Household Glassware Machinery
SM-J5 automatic glass test tube machine for Pyrex and soda lime glass. Produces dome or flat bottom tubes, 2 per cycle. Three models covering Φ10–32mm diameter. Output 3,750–6,000 pcs/h. Connects to inline annealing oven.
The SM-J5 Glass Test Tube Machine is an automatic production system for manufacturing precision glass test tubes from glass tubing. It handles both Pyrex (high borosilicate) and soda lime glass without requiring tooling changes, and produces either dome-bottom or flat-bottom test tubes. Each input tube yields two finished test tubes. Three models — A, B, and C — cover tube diameters from Φ10mm to Φ32mm, making the SM-J5 suitable for a wide range of laboratory and medical test tube specifications.
| Model | Tube Diameter (mm) | Length (mm) | Output (pcs/h) | Power | Gas Consumption | Oxygen | Dimensions (m) | Weight (kg) |
|---|---|---|---|---|---|---|---|---|
| A | Φ10–15 | 75–202 | 6,000 | 1.5 kW | 1.8 kg/h | 22 L/h | 2.80 × 1.20 × 1.35 | 650 |
| B | Φ16–25 | 75–202 | 5,400 | 1.5 kW | 2.5 kg/h | 34 L/h | 3.20 × 1.15 × 1.25 | 1,050 |
| C | Φ26–32 | 75–202 | 3,750 | 1.5 kW | 2.9 kg/h | 40 L/h | 3.60 × 1.25 × 1.45 | 1,380 |
Yes — the SM-J5 switches between dome-bottom and flat-bottom profiles without changing any tooling or parts. This is a key advantage for manufacturers producing multiple test tube types on the same machine.
Standard lead time is 40 working days from order confirmation, as each machine is manufactured to order. For custom or modified machines, allow approximately 60 working days. Contact us for a specific timeline based on your requirements.
Yes — specifications including tube diameter range, output speed, and additional processing functions can be modified to meet your production needs. Visit our Custom Orders page to discuss your requirements with our engineering team.
