These syringes are the Gastight® version of the original 700 series syringes and are ideal for dispensing volumes from 1 µl up to 500 µl.
- Fluid path includes stainless steel, borosilicate glass and PTFE
- Gas sterilisable
Gastight® syringes are ideal for dispensing both liquids and gases and have a precision machined PTFE plunger tip which creates a leak free seal. With the tight fit, the tip essentially wipes the interior of the syringe barrel free of sample. This feature is particularly useful with heterogeneous samples as it reduces the chance that a deposit will occur and cause the plunger to freeze.
Cemented needle (N): Cemented needles for low volume syringes are cemented into the glass syringe barrel at a point corresponding to the zero graduation mark. With this termination, dead volume is limited to the internal volume of the needle. Not autoclavable. Needle gauge is determined by the syringe volume and are not user-selectable.
Removable needle (RN): The design allows the needles to seat precisely at the zero graduation mark of the syringe. Users can select the needle gauge, length, and point style to optimize the syringe for custom applications. This termination also allows for a removable needle without increasing the dead volume of the syringe and is ideal when there is a risk of the needle clogging. Autoclavable when disassembled. Repeated autoclaving will shorten syringe life.
Luer tip (LT): Luer tip syringes feature needles that are removable and fit over a ground glass hub which is tapered in the shape of a male Luer. This termination will accept most hypodermic needles but was designed specifically for use with Hamilton Kel-F needles. This termination also increases the dead volume in the syringe, which may not be appropriate for some applications. Autoclavable when disassembled.
Luer tip cemented needle (LTN): Luer tip cemented needle syringes are mid-volume syringes in which the needles are cemented into the glass syringe barrel at a point corresponding to the zero graduation mark. With this termination, dead volume is limited to the internal volume of the needle. Not autoclavable. Needle gauge is determined by the syringe volume and are not user-selectable.
PTFE Luer lock (TLL): PTFE Luer lock syringes have a PTFE, male Luer taper with nickelplated brass locking hub for use with Kel-F needles, metal hub needles, and universal connectors. This termination is also used with Hamilton diluters/dispensers, OEM applications, and manual operations. The version with slots is used during the attachment to some instruments but does not effect the connection to needles. Autoclavable when disassembled, except on 25 ml and greater syringes. Repeated autoclaving will shorten syringe life.
Needle point style 2: Sharp, beveled, curved, non-coring needle point recommended for septum penetration.
Needle point style 3: Blunt needle point for use with HPLC injection valves and for sample pipetting.
Needle point style 5: Conical needle with side port for penetration of septa, thin-gauged vinyls, and plastics without coring.
