Abstract
A sheath liquid supplying apparatus includes a syringe including a piston and a cylinder slidably accommodating the piston and a stepping motor for causing the piston to slide in the cylinder, wherein the cylinder has an injection/suction hole of a sheath liquid positioned at a distal end thereof and a gas introducing hole positioned at a side wall thereof for introducing gas into the cylinder.
Claims27
A sheath liquid supplying apparatus comprising:
- a syringe including a piston and a cylinder slidably accommodating the piston,
- a driving motor for causing the piston to slide in the cylinder,
- wherein the cylinder has a liquid hole for injecting a sheath liquid therethrough out of the cylinder and a gas hole for introducing a gas into the cylinder therehrough.

A flow cytometer comprising:
- a sheath flow cell;
- a syringe including a cylinder and a piston, said piston and cylinder changeable their relative position to accommodate the sheath liquid therein as well as to supply the sheath liquid to the sheath flow cell therefrom, said syringe provided with a liquid hole for supplying the sheath liquid therethrough to the sheath flow cell and a gas hole for supplying a gas therethrough into the cylinder, said gas hole located relatively above the liquid hole in the syringe;
- and
- a driving motor for changing the relative position of the piston and the cylinder with the gas being present between the sheath liquid and the piston, whereby the sheath liquid in the syringe is supplied through the liquid hole to the sheath flow cell.
1 more element
An apparatus or analyzing particles using a sheath flow method comprising:
- a measuring section detecting signals from particles;
- a syringe including a piston and a cylinder slidably accommodating the piston, said piston and cylinder being changeable in their relative position to accommodate the sheath liquid therein and supply the sheath liquid to the measuring section, said cylinder having a liquid hole for injecting a sheath liquid therethrough and a gas hole for introducing a gas therethrough into the cylinder;
- a driving motor for relatively changing positions of the piston and the cylinder with the gas being present in the cylinder, whereby the sheath liquid in the syringe is supplied through the liquid hole to the measuring section for forming the sheath flow.
