Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in fig. 1-3, the utility model provides a pair of clean bench of aquatic bacteria total number survey, including base 1 and culture dish 2, base 1 upside is equipped with four recesses 11, culture dish 2 includes base plate 21, base plate 21 downside integral type is equipped with four lugs 22 base plate 21 upside is equipped with four grooves 23 of stepping down, and four grooves 23 of stepping down set up with four lugs 22 one-to-one, and every groove 23 of stepping down inboard bottom all is equipped with culture tank 24, and culture tank 24 downwardly extending stretches into in the lug 22. The cover plate is movably matched and connected in the abdicating groove 23, the culture groove 24 can be covered by the cover plate, and heat preservation is conveniently carried out on the culture groove.
