1ml Borosilicate Glass Syringe with Stainless Steel Plunger

Glass syringes give you repeatability that plastic can't match. The borosilicate barrel won't absorb or react with essential oils, viscous concentrates, or lab-grade liquids, and the graduations stay visible even after dozens of uses.

What's Included

• One 1ml borosilicate glass barrel
• Stainless steel plunger with rubber tip
• Luer-lock adapter (if applicable to variant)
• Protective cap or case (where applicable)

Key Features

• Borosilicate glass barrel: Lab-grade, chemically inert. No leaching, no reactions with oils or solvents. Graduations printed and fused into the glass.
• Stainless steel plunger: Smooth, consistent draw across the full 1ml range. Rubber tip seals against the barrel walls with minimal friction.
• Luer-lock tip: Standard medical-grade threading accepts needles, filters, or other luer-compatible attachments.
• Precision graduations: Clear 0.1ml markings make it easy to measure small volumes repeatably. Ideal for concentrate dosing, resin mixing, or essential oil application.
• Durable construction: Glass and stainless steel last for years with basic care. Autoclavable for sterile reuse in lab settings.

Applications

• Concentrate and resin dosing: Measure exact volumes of epoxy, UV resin, or botanical concentrates without waste or guesswork.
• Essential oil application: Dispense precise amounts of oils into roller bottles, diffusers, or cosmetic formulations. One drop at a time, no spilling.
• Lab and scientific work: Sample collection, titration, or liquid transfer where contamination or absorption would skew results.
• Micro-measurements: Diamond painters, jewelry makers, and crafters who need sub-milliliter precision for adhesives, glazes, or pigments.
• Pharmaceutical formulation: Mixing small batches of topicals, tinctures, or custom compounds that require accurate ratios.
• Aquarium or hydroponics: Precise dosing of additives, supplements, or treatments in confined tank systems.

How to Use (Step-by-Step)

1. Draw back the plunger to the 1ml mark to create negative pressure. This primes the barrel and removes any air pockets.
2. Insert the needle or luer-lock adapter (if needed) into the tip and twist clockwise until snug. don't over-tighten.
3. Pierce the container cap or liquid surface with the needle. Draw the plunger back to fill the barrel to your desired volume.
4. Check the liquid level against the printed graduations. Adjust by drawing or pushing slightly to reach the correct mark.
5. Remove the needle (if applicable) and dispense the liquid by pressing the plunger smoothly and steadily.
6. After use, rinse immediately with distilled water if the syringe held oils or sticky substances. Allow to air-dry completely before storage.
7. For sterile reuse, autoclave at 121°C for 15 minutes, or hand-wash and allow to dry in a clean, covered container.

A 1ml borosilicate glass syringe with stainless steel plunger and luer-lock tip, marked in 0.1ml increments, autoclavable, and chemically inert for precise dosing of oils, resins, and lab liquids.

Compared to Alternatives

Plastic syringes are cheaper but absorb odors and oils, and the graduations fade quickly with repeated use. Metal syringes are opaque, so you can't see the liquid level without emptying them. Glass offers visibility, durability, and complete chemical inertness. Compared to measuring cups or droppers, a syringe gives you sub-milliliter accuracy and repeatable delivery, especially important when dosing concentrates or mixing resin compounds that require exact ratios.

Frequently Asked Questions

Can I use this syringe with a needle?

Yes. The luer-lock tip accepts standard needles (18g, 20g, 22g, etc.). Twist the needle hub clockwise until it seats, it shouldn't slip when gentle downward pressure is applied.

How do I clean a syringe after using it with thick liquids?

Rinse immediately with warm distilled water and, if needed, a small amount of isopropyl alcohol (70%) to dissolve residue. Use a syringe brush if available. Never let thick liquids dry inside the barrel, they'll harden and jam the plunger.

Is this syringe sterile out of the box?

No, it ships clean but non-sterile. For sterile use in lab or pharmaceutical settings, autoclave at 121°C for 15 minutes before use.

What's the difference between luer-lock and luer-slip tips?

Luer-lock has threads and requires a twist to attach the needle. Luer-slip simply pushes on. Our syringes use luer-lock for a secure, no-slip connection.

Can I use this syringe to measure or dispense food-grade oils?

Yes, but wash immediately after use. Borosilicate glass is inert and safe for food oils. However, if the syringe will be reused for lab chemicals, wash thoroughly and rinse with distilled water to avoid cross-contamination.

What happens if the plunger gets stuck?

Soak the syringe in warm distilled water for 10, 15 minutes to soften any residue. Gently work the plunger back and forth. If it remains stuck, don't force it, contact us for a replacement.

Care & Storage

Clean immediately after use with distilled water. Store in a clean, dry location away from direct sunlight. Keep the plunger and barrel together (don't disassemble). For long-term storage, wrap the syringe in a clean cloth or store in a sealed container to prevent dust accumulation. Never store with the plunger fully compressed, leave it at the 0.5ml mark to prevent seal deterioration.

Shipping & Returns

Ships within 1, 2 business days from our US warehouse. We offer 30-day returns on unopened items. Syringes used for sterile or compounding work can't be returned; contact us first if you've questions about suitability for your use case.
