Description

C121WS is a JGS1 quartz reflectance sample cell for reflectance measurements that use a small open sample cup. Its cylindrical 12 mm outer diameter and 20 mm body height give you a compact body to place in a matching holder, while the open top lets you load, level and inspect the sample surface directly before measurement.

This SKU also uses a powder-fused quartz construction. In practical use, that matters less as a marketing grade than as a body style choice: it suits an open sample cup that is handled from the top, cleaned directly at the sample area and selected for exposed-surface work rather than for sealed flow or pressure arrangements.

Choose this option

Choose C121WS when your method is built around an exposed sample surface and your fixture accepts a 12 mm cylindrical body. This format is useful for powders and other samples that need to be placed in the cup, adjusted at the surface and measured without a cap, tubing connection or internal flow path.

What makes this option different

Open-top cup: sample access is direct from above, which helps when you need to place, level or remove the material in the cell itself.
Reflectance-use format: this cell is intended for reflectance measurements rather than a closed transmission path arrangement.
Powder-fused quartz construction: a quartz cup construction suited to direct sample contact and top-down cleaning in this open-body format.
12 mm outer diameter: an important fit point for holders or recesses designed around a smaller cylindrical cup.
20 mm body height: useful when checking vertical seating and nearby clearance in a compact accessory space.
1 mm wall thickness: a body detail worth checking if your holder, clamp or surrounding recess fits closely around the outside wall.

Using this cell

Load the sample from the top and prepare the exposed surface as required by your method. For loose or granular material, it is often helpful to settle the sample gently and leave a stable, even surface before placing the cell in the measurement position.

This is an open cell body. It is better suited to bench handling and direct loading than to applications that need a sealed closure, transport after filling, tubing connections or pressure-rated use.

First-use check

Inspect the rim and body for chips, scratches or residue before first use. Place the empty cell in the intended holder to confirm seating and top access, then run your normal blank or reference routine before measuring samples.

Fit and optical alignment

Check the holder for a 12 mm cylindrical body and 20 mm uncapped height. Because the sample is accessed from above, also leave enough clearance for filling tools, fingers or other handling around the rim.

Z Height is not established for this SKU. If your reflectance accessory depends on a defined beam-center position or a fixed sample-surface height, verify that geometry in your own holder before ordering.

Solvents and cleaning

This quartz cell is described for contact with acids, alkalis and organic liquids, but the operating conditions are not specified here. Match the cell to your actual sample and cleaning chemistry instead of treating that statement as an unrestricted compatibility list.

Do not use hydrofluoric acid on quartz. Avoid hot strong alkalis and abrasive cleaning. For general background on quartz cell constructions, see Compare fabrication methods.

Included with this option

Supplied as 1 reflectance sample cell. A closure or other accessories are not established for this listing.
