Biological contamination occurs only when specimens slough off the slides during staining. These tend to be removed by
the continual flow of reagents through the instrument. In addition, the reagents used in the staining and cleaning process
are suitable for low to intermediate level disinfection. The stainer is self-cleaning under normal use, but cannot be
considered decontaminated. The stainer exterior can also be contaminated by touching with contaminated gloves and
requires routine surface cleaning.
For additional decontamination, the following procedures provide low to intermediate disinfection. If the stainer is
contaminated by unusually hazardous or disinfection resistant organisms, further treatment with appropriate procedures
may be necessary. If sending the stainer to Wescor for service or repair, contact Wescor for current decontamination and
shipping instructions.
1. Mask the lid latch and locking pin holes with waterproof tape to protect the stainer Interior.
2. Place the stainer in a biological safety hood or well-ventilated area. Use prudent safety precautions including hand
and eye protection.
CAUTION! Do not flood the stainer bowl by overloading the drain. Never allow fluid to rise above
the base of the drive hub. Do not spray fluids near openings in the stainer housing that lets fluid
into the instrument interior. This can cause severe damage.
3. Spray inner bowl and inner lid with disinfectant detergent such as a 10% bleach solution or Wescor’s
Decontamination Solution (SS-133).
4. Repeat spray treatment every 2 or 3 minutes. Leave solution on surfaces for approximately 10 minutes. Do not allow
cleaning solutions to dry on the stainer surfaces.
5. Rinse inner bowl and lid thoroughly with tap water.
6. With the stainer lid closed, apply decontamination solution to a cloth. Wipe the exterior surfaces of the stainer. Do
not flood the display panel with excessive moisture. Any moisture that seeps through could damage the internal
electronics. Repeat wipe down every 2 or 3 minutes for about 10 minutes total.
7. Remove decontamination solution by thoroughly wiping surfaces with a cloth soaked in tap water.
8. Immerse or generously spray the carousel and lid with disinfectant detergent. Allow to sit for 20 to 30 minutes. Do
not autoclave the carousel or lid.
9. Thoroughly rinse the carousel and lid with tap water.
NOTE: These decontamination procedures are for routine use only. If shipping the stainer to Wescor for
repair or service, contact Wescor ’s Service department for a current copy of the decontamination and
shipping instructions before preparing and shipping the stainer. Shipping stainers without
decontaminating them according to these instructions is dangerous to service personnel and results in a
significant decontamination charge.
