Brand: scuvette. 1mm quartz stoppered short path cuvette, four-way (four sides clear), 350μL volume. Japanese imported JGS1 fused silica, optical contact one-piece molding, >83% transmittance, 200nm-2500nm wavelength range, max operating temperature 1200°C. Outline dimension 12.5 × 3.5 × 45 mm, wall thickness 1.25mm. Supplied with PTFE stopper. Acid, alkali and organic solvent resistant.
4-Port or Two-Way? How to Choose
Both versions share the same 1 mm path length, 350 μL volume, JGS1 fused silica body and optical contact one-piece molding. The only difference is how many side walls are optically clear: the 4-Port cell is polished on all four walls, the Two-Way cell on two opposite walls only.
| | 4-Port (this page) | Two-Way |
|---|
| Clear faces | All four side walls | Two opposite walls |
|---|
| Best for | Setups where the cell orientation is not fixed, right-angle (90°) detection geometry, or one cell shared between instruments with different beam paths | Standard UV-Vis absorbance readings through a fixed beam path |

| Path length | 1 mm | 1 mm |

| Volume | 350 μL | 350 μL |

| Window material | JGS1 fused silica, 190–2500 nm | JGS1 fused silica, 190–2500 nm |

| Price | $175.00 | $138.00 |

If your spectrophotometer always reads through the same pair of faces, the Two-Way version does the same job at a lower price. Choose the 4-Port version when the cell may be rotated between measurements, when your method uses right-angle detection, or when several instruments share the same cell.

Good product, the finish is clean and the windows are clear. Shipping took a bit longer than expected but the cuvettes themselves are worth the wait.

Excellent product. The optical contact process ones are comparable to German brands at a fraction of the cost. Our UV-Vis results are clean and reproducible.

Perfect for our UV-Vis applications. The quartz is clear, no bubbles or inclusions visible. Paired testing transmittance was within spec. Very satisfied.

1mm Quartz Stoppered Short Path Cuvette, 4-Port, 350µL – Frequently Asked Questions
What is the path length and sample volume of this cell?
Path length is 1 mm and the cell holds about 350 µL. A short path length keeps absorbance in the linear range for concentrated samples without diluting them.
Can I use strong acids, alkalis or organic solvents in it?
Yes. The body is Japanese JGS1 fused silica formed by optical contact one-piece molding, so there is no cemented seam to attack: the cell resists acids, alkalis and organic solvents. Only HF and hot phosphoric acid will etch quartz.
What temperature can the cuvette withstand?
Because it is a single piece of fused silica rather than an adhesive-bonded cell, the maximum operating temperature is 1200 °C. Remove the PTFE stopper before heating – it has a much lower limit.
Is a stopper included and what is it for?
Yes, a PTFE stopper is supplied with the cell. It closes the fill port so volatile samples do not evaporate during a run. Cleaning and handling guidance is in our cuvette care guide.
