Always observe the following safety precautions:
•Use only as specified by the operating instructions or the intrinsic protection may
be impaired. After transport or storage in humid conditions, dry out the unit
before connecting it to the supply voltage. During drying out the intrinsic
protection may be impaired.
•Connect only to a power supply with a voltage corresponding to that on the serial
number label.
•Connect only to a power supply that provides a safety ground terminal.
•Before moving, disconnect at the power supply socket.
•To reduce the risk of eye injury during high temperature operation, use safety
goggles or spectacles.
•Do not touch surfaces that become hot during high temperature operation.
•Ensure that the operating temperature is less than the maximum operating
temperature of your sample material.
•Ensure that the power switch is easily accessible during use.
•If liquid is spilled inside the unit, disconnect it from the power supply and have it
checked by a competent person.
•It is the user’s responsibility to carry out appropriate decontamination if
hazardous material is spilled on or inside the equipment.

2. Product Information
The Boekel Round Tissue Bath is designed as an economical and efficient tissue floatation
bath for use in mounting tissue specimens to glass slides.
The Round Tissue Bath has an 8.5” (21.6cm) diameter by 2” (5cm) deep-water chamber
with a 1.25” (3.2cm) wide rim for slide warming and drying. The Tissue Bath has a water
temperature range of ambient + 10°C to 65°C under normal operating conditions.
3. Assembly
3.1 Unpacking
Remove packing materials carefully, and retain for future shipment or storage of the unit.
Inspect for damage. Report all shipping damage to the carrier immediately. Shipping
damage is covered by the carrier and repair/replacement for shipping damages must be
coordinated through the carrier. Complete and return the Warranty Registration Card.
Packs should contain:
•Round Tissue Bath
•Operating Instructions
•Bath Cover
•Thermometer Holder
3.2 Installation
Place the Round Tissue Bath on a flat and stable surface, preferably away from drafts.
Plug power cord into a power supply that matches the voltage listed on the serial number
label on the rear of the unit.
4. Operation
4.1 Controls and Indicator Lamp
The Power Switch controls power to the unit.
The heater lamp is on continuously while the bath is heating up. As the required
temperature is approached, it starts to flash. When the bath is controlling at the set
temperature, the heater lamp flashes intermittently.
4.2 Setting the Temperature
To increase bath temperature, rotate the thermostat knob in the clockwise direction. To
decrease bath temperature, rotate the thermostat knob in the counterclockwise direction.
Allow about 60 minutes for the bath to equilibrate from a cold start. A thermometer may
be used to check exact bath temperature. Allow 5 to 10 minutes for the bath to re-
equilibrate when adjusting the bath temperature from a previous set point. If the bath is
to be operated at the same temperature in the future, the thermostat setting should not be
disturbed. Just turn the bath off using the On/Off switch.

4.2 Filling the Bath
Fill the bath with water. Always keep at least 3/4” (1.9cm) of water in the bath. Do not
let the bath run dry as heater damage may result.
