Abstract
A diffusion dish includes a dish body with inner and outer cavities, and a dish cover, the dish body and the dish cover are combined with thread style, the dish cover is provided with a liquid adding hole corresponding to the outer cavity and is provided with a hole plug, a movable dish is arranged in the inner cavity. Used in the soil available n determination or medical chemical examination and other experimental analysis, the diffusion dish can efficiently reduce experimental rework rate, avoid the effect of operator proficiency to the experimental result, and improve work efficiency and precision degree of experimental analysis.
Description
One, technical field
The utility model relates to a kind of experimental analysis instrument and equipment, is specifically related to a kind of diffusion boat.
Two, background technology
The soil alkali-hydrolyzable nitrogen is measured and will be carried out in diffusion boat, the general diffusion boat that uses is glass apparatus, form by ware body and ware lid two parts, the inside and outside chamber of ware body adds boric acid and soil sample respectively during use, smear Arabic gluing grade for sealant in upper edge, the external limit of ware, ware is covered, then pass ware and cover at exocoel adding alkali solution liquid, pass again and build the ware lid, spread absorption reaction.In operating process, situation poorly sealed and that be difficult for discovering takes place easily, and mobile ware lid liquid feeding inconvenience, the reinforced diffusion boat of must not changing on time in inside and outside chamber restarts, rework rate is higher, and technical level of operators is had relatively high expectations, and influences work efficiency.
Three, summary of the invention
The object of the present invention is to provide a kind of novel diffusion boat, can security seal, and interior exocoel split, reinforced convenient.
A kind of novel diffusion boat that the utility model provides comprises the ware body that has inner chamber and exocoel, the ware lid, and described ware body cooperates for screw-type with the ware lid, and ware covers and has the liquid filling hole corresponding with exocoel, and stopple is set, and movable ware is set in described inner chamber.
The utility model ware lid cooperates with ware body screw-type, can avoid poorly sealed error, covers perforate and stopple is set at ware, can carry out liquid feeding by it, because inner chamber and exocoel split-type design are independent of each other when reinforced, can all not do over again in addition because of reinforced error in the chamber.This diffusion boat is used for experimental analyses such as soil alkali-hydrolyzable nitrogen mensuration or medical science chemical examination, can effectively reduce the experiment rework rate, avoids the influence of operator's skill level to experimental result, improves experimental analysis work efficiency and precision.
Four, description of drawings
Fig. 1 is this diffusion boat diagrammatic cross-section.
Five, embodiment
Embodiment 1.
As Fig. 1, a kind of diffusion boat, comprise the ware body 1 that has inner chamber 5 and exocoel 4, ware lid 2, described ware body 1 and ware lid 2 cooperates by screw thread 3, and ware covers and has the liquid filling hole 8 corresponding with exocoel 4 on 2, and stopple 7 is set, movable ware 6 is set, and described ware body 1, ware lid 2 and movable ware 6 are column type in described inner chamber 5.Present embodiment is except that stopple 7 usefulness rubber materials, and all the other materials are resin.
The diffusion boat of present embodiment adds soil sample in exocoel 4 when being used for soil alkali-hydrolyzable nitrogen mensuration, add boric acid in the inner chamber 5, cover and screw ware lid 2, add behind the alkali lye stopple 7 beyond the Great Wall by liquid filling hole 8, after alkaline hydrolysis diffusion and absorption were finished, the ware of opening an account lid 2 carried out titration.
Claims (2)
1. diffusion boat, comprise the ware body (1) that has inner chamber (5) and exocoel (4), ware lid (2), it is characterized in that described ware body (1) cooperates for screw thread (3) formula with ware lid (2), have the liquid filling hole (8) corresponding on the ware lid (2) with exocoel (4), and stopple (7) is set, movable ware (6) is set in described inner chamber (5).
2. diffusion boat as claimed in claim 1 is characterized in that described ware body (1), ware lid (2) and movable ware (6) are column type.
