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. The syringes in this series have a built-in Chaney adapter installed by the factory for reproducible injections. Factory installation ensures the adapter is applied correctly and eliminates inadvertent damage caused by incorrect do-it-yourself assembly. This is especially critical for 7000 series syringes that have extremely small plunger wires.

Syringes in this category are either 700 and 7000 series Microliter™ or 1700 and 1000 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.

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. Luer Tip (LT)- The needles are removable and fit over a ground glass hub which is tapered in the shape of a male luer. The LT termination will accept most hypodermic needles but was designed specifically for use with Hamilton Kel-F needles. This termination increases the dead volume in the syringe, which may not be appropriate for some applications. Autoclavable when disassembled. Luer Tip Cemented Needle (LTN) - For mid 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. PTFE Luer Lock (TLL) – This is a male luer with a nickel plated brass hub. This termination accepts metal hub and Kel-F hub needles and locks them in place.

Needle Point Style 2 - Sharp, beveled, curved, non-coring needle point recommended for septum penetration. Available gauges: 26s, 22s, 22. Needle Point Style 3 - Blunt needle point for use with HPLC injection valves and for sample pipetting. Available gauges: 22s, 23s, 24, 25s.
