Claim:
1. A nucleic acid extraction apparatus comprising: a container containing a solution comprising nucleic acid and undesired components, the container further comprising a membrane configured to capture nucleic acid; a rupturable capsule containing a wash buffer; a rupturing element for rupturing said capsule so as to release said wash buffer; a syringe device, said rupturable capsule being positioned within said syringe device, above a lower end of said syringe device and beneath a plunger of said syringe device, the lower end of said syringe device being shaped to fit into an open end of said container comprising a solution of nucleic acid and undesired components; the plunger of said syringe device being depressible so as to first force said solution comprising nucleic acid and undesired components through said membrane configured to capture nucleic acid such that the membrane retains nucleic acid while passing the undesired components of the solution therethrough; and wherein said plunger is further depressible so as to cause said rupturing element to rupture said rupturable capsule and release said wash buffer and to thereafter drive said wash buffer out of the lower end of said syringe device and through said membrane configured to capture nucleic acid, thereby leaving pure nucleic acid on said membrane.
