Get Precise, Repeatable Injections with a Gas-Tight Syringe System
Whether you are performing in-vivo injections for drug delivery calibrated extrusion studies, or any extremely sensitive, low-volume-based application, the quality and performance of your syringe system is paramount. Using a gas-tight syringe is critical for accuracy in various scientific and analytical applications for several reasons. Let’s consider a few instances.
Maintain a Controlled Environment
In studies involving samples sensitive to air or moisture, utilizing a gas-tight syringe ensures that your sample is kept in a controlled environment, which is crucial for reliable results.
Consistent Pressure Minimizes Sample Splattering
Low-viscosity samples especially are very sensitive to static, or “beading” along a metal needle shaft. Without a gas-tight, vacuum-like environment, this risks ‘splattering’ your sample due to instability in consistent pressures during withdraw and injection. WPI’s NanoFilÔ syringes are low volume, gastight syringes that are popular for a wide variety of microinjection applications.
Minimize External Contamination
A gas-tight syringe makes certain that no outside gases and/or toxins enter the system, that risks modifying the makeup of the sample being delivered.
Improve Consistency by Controlling Atmospheric Conditions
Maintaining the consistency and integrity of a sample is critical in any sensitive study. If a syringe is not gas-tight, the sample could be exposed to atmospheric conditions, leading to potential changes in pressure, volume, or concentration.
Stable Pressure for Better Accuracy
For accurate delivery, small deviations in volume or pressure can result in notable errors. A gas-tight syringe supports accuracy and reproducibility of measurements by reducing confounding variables related to gas exchange.
Minimize Sample Evaporation
For volatile substances, a gas-tight syringe inhibits evaporative processes, which could result in a reduction in sample volume and, ultimately, an inaccurate volume delivered.
Overall, a gas-tight syringe system is essential for warranting the precise overall outcome of your sample delivery, throughout the entirety of your study. NanoFil™ is a truly gas-tight, ultra-precise microliter injection system! In addition, NanoFilÔ needles have a 1:1 contact with the syringe plunger, for a truly zero dead volume system. NanoFilÔ needles are available in a variety of gauge sizes, from 33G down to 36 gauge, the smallest needle gauge commercially available. When precision is critical, researchers trust WPI’s NanoFilÔ GasTight Injection Systems.
