Installing Thermostatting Tubing to Cellholders
All cuvette holders supplied for use with the LS 55 are thermostattable using
circulating water:
• The cuvette holders are made watertight with a sealant that is guaranteed up
to 60
° C.
• Higher temperatures may make the sealant leak, in which case you should
replace it with a suitable sealant with higher temperature specification.
• At temperatures below 15 ° C, condensation may occur on the surfaces of the
cuvette. If this is the case, either purge the sample area with dry air, or lead
dry air onto the cuvette surfaces using tubing.
To fit the thermostatting tubing:
1. Route the tubing into the sample area and onto the two tubing ports under
the sample area door, as shown in Figure 23.

2. The tubing is then brought around the outside of the accessory bracket, as
shown in Figure 24.
