Crossing Upgrade Cartridge Filling Machine 50ml Capacity
This handheld semi-automatic system uses a heated syringe and an annular heat barrel to deliver oil with controlled smoothness. It can fill up to 50 units of 1 ml in about 5 minutes, and oil changes take roughly 60 seconds. The dial gives easy 1 ml increments for precise dosing. Best for small-batch producers who want measured fills without direct contact heating. A key advantage is oil protection, as the design heats oil without exposing it to heating elements directly.
- Best for compact studios needing quick, accurate fills
- Better for oils that may burn with direct heating
- Limitations: Requires careful handling of the heated system and regular cleaning to prevent residue buildup
Cartridge Filling Machine Handheld Portable Semi Auto
This device emphasizes precision with a readable dial set to 1 ml increments and a dosed stainless steel piston with a no-drip luer lock tip. It fills quickly—up to 50 units of 1 ml in five minutes—while maintaining oil integrity via the annular heat barrel. It suits small operations that require dependable manual control and easy volume adjustments. It pairs portability with a robust drive for consistent dosing across batches.
- Best for mobile filling tasks and small batches
- Better for users needing straightforward 1–5 ml dosing
- Limitations: May require manual effort for larger volumes or high-throughput needs
Proshine Cartridge Filling Gun 50ML（110V）
The Proshine model offers a large 50 ml barrel with a minimum 1 ml setting and 1–5 ml dosing options. It includes multiple lure lock needle sizes—12, 13, 14, 15, and 16—with two needles per size. Upgraded heat pad uses fast conduction to warm the oil thoroughly while protecting it from direct contact with heating elements. This configuration is ideal for users who require continuous filling with multiple nozzle options and reliable heating.
- Best for users needing multiple needle configurations
- Better for frequent small-dosage fills with a warm barrel
- Limitations: Requires compatible luer lock accessories and proper cleaning to maintain accuracy
Handheld Semi Automatic Grease Injector Filler Gun
This handheld filler is designed for quick dosage in semi-automatic mode. It emphasizes portability and simple operation for cartridges, though it is labeled for grease, its filling mechanism is similar to cartridge fillers and can suit non-oil fill tasks with appropriate viscosity. Best for a compact tool that doesn’t require a fixed setup, especially when budget constraints exist. Use caution with viscosity limits and ensure compatibility with your oil or gel type.
- Best for budget-conscious buyers needing a compact tool
- Better for light to moderate viscosity materials
- Limitations: Not all greases or oils may be compatible; confirm with material compatibility before use
Hanchen Peristaltic Bottle Filler (2 Head)
This two-head peristaltic filler offers high precision for small bottles. It is ideal for cosmetics and essential oil solutions requiring accurate dosing with cleanable tubing. The system maintains hygiene by ensuring the liquid only contacts the tubing, which is easy to replace. It is best for users who bottle small volumes and prioritize cleanability and consistent accuracy.
- Best for small-bottle cosmetic or oil products
- Better for cleanability and hygiene with separate tubing
- Limitations: Peristaltic systems may be less suited for very viscous materials; tubing compatibility matters
Buying Guide
What should you look for when choosing a cartridge filling machine?
- Capacity and throughput: Choose 50 ml-capacity options if you regularly fill small volumes and want batch-ready speed.
- Precision features: Dial-in volume increments (1 ml steps) helps maintain consistent dosing across units.
- Heating method: Heated syringes and annular heat barrels protect oils from scorching and preserve flavor and potency.
- Needle and accessory options: Multiple needle sizes and luer-lock compatibility enable flexibility with cartridge types.
- Hygiene and cleaning: Independent tubing and easy cleaning reduce cross-contamination for cosmetic or oil-based fills.
- Portability vs. fixed setup: Handheld tools suit on-the-go tasks; larger or table-mounted units suit high-throughput operations.
