Welcome for the inquiry. 1351 Clear glass Desiccator with porcelain plate Product Description It is a non-vacuum desiccator, and therefore has no stopcock. The sturdy glass top fits easily on the thick lip of the desiccator, and features a knob handle for removing or replacing the lid. The lips of both the lid and the desiccator itself are ground glass, and should be greased with petroleum jelly before use. In addition to helping create an air-tight seal, the grease also helps cushion the lid when it is set down in place. To help prevent damage from being set down too forcefully, the lid can be carefully slid on, or off, of the desiccator once greased. Desiccators can be used, though not exclusively, for preserving moisture-sensitive items, protecting hygroscopic or water-reacting chemicals, as well as removing traces of water from samples that need drying. There are 8 sizes available : 120 mm desiccator, 150 mm desiccator, 180 mm desiccator, 210 mm desiccator, 240 mm desiccator, 300 mm desiccator, 350 mm desiccator, 400 mm desiccator.

Product model:CY-MSM20-8 (Non-consumable) metal melting suction casting furnace (Non-consumable) The metal melting suction casting furnace is a small arc melting furnace, which can either smelt metal ingots or suction ingots to achieve multiple uses in one furnace and meet the various needs of customers. The furnace is equipped with a visual vacuum pressure gauge to directly observe the vacuum degree in the chamber. The alloy ingot can be turned for multiple melting without damaging the protective atmosphere of the gas, and multiple samples (less than 7) can be prepared at the same time. It is an ideal equipment for preparing metal and alloy samples in universities and research institutes. It can be used for the preparation, purification and mixing of new alloy materials, such as high entropy alloy and high temperature alloy. (Non-consumable) The metal melting and suction casting furnace uses tungsten needles as electrodes. The melting point of tungsten is extremely high, and the arc temperature can reach 4000℃, which can melt almost all metals. During the working of the furnace, the electrodes and crucibles should be cooled with circulating water to ensure that the electrodes and crucibles will not be melted. Installation conditions This equipment is required to be used at an altitude below 1000m, temperature 25 ℃ ± 15 ℃, humidity 55% Rh ± 10% Rh. 1.

Workbench: (floor-standing) size 900mm × 600mm × 700mm, bearing more than 200kg 5. Ventilation device: need Main features 1. Equipped with a Ø120mm furnace door, convenient take put the samples. 2. With front and rear observation windows, it is convenient to observe the arc melting state. 3. The vacuum chamber, copper crucible, and arc starting electrode are all water- cooled. 4. The up and down movement adopts the steering wheel design, and the joystick can be rotated flexibly. 5. In order to ensure that the alloy ingot is turned for multiple melting without damaging the protective atmosphere of the gas, a manipulator turning mechanism is used in the melting furnace. 6. The crucible is small in size and large in number, which can facilitate the production of multiple samples and avoid mutual pollution between samples. 7. Simple operation, safe and convenient, compact design, minimal footprint. Technical parameters 1. Power supply: AC380V 50Hz (optional) 2. Overall power: <10KW (optional) 3.
