Description

Similar in all respects to the Type 9 Semi­ Micro cells, with the exception that these cells are supplied with a PTFE stopper, or stoppers as pictured, to fit in a ground fitting to reduce evaporation of volatile samples (The Type 29B comes with stoppers even though the stoppers are not pictured). The Type 29 and Type 29B cells have an external height of 48 mm plus stopper.

Smaller sample volumes can be achieved by using cell Type 29/9 or 29B9 with a 9mm instead of a 3mm thick base.

Note: Cells with a 9mm base are not suitable for an instrument with an 8.5mm 'Z' dimen­sion.

Short Pathlength Spacers

Black anodized aluminum spacers are available in three sizes for use with 1, 2, and 5mm path length cells, supporting them in a normal 12.5 x 12.5mm holder where there is no cell holder path length adjustment facility. SPA-1 (1mm), SPA-2 (2mm), SPA-5 (5mm).
