The present invention also provides the using method of the horizontal fixture of a kind of diffusion boat, may further comprise the steps:
(1), will be stamped the diffusion boat that frosted glass cover plate, inside contain testing sample and reagent and place on the base of the horizontal fixture of diffusion boat,
(2), unclamp fixed screw, adjust the elevating lever height, the vertical component of elevating lever is done in support bar and is moved up and down, when pressing plate contacts with the frosted glass cover plate, the fixed screw on the screwed support bar; The elastic force of spring is horizontally fixed on the base frosted glass cover plate and diffusion boat simultaneously,
(3), frosted glass cover plate and the diffusion boat that fixes moved in the insulating box together with the horizontal fixture of diffusion boat, for subsequent use.
The present invention is preferred, and the diffusion boat in the step (1) is the multilayer diffusion boat, and the multilayer diffusion boat is stacked placing on the base up and down.
The invention has the beneficial effects as follows:
1, the present invention is simple in structure, convenient fixing, the frosted glass cover plate can be fixed on the diffusion boat by the up-down adjustment elevating lever and by the elastic force of spring, to guarantee the diffusion boat sealing fully, in fixation procedure, diffusion boat is on the horizontal plane always, prevents the diffusion boat inclination and causes diffusion boat inner room and mistress's solution to mix, solve the interior mistress's solution of alkali-hydrolyzable nitrogen of measuring in the soil with the diffusion absorption method and be easy to mix, caused the technical problem of operation failure.The horizontal fixture of diffusion boat of the present invention is the accuracy rate original text fixedly, safety easy to use, and easily operation is time saving and energy saving, has improved operating efficiency.
2, convenient disassembly of the present invention unclamps fixed screw, and to the adjusted elevating lever, level is taken off diffusion boat and got final product.
3, pressing plate of the present invention bottom surface is covered with one deck cushion pad, and cushion pad effectively cushions pressing plate for the pressure of diffusion boat, and guarantee pressing plate to the diffusion boat surface stressed evenly.
