All ILS syringes are manufactured at our manufacturing facility in Germany from high quality DURAN® Borosilicate 33 Type I expansion glass. The 33 expansion glass is the highest chemical resistance and lowest expansion glass that is used for syringe manufacturing and produces the best precision and calibration. All PTFE and metal parts are designed and manufactured in-house using state of the art computer-controlled milling and lathing machines and specialized glass shrinking equipment.
ILS uses a unique process to apply the label markings to the glass barrel. The markings are screen-printed with silver ink and then heated. A chemical exchange occurs between the boron in the glass and the silver to etch the unique brown-colored markings that will not wash off, rub off, or fade over time.
The glass microsyringe is one of the most commonly used items in science laboratories of all types. There are many different syringe models available to address the hundreds of different applications this precision tool is used for. All syringes begin with a high-quality glass barrel, then the other parts are constructed as needed for each use. The syringe catalog helps to direct you to the specific syringe you need either by type or by application.
Because ILS produces all parts of all syringes in our own manufacturing facility we are able to manufacture virtually any syringe configuration that you require. You can build your own syringe with the needle, plunger, barrel, and end fittings that will best suit your needs. If you require a customer syringe you may complete the Syringe Questionnaire, or Contact Us for help.
Needle Tip "A"
Needle Tip "B"
Needle Tip "C"
Needle Tip "D"
|Gauge||O.D. mm||I.D. mm|
|Fixed Needles. The needle is permanently attached to the glass barrel with glue. Not autoclavable. This design has the least carryover.|
|Removable Needles. The needle can be removed by unthreading. This allows the needle to be replaced if desired due to damage.|
|Screw thread 1/4"x28 UNF. Also called "C" and CX" type.|
|Screw thread 1/4"x28 UNF.|
|Screw thread M10.|
|Screw thread M8 x 0.75. Also called "AD" type.|
|Screw thread M8 x 0.75 with side connection internal threads M6 x 1. . Also called "DAD" type.|
|Screw thread M10.|
|Luer connection with side connection internal threads M6 x 1. Also called "D" type.|
|Luer connection PTFE. Also called "TLL".|
|Luer connection, glass taper.|
|Luer connection, PTFE taper.|
|Tubing connector, available either with Mx or 4x28 threads.|
|Stainless steel plunger for general purpose operation with liquids. Plunger is matched to the barrel and cannot be interchanged.|
| Type N
|Super flexible plunger is very resistant to bending and also resistant to salt buffers. Plunger is matched to the barrel and cannot be interchanged.|
|Stainless steel plunger with seal attached to the end, suitable for liquids and gases. Also called "gas-tight". The standard seal material is PTFE. Other seal materials may be specified (see below). On most models the seal can be replaced and the plunger can be replaced if necessary.|
|PTFE virginal||Standard Teflon seal for high chemical resistance. It is low wetting and has good gliding characteristics. It will expand at higher temperatures.|
|PTFE modified||Teflon with lubrication for lower friction and longer lifetime for automatic liquid handling.|
|PE HD||High density polyethylene for better durability with high salt concentration buffers.|
|PTFE special black||New material from ILS has even less friction, less high-temperature expansion, and less electrostatic charge than virgin PTFE and maintains high chemical resistance. It has less cold flow and will provide the highest robustness and longevity. Add "bl" to the part number to order a syringe with the PTFE black seal.|
|Similar to the standard knob, but has internal 6-32 UNC threads in the top to allow attachment via a screw. A set screw on the side allows it to be locked.|
|Has internal 6-32 UNC threads in the top to allow attachment via a screw. A set screw on the side allows it to be locked.|
|Has internal 6-32 UNC threads in the top to allow attachment via a screw.|
|Plunger top with mounting hole. Also called "XL" type.|
|Plunger top with mounting hole and knurled screw.|
|Tapered plunger top with mounting hole and knurled screw.|
|Plunger top, ball style. Also called "XE" style.|
|Plunger top, indented style. Also called "XP" style.|
