Abstract

The utility model relates to a cell micrographic operation glass slide. The center of the glass slide is provided with an oblong and concave operating room. The utility model better solves the visual sensation errors caused by the existing and inequable bottom thickness of the round and concave glass slide and the operation inconvenience caused by the large inserting needle angle. The utility model has the advantages that operational area is increased and work efficiency is enhanced.

Description

Flat square groove type cell micrurgy slide glass

The utility model is to carry out the cell micrurgy with flat square groove type slide glass about a kind of microscopically that is applicable to.

The structure of cell micrurgy slide glass product is the very shallow garden depression slide in a kind of bottom both at home and abroad, because the uneven thickness of bottom glass, light is by refractive angle difference behind the slide, under observation error will appear, when the pair cell micrurgy, entry needle must be parallel vertical with cell surface with the slide glass bottom as far as possible, cell just is difficult for rolling, the tip of pin is the easier cytolemma that punctures just, and the garden depression slide, generally about 15 ℃, during operation, rotating and the necrocytosis problem of higher can appear the angle on its bottom and limit in cell; Spill slide bottom, garden is a curved surface, and cell attachment is grown in the slide bottom, can not be used for injection cell; Garden spill slide groove shallow (less than 0.7mm), diameter little (having only 10-15mm), actually operating area 0.5mm ², regulating what use because of the pH value of nutrient solution again is CO ₂So, can not be exposed in the air, but nutrient solution is that after entry needle entered drop, its surface tension reduced with the capping of whiteruss surface tension that nutrient solution will come out, and the pH value of nutrient solution is changed, and influences operating effect.

The purpose of this utility model is to design a kind of flat square groove type cell micrurgy slide glass, with handled easily, reduces error, improves operation efficiency and quality.

The utility model is achieved in that a kind of cell micrurgy slide glass, and there is a rectangle spill chamber in slide glass central authorities, the suitable for reading long 30mm of spill chamber, and wide 10mm, the long 20mm of end mouth, wide 10mm, the dark 1.5mm in chamber is two dimensional structure.

Advantage of the present utility model:

1. flat square groove operation slide glass, owing to be flat, bottom glass thickness uniformity has been eliminated the error that the curved end produces, flat being convenient to again injected the cell of bottom adherent growth.

2. increased operations area, the area of flat shape groove operation slide glass is 20mm * 10mm=2cm ², the operations area of garden spill slide is 0.5mm ²

3. improved working efficiency, the entry needle inclination angle is littler 2 times than garden flute profile slide, and entry needle just need not processed and can operate.

The present invention has following accompanying drawing:

The flat square groove shape of Fig. 1 micrurgy slide glass floor map;

The flat square groove shape of Fig. 2 micrurgy slide glass sectional view;

The flat square groove shape of Fig. 3 slide glass operation chart.

Description of drawings:

Fig. 1 shows flat square groove operation slide glass orthographic plan, 1. slide glass central recessed chamber, and slide glass is to select the good soft rectangle sheet glass of optics degree among the figure.

Fig. 2 shows flat square groove operation slide glass sectional view, 1. rectangle alcove, 2. slide glass.

Fig. 3 shows the operation chart of flat square groove type micrurgy slide glass, 1. square groove operation, 2. garden shape groove operation.Its injection inclination angle, spill chamber than depression slide inclination angle, a garden young waiter in a wineshop or an inn doubly.

Most preferred embodiment of the present invention:

The long 75mm of slide glass, wide 25mm has the spill chamber in slide glass central authorities, its long 30mm suitable for reading, wide 10mm, the long 20mm in the end, wide 10mm, the dark 1.5mm in chamber.

Claims

1. cell micrurgy slide glass, it is characterized in that: there is a rectangle spill chamber in slide glass central authorities.

2. slide glass according to claim 1 is characterized in that spill chamber long 30mm suitable for reading, wide 10mm.

3. slide glass according to claim 1 is characterized in that the long 20mm in bottom of spill chamber, wide 10mm, and the end, be two dimensional structure.
