You can choose between two needle types – fixed or removable.
Removable needle: The needle can be removed and replaced by a new one in case the needle is bent or damaged. These syringes are autoclavable.
Fixed needle: The needle is attached to the glass barrel and cannot be removed. These syringes are not autoclavable, but have the least carryover.
There are also different syringe tip styles you can choose from depending on the requirements of your application.
The standard dispensing syringes come with various types of plungers that differ in regard to the application.
Plunger rod can have an additional seal mounted at the top of the end of the syringe barrel. The seal at the headspace provides the leak-proof sealing between plunger and syringe barrel. The sealing affords the user to gain better control over dosing and smoother injection. It is also necessary for dispensing of gas.
The Luer system is a standardized connection system for quick coupling and decoupling of cannulas or tubes. The standardization ensures compatibility of leak-free connections for small-scale fluid fittings between different manufacturers of the syringes and analytical instruments.
The seal is achieved by a cone-shaped construction of the connecting parts (Luer cone). One side of the connection's inner cone is referred to as female and the outer cone on the opposite side as male. The products manufactured in the Luer standard are commonly referred to as Luer Lock Syringes.
The Luer system enables quick and simple assembly of the syringe. It is either a pure plug connection or, if the male cone is provided with an internal thread, a screw connection that can be closed and opened without tools. The connection is fixed by turning it slightly so it cannot become loose under slight mechanical stress, thus reducing the risk of error.
The seal provides leak-proof sealing between the plunger and the syringe barrel. Depending on the medium you are using in the syringe, ILS offers different types of seal materials that you can choose from with different kinds of chemical resistance and abrasiveness.
Series N – standard glass syringes for liquids
It features the most popular plunger crafted for a liquid dispensing and made from stainless steel.
It is exceptionally tightly fitted into the glass barrel what is the desired solution for dispensing liquids. The stainless steel plunger rod is well-mounted in the barrel, to allow for exact dosing. It is fixed and thus cannot be replaced.
Series H – gas tight micro syringes
H series features seals made from PTFE or PE.
The PTFE is a standard seal material. It is most commonly known as Teflon® or polytetrafluorethylene. PTFE plunger topping provides a gas tight sealing for the headspace, which makes it applicable for dispensing both liquids and gas.
PE-HD Seals provide better durability than PTFE when working with salty solutions. High-density polyethylene is well-known for its low coefficient of friction which provides smooth operations. HDPE materials durability against impact and abrasion.
Series P – micro syringes with adjustable seal
For gas chromatography and HPLC valves, ILS delivers syringes with adjustable PTFE seals. They are equipped with screws that enable regulation of seal-pressure. Adjustable PTFE seals give the user control over increasing or decreasing of the seal pressure according to dosage requirements.
Series G – micro syringes with an additional seal at the topping
For applications and equipment that requires dosage under counter pressures, ILS provides Static PTFE-Seal at the top of the glass barrel for an additional seal at the topping.
Series T - Zero Dead Volume glass syringes
Whenever a superior accuracy in a small dosage of liquid is required, a syringe with zero dead volume design is the best solution. In the T series plunger also runs inside the needle, allowing for dosage as low as 1 microliter.
Series SN/SH – glass syringes with extended handle
Specialized construction of the plunger prevents the content from being heated by the hand of the user. The plunger rod is designed in a way that protects it from bending. Both the SH and SN series find application for gas chromatography and HPLC valves
ILS offers over 1000 types and variations of glass syringes made from the highest quality of the borosilicate glass. The complete manufacturing process is done in-house. In addition to great engineering expertise and customer service, we offer unique possibilities of customized solutions to match the individual needs of our customers.
ILS product range focuses on two types of glass syringes – designed for use in syringe pumps and the analytical one for use in various lab instruments and liquid handling applications.
Analytical syringes are used in laboratory instruments for analytical applications such as gas and liquid chromatography or mass spectrometry. They are usually equipped with a needle and the volume size ranges from 100µL to 5ml.
ILS offers glass syringes for syringe pumps that are part of liquid handling instruments. They are an industry standard product compatible with all common syringe pumps from different manufacturers. The volume size ranges from 0.5 ml up to 25 ml.
ILS syringes for dispensing or diluting liquid is also fully compatible with the instruments from Hamilton, Trajan/SGE, Koehn/IMI, as well as other manufacturers - Tecan, Thermo Fisher Scientific, Agilent, ITO, Perkin Elmer, Waters, Setonic, MK Fluidics, Flex Fluidics, Vici and Zinsser Analytic.
