Microliter™ and Gastight® Agilent 7673, 7683, 7693 and 6850 ALS GC Syringes, Hamilton

Hamilton Company offers the most comprehensive selection of standard and custom syringes in the industry

Each is manufactured to achieve the highest level of accuracy and precision possible. These syringes are designed to work with Agilent 7673, 7683, 7693 and 6850 Automatic Liquid Sampler (ALS) gas chromatography (GC) autosamplers. Syringes in this category are either 700 and 7000 series Microliter™ or 1700 series Gastight® syringes. Microliter™ syringes have a stainless steel plunger that is hand fitted to the glass barrel and are designed for liquid sampling. Gastight® syringes have a PTFE plunger tip that creates tight connection between the syringe barrel and plunger allowing for liquid or gas sampling. The flowpath for Microliter™ syringes includes SST and Borosilicate glass; Gastight® syringes include SST, Borosilicate glass, and PTFE.

Cemented Needle (N)- For low volume syringes, 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.

Removable Needle (RN)- The needles are removable and are a Hamilton-specific design. 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. Additionally, this termination 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.

Knurled Hub (KH)- Removable plunger/needle assembly, knurled hub is used exclusively on the 7000 series syringes.

Point Style 2 - Sharp, beveled, curved, non-coring needle point recommended for septum penetration. Available gauges: 23s or 26s. Point Style AS - Special conical style needle point used on autosampler syringes the non-coring needle point is recommended for septum penetration. Available gauges: 23s, 26s, 23s-26s.
