Introduction
Thank you for choosing this Histology Bath. Its low working temperature (-60°C / -76°F) freezes
samples quickly, preventing microscopic ice crystals from developing and samples from distorting. It
is ideal for fast-freezing tissues for enzyme studies. The Histology Bath is not a controlled cooling
source; it is designed to run at maximum cooling.
Standard features include:
• Continuous cooling to -60°C / -76°F
• 1.9 liter stainless steel reservoir and reservoir cover
• Immersion basket and chuck holder
• Front-mounted reservoir drain
• DuraTop™ insulating top deck

Safety Recommendations
To prevent injury to personnel and/or damage to property, always follow your workplace’s safety
procedures when operating this equipment. You should also comply with the following safety
recommendations:
WARNING: The Histology Bath uses isopentane as the bath fluid. Due to the flammability of
this liquid, always use the Histology Bath under a fume hood.
WARNING:
• Always connect the power cord on this Histology Bath to a grounded (3-prong) power outlet.
Make certain that the outlet is the same voltage and frequency as your unit.
• Never operate the Histology Bath with a damaged power cord.
• Always turn the Histology Bath Off and disconnect mains power before performing any
maintenance or service.
WARNING:
• Never operate the Histology Bath without bath fluid in the reservoir. Periodically check the
reservoir to ensure that the liquid depth is within acceptable levels. Always refill the
reservoir using the same bath fluid type that is already in the reservoir.
• Use compatible bath fluids only.
• Always drain all fluid from the reservoir before moving or lifting your Histology Bath. Be
sure to follow your organization’s procedures and practices regarding the safe lifting and
relocation of heavy objects.
WARNING: Always allow the bath fluid to return to ambient temperature before draining.
WARNING: It is the user’s responsibility to properly decontaminate the unit in the event
hazardous materials are spilled on exterior or interior surfaces. Consult manufacturer if there
is any doubt regarding the compatibility of decontamination or cleaning agents.

confirm proper operation. Beyond one week, your unit may be warranty repaired, but not replaced.
If the unit is damaged or does not operate properly, contact the transportation company, file a
damage claim, then contact the company where your unit was purchased.
WARNING: Keep unit upright when moving. Be sure to follow your company’s procedures and
practices regarding the safe lifting and relocation of heavy objects.

Installation
Your Histology Bath is simple to setup and install. The only tool required is a container for adding a
suitable fluid to the bath reservoir.
General Site Requirements
WARNING: The Histology Bath uses isopentane as the bath fluid. Due to the flammability of
this liquid, always use the Histology Bath under a fume hood.
Locate your Histology Bath on a level surface in an area that is free from drafts and wide ambient
temperature variations, such as near heater or air conditioning vents. Do not place it where there
are corrosive fumes, excessive moisture, or in excessively dusty areas.
Position the unit to allow for unobstructed air flow through the side and rear vents. A space of at
least 4 inches (10.2 cm) should be provided behind the unit.
Avoid voltage drops by using properly grounded power outlets wired with 14 gauge or larger
diameter wire and if possible, be close to the power distribution panel. The use of extension cords is
not recommended; this will reduce the potential for problems caused by low line voltage.
Adding Liquid to the Bath Reservoir
WARNING: Fill reservoir with fluid before applying power to the unit.
WARNING: Read the safety data sheet for the bath fluid being used carefully before filling
reservoir.
The Histology Bath is designed for use with isopentane (also known as 2-methlybutane).
Fill bath so that the liquid level is approximately 1 inch (2.54 cm) from the top for best refrigeration
performance. Be sure to allow for the fluid displacement that will result when the immersion basket
and samples are placed in the reservoir.
WARNING: Always drain all fluid from the reservoir before moving or lifting your Histology
Bath. Be sure to follow your organization’s procedures and practices regarding the safe lifting
and relocation of heavy objects.
WARNING: To avoid the potential for burns, allow the Histology Bath to return to ambient
temperature before cleaning or performing any maintenance.
Electrical Power
WARNING: The Histology Bath’s power cord must be connected to a properly grounded
electrical receptacle. Make certain that this electrical outlet is the same voltage and frequency
as your unit. The correct voltage and frequency for your Histology Bath are indicated on the
identification label on the rear of the unit.
CAUTION: The use of an extension cord is not recommended. If one is necessary, it must be
properly grounded and capable of handling the total wattage of the unit. The extension cord
must not cause more than a 10% drop in voltage to the unit.
Plug the Histology Bath’s power cord into a properly grounded electrical outlet of the correct
voltage and frequency.

Normal Operation
WARNING: Due to the flammable nature of isopentane, the Histology Bath should always be
used under a fume hood. Be sure to wear appropriate protective equipment, such as splash
goggles and gloves.
NOTE: The Histology Bath operates at maximum cooling performance.
Place the Power Switch / Circuit Breaker on the front of the Histology Bath in the On position. The
compressor will start up and the unit will begin cooling. It will take about one hour for the unit to
achieve a -60°C / -76°F working temperature.
Once the unit has reached working temperature, remove the reservoir cover and slowly submerge
the immersion basket in the reservoir. Use the tissue mounts (not supplied) and chuck holder to
position the samples properly in the sample basket. Replace the reservoir cover.

Routine Maintenance & Troubleshooting
WARNING: Hazardous voltages may be present. Disconnect power before performing
maintenance.
Draining the Reservoir
To drain fluid from the bath, attach a short length of suitable 11.5 mm ID / 0.45 inch ID tubing to the
drain port and secure it using a hose clamp with a minimum ID of 18 mm / 0.7 inch. Open the drain
valve using a flat blade screwdriver. When closing the valve, do not over tighten.
WARNING: Be sure to close the drain valve before refilling the bath reservoir. Do not over
tighten.
Cleaning the Bath
Thoroughly clean the bath before each use. Use only mild soap and water when cleaning. Do not use
steel wool as damage to the unit may result. Non-steel scouring pads are acceptable.
The entire unit is housed in a tough, well-insulated stainless steel casing that is corrosion and
chemical resistant.
Air Vents
The unit draws air through the rear and exhausts it through the side vents. The vents should be
inspected regularly for the accumulation of dust and cleaned as required.
Air Filter
To keep the refrigeration system operating at optimum cooling capacity, the reusable filter located
at the rear of the unit should be kept free of dust and dirt. It should be checked on a scheduled basis
and cleaned as required.
To access the air filter, remove the three screws securing the grille cover to the unit’s housing,
detach the grille, and then gently remove the air filter from the filter compartment. Use a mild
detergent and water solution to wash off any accumulated dust and dirt and then rinse and dry
thoroughly before reinstalling.
