The tube body is attached to at least one flange via an attachment device which avoids any torque on the seal gasket. The flange and tube body are in direct contact with each other and the seal gasket is between the transparent tube and the flange having pressure applied in the same fixed volume and pressure each time the device is assembled. ## Claims ### Claim 1 An assembly (100) comprising; an assembly longitudinal axis (200), a tube body (4000), a first flange (2000), a transparent tube (5100), a first seal gasket (6200), a first attachment mechanism (1000), a first placement holder (6000); wherein the tube body has a tube body longitudinal axis (4030), a tube body first end (4400) which has a tube body first end contact surface (4450), a tube body second end (4500), a tube body inside diameter (4200), a window (4100); the transparent tube has a transparent tube first end (5100), a transparent tube first end contact surface (5200), a transparent tube second end (5150), a transparent tube second end contact surface (5250), a transparent tube inside diameter (5300), a transparent tube outside diameter (5250) which is less than the tube body inside diameter, a transparent tube longitudinal axis (5300), the first flange having a first flange longitudinal axis (2030), a first flange seal end (2100), a first flange connection end (2200), a first flange seal surface (2300), a first flange set surface (2500); and wherein the transparent tube is located inside the tube body; the first placement holder is separate from the first flange, is located between the tube body and the transparent tube, and is in contact with the transparent tube; the assembly longitudinal axis, the tube body longitudinal axis, the transparent tube longitudinal axis, and the first flange longitudinal axis are on substantially the same line; the tube body first end contact surface touching the first flange set surface, fixing a volume of the first seal gasket to prevent over or under torquing of the gasket; and a portion of the first seal gasket is under pressure and in contact with the first flange seal surface and the transparent tube first end contact surface. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the assembly is a bubble trap. ### Claim 3 (depends on 1) The assembly of claim 1, further comprising a second flange (3000), a second seal gasket (6300), a second attachment mechanism (1500);
