Pump Tubing and Cannulas
CAUTION
Use only the Hematek Pump Tube Set with the Hematek Slide Stainer. Use of other tubing
may result in incorrect measurement and improper staining, buffering, and rinsing.
The pump tubing is provided as a set of three separate pieces of tubing. Notice that each
pump tube is identified with a number and symbol, which corresponds to the reagent
carried by the tubing:
•
1
for stain
•
2
for buffer
•
3
for rinse
Each tube has a clear plastic cuff that fits snugly up to the pump arm and holds the tube in
position without slippage. The tubing is a special type of rubber that is resistant to
leaching and brittleness. The special diameters and lengths of the tubing assure precise
measurement of solutions. Each pump tube is connected to a cannula that is inserted into
the appropriate bottle in the Stain Pak. Three cannulas are provided with the Hematek
Slide Stainer. With proper routine cleaning, the cannulas can be used for an extended
period of time.
