OsmoTECH XT Single-Sample Micro-Osmometer User Guide

8.4  Maintenance

Keep your OsmoTECH XT clean on the exterior and free 
of spills, debris, and dust.

• 

Periodically wipe the instrument with a barely-damp 
cloth. Use either warm soapy water or isopropyl 
alcohol to dampen the cloth.

• 

Make sure the fan on the back has not accumulated 
dust and debris that could impede air flow. Dirty air 
vents can cause instrument overheating and reboots.

Complete other service to your OsmoTECH XT following 
instructions in this section.

Chamber cleaning

If you experience multiple Sample Pre-freeze errors, or if 
you suspect contamination of the sample probe, clean 
the cooling chamber with a chamber cleaner that has 
been dampened with water or a cleaning solution for 
protein removal. (Thermo Scientific Orion Cleaning 
Solution, part number 900021 is recommended.).

• 

If the plunger shows signs of fouling, clean it with a 
lint-free cloth dampened with isopropyl alcohol or 
a cleaning solution for protein removal. (Thermo 
Scientific Orion Cleaning Solution, part number 
900021 is recommended.) 

Solenoid maintenance

A dirty solenoid can cause 

Sample Did Not Freeze

 errors 

and can affect instrument accuracy and repeatability.

If you suspect the solenoid function has degraded, follow 
the instructions below to inspect, clean, or replace it.

You should also clean the solenoid periodically as part of 
routine maintenance:

• 

If the instrument is used daily:

 Clean the solenoid 

monthly.

• 

If the instrument is used only occasionally:

 Clean the 

solenoid every three months.

This area of this instrument comes into contact 

with biohazardous materials. Take appropriate 

precautions.

1. 

Open the section of instrument housing above the 
cooling chamber to access the solenoid in the 
OsmoTECH XT.

2. 

Insert a disposable chamber cleaner into the sample 
probe opening until you feel a positive stop.

3. 

Unscrew the two solenoid retainer bracket screws and 
gently remove the bracket.

4. 

Being careful not to lose any small parts, grasp the 
enclosed solenoid plunger assembly, lift it up, and 
then withdraw it from the body cylinder.

NOTE: 

Leave the body cylinder in place inside the 
instrument.

5. 

Dampen the wooden end of a cotton-tipped 
applicator with a 70% isopropanol solution; then 
insert it down through the solenoid body into the 
smaller diameter plunger hole until it reaches the 
chamber cleaner you inserted in step 2.

Move the applicator in and out to scrub the sides of 
the hole. 

6. 

Clean the smaller diameter plunger of the solenoid 
assembly with a 70% isopropanol solution on a soft 
cloth.

Do not use any abrasive for this cleaning 
procedure.
