害の原因になることがある。Problems to be solved by the present invention However, such means can cause the tip of the pipette to become clogged and create a rough surface, which can cause damage to, for example, plant cells.
問題点を解決するための手段
この発明は１品質の良いピペットを製造し得る製造装置
を提供するものであって、つぎのような技術的手段を講
じた。Means for Solving the Problems The present invention provides a manufacturing apparatus capable of manufacturing pipettes of good quality, and takes the following technical measures.
即ち、中空形状の筒体１と、該筒体１の外周部に設けた
外部加熱手段と、該筒体１に内装した内部加熱手段と、
筒体ｌの軸芯方向に引張力を付与する引張力付与手段と
を備えてなるピペットＩ２造装置の構成とする。That is, a hollow cylinder 1, an external heating means provided on the outer circumference of the cylinder 1, and an internal heating means installed inside the cylinder 1,
The apparatus for making a pipette I2 includes a tensile force applying means for applying a tensile force in the axial direction of the cylinder l.
作用
まず、外部加熱手段でもって筒体１の外周部を加熱する
。つぎに、′筒体１を引張力付与手段でもって筒体１を
軸芯方向に引張る。そして、内部加熱手段で筒体１を加
熱すると、この筒体１を切断することができる。Operation First, the outer peripheral portion of the cylinder 1 is heated using an external heating means. Next, the cylindrical body 1 is pulled in the axial direction using a tensile force applying means. Then, by heating the cylindrical body 1 with the internal heating means, the cylindrical body 1 can be cut.
効果
切断後におけるピペットの先端部を先細でがっ滑面に形
成することができる。Effect: The tip of the pipette after cutting can be formed into a tapered and rounded smooth surface.
実施例 以下、この発明の一実施例を図面に基づいて説明する。Example Hereinafter, one embodiment of the present invention will be described based on the drawings.
まず、その構成について説明すると、筒体１はガラスで
中空状に形成するとともに両端面を開放している。そし
て、該筒体１の中間部の外周面にコイル状の外部加熱具
（例えば、電熱線）２を設けており、また、筒体１の内
部には、端部が筒体１の端面の外方に位置し、かつねじ
７で着脱自在に取付けている内部加熱具（実施例では極
細の白金線である）３を設けている。なお、該外部及び
内部の両加熱具２・３を電源（図示せず）に接続し通電
可能に構成している。First, the structure will be described. The cylindrical body 1 is made of glass and has a hollow shape, and both end faces are open. A coil-shaped external heating device (for example, a heating wire) 2 is provided on the outer circumferential surface of the intermediate portion of the cylinder 1, and inside the cylinder 1, an end portion is formed on the end surface of the cylinder 1. An internal heating device 3 (in the embodiment, it is an extremely thin platinum wire) is provided, which is located on the outside and is detachably attached with screws 7. Note that both the external and internal heating tools 2 and 3 are connected to a power source (not shown) so that they can be energized.
４は前記筒体１の両端部に取付けたホルダーであって、
一方を引張力付与手段（実施例では、ソレノイド）５で
もって矢印方向に移動可能に設けている。なお、移動可
能に設けているホルダー４は固定の軸６に挿通しこの軸
６に沿って軸芯方向に移動する構成としている。８は筒
体取付ねじである。4 is a holder attached to both ends of the cylinder 1,
One side is provided so as to be movable in the direction of the arrow by means of a tensile force applying means (a solenoid in the embodiment) 5. The movable holder 4 is inserted into a fixed shaft 6 and moved in the axial direction along this shaft 6. 8 is a cylinder mounting screw.
つぎに、その作用について説明すると、まず、筒体１の
中間部を外部加熱具２に挿通してから。Next, the operation will be explained. First, the middle part of the cylindrical body 1 is inserted into the external heating tool 2.
上下両端部を夫々のホルダー４に取付ける。そして、内
部加熱具３を筒体１に挿通して夫々の端部をねじ７で固
定する。つぎに、外部加熱具２に通電すると、この外部
加熱具２は発熱して筒体１を加熱する。そして、所定時
間経過後にソレノイド５を励磁すると、下側のホルダー
４は軸６に沿って矢印イ方向に引張られるので、これに
関連して筒体１が伸びて中間部が細くなる（第２図参照
）。Attach the upper and lower ends to the respective holders 4. Then, the internal heating device 3 is inserted into the cylindrical body 1 and each end portion is fixed with a screw 7. Next, when the external heating tool 2 is energized, the external heating tool 2 generates heat and heats the cylindrical body 1. Then, when the solenoid 5 is energized after a predetermined period of time has elapsed, the lower holder 4 is pulled in the direction of arrow A along the shaft 6, and the cylindrical body 1 is elongated in relation to this, and the middle part becomes thinner (second (see figure).
つぎに、内部加熱具３に通電すると、この細くなった筒
体１が切断される。そして、ねじ７を緩めて内部加熱具
３を筒体１から引抜くと所望のマイクロピペットを成形
することができる。（第３図参照）したがって、このマ
イクロピペットの先端部に極細の吸入口および滑らかな
面を形成できる。Next, when the internal heating tool 3 is energized, this narrowed cylinder 1 is cut. Then, by loosening the screw 7 and pulling out the internal heating tool 3 from the cylindrical body 1, a desired micropipette can be formed. (See FIG. 3) Therefore, an extremely thin suction port and a smooth surface can be formed at the tip of this micropipette.
