device works as follows.
Камеру 1 после помещени в нее Camera 1 after being placed in it
20 водорослей герметично соедин ют с дозатором 7 и через кран дозатора 7 заполн ют питательной средой, при этом сливное отверстие сифона 3 перекрывают . После заполнени камеры20 algae are sealed to the dispenser 7 and filled with a nutrient medium through the dispenser valve 7, while the drain hole of the siphon 3 is blocked. After filling the chamber
