Analytical precision in chromatography is inextricably linked to the accuracy of sample injection. LabFriend provides a premier selection of microlitre syringes, located within the syringes section of our chromatography department. These precision-engineered instruments are designed to deliver exact volumes of liquid or gas samples into GC and HPLC inlets with exceptional repeatability.
Why Choose Professional Microlitre Syringes?
Our curated collection of analytical syringes is designed for high chemical resistance, minimal dead volume, and long-term plunger durability:
- Specialized RN (Removable Needle) Models: We stock Hamilton Microliter Syringe 75RN (5 µL) and 702-RN (25 µL) versions, allowing for easy needle replacement if damage occurs or for switching between different needle gauges.
- High-Volume Gastight Options: Utilize the Hamilton Microliter Syringe 1001 LTN, featuring a 1 mL capacity and PTFE plunger tip to ensure a leak-proof seal for both liquid and gas samples.
- Precision Cemented-in Needles: Explore the Hamilton Central Mikroliter Syringe range (702-N and 800 series), designed with fixed needles for reduced carryover and maximum structural integrity during routine manual injections.
- Ultra-Low Volume Analysis: Our range includes the Hamilton Type 7001-KH (1.0 µL) syringe, engineered specifically for high-sensitivity applications requiring sub-microlitre accuracy.
LabFriend supplies microlitre syringes from manufacturers trusted globally for analytical excellence:
- Hamilton: The industry standard for liquid handling precision, offering the 700, 800, and 1000 series syringes for professional chromatography.
- Trajan Scientific (SGE): Experts in separation science components, providing high-performance syringes optimized for both manual and autosampler use.
- Socorex: Renowned for Swiss precision in pipette and syringe manufacturing, offering robust solutions for demanding laboratory environments.
- Poulten & Graf: Providers of high-quality glass syringes and laboratory essentials designed for durability and accuracy.
- LLG Labware: Offers a cost-effective range of reliable microlitre syringes for routine sample preparation and education.
Accurate injection is the start of every successful run; to further enhance your chromatography workflow, we recommend exploring these related categories:
- Syringe Filters: Ensure your samples are particulate-free before loading them into your precision Hamilton syringes.
- HPLC Columns: Deliver your precise sample volumes into high-performance analytical columns for optimal resolution.
- Disposable Syringes: Ideal for bulk fluid transfer and initial sample preparation where high-cost precision syringes are not required.
- Viscometers: Measure sample viscosity to ensure correct syringe plunger speed and avoid cavitation during aspiration.
Unsure whether a Gastight or Microliter series syringe is better for your specific mobile phase? Our team provides local technical support to help you find the perfect precision solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. What is the difference between Hamilton Microliter and Gastight syringes?
Microliter syringes (like the 700 series) use a stainless steel plunger hand-fitted to the glass barrel, while Gastight syringes (like the 1000 series) feature a PTFE plunger tip for a superior seal with gases and volatile liquids.
2. Why choose a Removable Needle (RN) over a Cemented Needle (N)?
RN syringes allow you to replace a bent needle without discarding the expensive syringe barrel, and they offer the flexibility to use different needle lengths or tip styles (point styles).
3. What does "KH" stand for in the 7001-KH model?
"KH" stands for Knurled Hub, a specialized design that allows for the precise replacement of the plunger and needle assembly in ultra-low volume syringes.
4. How should I clean my precision microlitre syringe?
Syringes should be rinsed immediately after use with a solvent that dissolves the sample, followed by a high-volatility solvent like acetone, and dried with clean air or vacuum.
