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.

Reading graduations is always a challenge

Hamilton digital syringes eliminate parallax errors by providing a digital readout on an integrated LCD screen. An adjustable plunger-stop guarantees reproducible plunger placement. Easily achieve precision up to 0.5% while dispensing volumes from 500 µL down to 50 nL. Easy-To-Read
Now you don't have to read between the lines to determine how much sample is in your syringe. With the digital syringe, you read the syringe volume directly from the LCD. The display eliminates volume reading errors as well as ensures everyone reads the syringe volume the same.

Ideal for Instrument Calibration
Every digital syringe is a calibrated device traceable to N.I.S.T. methods. Use it to calibrate analytical instruments (AA/ICP, GC, HPLC, etc.), prepare standards and spike samples. The certified device makes it easier to comply with EPA, CLIA, ISO and FDA (GLP, GMP) requirements.

Better Accuracy and Precision
700 series Microliter™ and 1700 series Gastight® digital syringes are certified to ± 0.5% accuracy or better. 7000 series Microliter™ syringes are certified to ± 1.0% accuracy or better. Improve precision with the built-in adjustable plunger stop (0-100% of syringe volume) that is engaged with a touch of the button.

Digital Syringe Terminations: 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.
Special Cemented Needle (SN) - For low volume syringes the special needle terminations are the same as the Cemented Needle terminations except they allow for a variety of user-defined gauges, lengths, and point styles to be attached.
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) - 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.
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.
Needle Point Styles: Point Style 2 - Sharp, beveled, curved, non-coring needle point recommended for septum penetration. Available gauges: 34-22.
Point Style 3 - Blunt needle point for use with HPLC injection valves and for sample pipetting. Available gauges: 34-22.
