A quartz crucible is a fused-quartz vessel that holds a sample while it is heated, for example for ashing or calcination in a muffle or tube furnace. Our standard crucibles come in ten sizes from 5 mL to 300 mL, can be used continuously up to 1,100 °C and for short periods up to 1,200
MQQCU013 is a 5 mm-path quartz cuvette with 0.5 mm optical walls. It is a useful starting point when a cell design needs to control both the liquid layer and the quartz in front of it. Those two dimensions affect different parts of the measurement and mounting arrangement.
MQQCU023 places a thin sample layer in a continuous groove inside a long, slender quartz body. The nominal path is 0.25 mm and the capacity is 65 µL. It is a different approach from filling an upright cuvette: the groove, its open ends and the observation position work together.
MQQCU021 combines a 10 mm sample path with a nominal 600 µL chamber, two upper connections and a bottom bore. The reduced sample region makes optical positioning important. The lower interface and the tubing above it give this cell a more specific installation layout than a plain square cuvette.
MQQCU016 provides a 1 mm sample path in a narrow quartz body with a rounded, thickened lower profile. The short gap is the optical choice; the rounded base is the mounting choice. Understanding both helps turn this unusual cuvette into a useful starting point for a custom holder or cell.
MQQMC081 opens into a grooved main plate and a separate cover. Its 8 × 10 mm recess is 0.8 mm deep, giving direct access to the sample area before the cover is placed. For powders or small solid specimens, that access is the main reason to consider this layout.
MQQCU010 is a quartz cell listed for contact-lens inspection, with 21 mm and 5 mm optical directions. Its wide, shallow chamber makes room for a specimen while offering different viewing distances. The useful starting question is how the lens will be placed, viewed and removed.
Use C0.51WS to discuss powder, film or solid placement, distinguish recess depth from surface location and define the drawing and checks for a custom change.
Plan C033SS illumination, collection and repeatable location, with separate project requirements for the triangular section, holder and optical information.
Use MQQFC119 to review the 40/5 mm path choice, access to both optical directions, side-port clearance and separately agreed checks.
