precision glass coils used in the manifold are chemically inert and help
the user to check the flow at a glance.

Specially developed for tobacco analysis, these Bran+Luebbe multitest methods enable you to measure several different parameters with one analytical cartridge or manifold. When changing from one test to another only the reagents and the colorimeter filter need to be changed.
Multitest methods are ideal for laboratories with small to medium workloads, or where some tests are required
only occasionally, as there is no need to invest in a sepa-rate manifold for each chemistry.
The MT24 and MT26 multitest methods for tobacco
analysis incorporate a dialyser to eliminate interference
from colored samples. MT25 is used with an on-line dis-tillation unit to give fully automatic analysis.
Ranges can be varied by changing sample pump tubes. SEAL ANALYTICAL, INCSEAL ANALYTICAL, INC. · MEQUON TECHNOLOGY CENTER · 10520-C BAEHR RD · MEQUON, WI 53092
