연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A disposable flow path having a manifold system that provides pressure resistance for the disposable device. The disposable device is comprised of a first rigid plastic sheet and a second rigid plastic sheet. Each sheet has two major surfaces and a thickness between them. At least one sheet surface has flow channels formed in it. The flow channels extend away from a first major surface and beyond the normal plane of a second major surface of the sheet. The sheets are liquid tightly sealed to each other at their adjoining first major surfaces. When each sheet contains a flow channel, the flow channels are aligned and in register with each other. One or more fittings can be secured in the flow channel(s) at an edge of the two liquid tightly sealed sheets. Alternatively, tubing is placed in the channels before the sheets are secured to one another.

1. A device for the treatment of liquids comprising a first sheet of rigid plastic material and a second sheet of rigid plastic material, each sheet has a first major surface and a second major surface and a thickness between the first and second major surfaces, each of the first and second sheets has one or more flow channels formed therein, the one or more flow channels are formed in each sheet in manner such that the area of the sheet where the one or more flow channels are formed extend away from the first major surface of the sheet and beyond the normal plane of the second major surface of the sheet, the first and second sheets are liquid tightly sealed to each other at their adjoining first major surfaces and one or more pieces of tubing for movement of the liquids are inserted in the one or more flow channels formed between the two sheets, wherein the one or more pieces of tubing substantially conform to the dimension of the flow channels and one or more fittings are secured to the one or more pieces of tubing in the one or more flow channels at an edge of the two liquid tightly sealed sheets. 2. The device of claim 1 further comprising one or more holes formed through at least one of the first or second sheets at a location over the one or more flow channels and a device selected from the group consisting of a sensor, filter and a fitting is liquid tightly attached to each of the one or more holes. 3. The device of claim 1 further comprising one or more holes through one of the first or second sheets at a location over the one or more flow channels, a device selected from the group consisting of a sensor, filter and a fitting being liquid tightly attached to the opening, the device is a sensor and the sensor is selected from the group consisting of temperature, pressure, conductivity, flow and pH sensors. 4. A device for the treatment of liquids comprising a first sheet of rigid plastic material and a second sheet of plastic material, each sheet has a first major surface and a second major surface and a thickness between the first and second major surfaces, each of the first and second sheets has one or more flow channels formed in it, the one or more flow channels are formed in each of the sheets in a manner such that the area of the sheet where the flow channels are formed extends away from the first major surface of the sheet and beyond the normal plane of the second major surface of the sheet, the first and second sheets are liquid tightly sealed to each other at their adjoining first major surfaces, one or more pieces of tubing inserted within the one or more flow channels, wherein the one or more pieces of tubing substantially conform to the dimension of the one or more flow channels, one or more fittings are secured to the one or more pieces of tubing at an edge of the two liquid tightly sealed sheets so as to function as a port for the system and one or more holes formed through at least one of the first or second sheets at a location over the one or more flow channels and a device selected from the group consisting of a sensor, filter and a fitting is liquid tightly attached to the one or more holes. 5. The device of claim 1 further comprising one or more holes formed through at least one of the first or second sheets at a location over the one or more flow channels and a filter being liquid tightly attached to the one or more holes. 6. The device of claim 1 further comprising one or more holes formed through at least one of the first or second sheets at a location over the one or more flow channels and a fitting being liquid tightly attached to the one or more holes. 7. The device of claim 3 wherein the device attached to the one or more holes is a filter. 8. The device of claim 3 wherein the device attached to the one or more holes is a fitting. 9. The device of claim 3 wherein the device attached to the one or more holes is a sensor is selected from the group consisting of temperature, pressure, conductivity, flow and pH sensors. 10. A system for the processing of a liquid comprising a device comprising a first sheet of rigid plastic material and a second sheet of plastic material wherein each sheet is formed of a polycarbonate material, each sheet has a first major surface and a second major surface and a thickness between the first and second major surfaces, each of the first and second sheets has one or more flow channels formed in it, the one or more flow channels are formed in each of the sheets in a manner such that the area of the sheet where the flow channels are formed extends away from the first major surface of the sheet and beyond the normal plane of the second major surface of the sheet, the first and second sheets are liquid tightly sealed to each other at their adjoining first major surfaces, one or more pieces of silicone tubing inserted within the one or more flow channels wherein the one or more pieces of silicone tubing substantially conform to the dimension of the flow channels and a first fitting secured at a first location in the silicone tubing in the one or more flow channels at a first edge of the two liquid tightly sealed sheets and a second fitting secured at a second location in the silicone tubing in the one or more flow channels at a second edge of the two liquid tightly sealed sheets, the first fitting being connected to a supply of liquid for processing and the second fitting being connected to a means to hold the liquid after passing through the tubing contained within the one or more flow channels. 11. The system of claim 10 further comprising one or more holes formed through at least one of the first or second sheets at a location over the one or more flow channels and a device selected from the group consisting of a sensor, filter and a fitting is liquid tightly attached to the one or more holes.
