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 On Column gas chromatography (GC) injectors. Syringes in this category are either 700 or 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.

Special Cemented Needle (SN)- 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. Special length.

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. Removable Needle Fused Silica (RNFS)- 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. These RN have a fused silica needle coated with polyimide. Knurled Hub (KH)- The knurled hub is used exclusively on 7000 series syringes. The hub handles up to 6000 psig maximum injection pressure. The needle is removable but with a limited number of gauges available because the plunger is fitted inside the needle. Autoclavable when disassembled. Repeated autoclaving will shorten syringe life.

Needle Point Style 2 - Sharp, beveled, curved, non-coring needle point recommended for septum penetration. Available gauges: 32. Needle Point Style 3 - Blunt needle point for use with HPLC injection valves and for sample pipetting. Available gauges: 0.17 mm, 0.23 mm, and 32.
