As may be aware the main global manufacturer of 1% fluorescein strips Bausch and Lomb ceased manufacture leading to a loss of supply to the world several years ago
We currently have in stock a CE approved product called Fluo Glo (1% fluorescein strips) and can supply this product to opticians and Ophthalmic Medical Practices
Each Strip is a dry, white piece of
paper, one end of which is rounded
and is uniformly orange-red in color.

parameter
Overall length: 60 mm + 1 mm
Each single Strip consists of two
parts:
a) Holding Paper:
Length: 45 mm * 1 mm and
width= 7 mm + 0.5 mm
b) Impregnated absorbent paper
(orange-red in color) having
rounded tip:
Length: 15 mm t 1 mm and
width: 5 mm t 0.5 mm
Overall length 60.0 mm
a) Holding Paper:
Length: 44.A5 mm
Width :7 mm

3. Identification
Cut a colored
Tip from 1 Strip,
Place it in a
small test tube
containing 1 mL
of water, and
agitate for
1 minute:
A: A solution of it is strongly fluorescent,
even in extreme dilution. The
fluorescence disappears when the
solutions is made acid, and
reappears when the solution is again
made alkaline.
B: Place one drop of a solution upon
a piece of filter paper: a yellow spot
is produced and, when exposed
while moist to the vapor of bromine
for 1 minute and then to ammonia
vapor, it becomes deep pink in color.
A: The fluorescence disappears
when the solution is made acid,
and reappears when the solution
is again made alkaline.
B: It becomes deep pink in color.
