Overview

The Fisher Isotemp GPD10 is designed as a general-purpose laboratory water bath for applications requiring samples, containers, or reagents to be maintained at a controlled temperature.

Water baths provide indirect heating by transferring thermal energy from heated water to containers immersed in the reservoir. Because water surrounds much of the sample container, this approach can provide gentle and relatively uniform heating without the direct surface temperatures associated with a conventional hot plate.

The GPD10 combines a 10-liter stainless steel reservoir with an electronic temperature controller and 800-watt heater. Its combination of capacity, temperature range, and straightforward operation makes it suitable for a wide variety of routine laboratory workflows.

Key Specifications

Common Applications

The Fisher Isotemp GPD10 can support sample incubation, reagent warming, buffer preparation, media warming, temperature equilibration, thawing, enzyme-related procedures, microbiology workflows, clinical laboratory procedures, pharmaceutical research, quality-control testing, and other applications requiring controlled heating.

Its 10-liter reservoir provides enough room for multiple tubes, bottles, flasks, beakers, or other compatible laboratory containers, depending on their dimensions and the required immersion depth.

Unlike a shaking water bath, the GPD10 is intended primarily for static temperature control rather than applications requiring continuous sample agitation.

Ideal Laboratory Types

The GPD10 is suitable for biotechnology laboratories, pharmaceutical companies, biomedical research facilities, clinical laboratories, university research groups, microbiology laboratories, environmental testing facilities, industrial laboratories, quality-control departments, food-science laboratories, and general scientific research environments.

Its combination of a moderate 10-liter capacity and compact benchtop design makes it particularly useful for laboratories that need more working space than a small 2- or 5-liter bath without moving to a substantially larger 20- or 28-liter system.

Performance and Temperature Stability

Temperature stability and uniformity are important when selecting a laboratory water bath.

Fisher specifies temperature stability of ±0.1°C and temperature uniformity of ±0.2°C for the GPD10 under the manufacturer's stated test conditions.

Stability describes the bath's ability to maintain temperature over time once equilibrium has been reached. Uniformity describes how closely temperatures at different locations within the reservoir correspond to one another.

Actual performance can be influenced by operating temperature, water level, sample loading, container placement, ambient laboratory conditions, cover position, and the amount of time allowed for the bath to equilibrate.

Ambient to 100°C Temperature Range

The Isotemp GPD10 provides temperature control from ambient temperature up to 100°C.

This broad range supports both routine physiological-temperature applications and higher-temperature laboratory procedures.

Because the GPD10 is a heated bath rather than a refrigerated circulator, it cannot actively cool below ambient temperature. Applications requiring operation below room temperature require supplemental cooling or a refrigerated bath/circulator designed for that purpose.

The maximum practical operating temperature can also depend on laboratory conditions, fluid selection, evaporation, and use of the bath cover.

10-Liter Stainless Steel Reservoir

The GPD10 provides a 10-liter stainless steel reservoir with an internal work area measuring approximately 11.9 × 13 × 5.9 inches.

This relatively broad chamber provides flexibility when arranging different sample containers.

Stainless steel construction provides a durable, corrosion-resistant working surface and simplifies routine cleaning. Rounded reservoir corners further reduce areas where residue can accumulate.

Proper fluid selection and routine cleaning remain important for maintaining reservoir condition over time.

800-Watt Heating System

The GPD10 uses an 800-watt heating system to bring the bath fluid to the selected operating temperature and maintain it during use.

Heating time depends on the starting temperature, selected set point, fluid volume, sample load, cover position, ambient conditions, and electrical supply.

Using the supplied cover can help reduce heat loss and evaporation, particularly at elevated operating temperatures.

Digital Temperature Control

An electronic controller allows the operator to establish the desired bath temperature and monitor actual conditions through the front display.

The GPD10 displays both actual and set-point temperature information and can display temperatures in either Celsius or Fahrenheit.

Digital control makes the bath convenient for routine procedures where established temperature settings must be reproduced from one run to another.

Three Temperature Presets

The Isotemp controller allows users to store three frequently used temperature settings.

This can simplify workflows in laboratories that routinely alternate among established temperatures.

For example, a laboratory performing several common incubation or reagent-warming procedures can save frequently used set points rather than manually entering the temperature for every run.

Presets provide convenience but do not replace appropriate verification when an application requires independently confirmed sample temperatures.

Audible Alarms and Safety Features

The GPD10 incorporates audible alarms for operating conditions including timer completion, low fluid, over-temperature conditions, and safety events.

Low-fluid protection helps reduce the risk of operating the heater without sufficient bath fluid, while adjustable over-temperature protection provides an additional safeguard against unintended heating beyond the desired operating range.

These features are useful for routine laboratory operation but do not replace proper supervision or application-specific safety procedures.

Hinged Polycarbonate Gable Cover

The GPD10 is designed for use with a polycarbonate gable cover.

The hinged cover can be raised to approximately a 90-degree stay-open position or removed completely when necessary.

Using the cover helps reduce heat loss and water evaporation and can improve operating efficiency, particularly during longer procedures or operation at elevated temperatures.

Condensation can accumulate on the inside of the cover during operation and should be considered when opening or removing it.

Diffuser Tray

Fisher supplies the GPD10 with a removable diffuser tray.

The tray helps keep sample containers appropriately positioned above the bottom of the reservoir while supporting circulation of heated water throughout the bath.

Finger openings facilitate removal of the tray for cleaning.

The open-tank design and removable tray simplify access to the stainless steel reservoir when routine cleaning is required.

Sample Incubation

Controlled water baths are commonly used when laboratory samples must remain at a defined temperature for a specified period.

The GPD10 can accommodate compatible tubes, bottles, flasks, and other containers while providing water-mediated heating around the immersed portion of the vessel.

For temperature-sensitive procedures, laboratories should allow sufficient time for the bath and samples to equilibrate and should independently verify sample temperature when required by the method.

Reagent and Buffer Warming

Laboratories frequently need to bring refrigerated reagents, buffers, media, or other solutions to a specified working temperature before use.

The GPD10's 10-liter reservoir allows multiple containers to be warmed simultaneously.

Gentle water-mediated heating can be advantageous when a controlled warming process is preferable to direct heating.

Container compatibility, immersion depth, closure type, and contamination-control requirements should be considered for each application.

Cell Culture and Biotechnology Workflows

Water baths are commonly found in cell-culture and biotechnology laboratories for warming media, buffers, reagents, and other temperature-sensitive materials.

A 37°C water bath is particularly common in biological research because many mammalian-cell and biochemical procedures are performed near physiological temperature.

The GPD10's stability and uniformity make it a practical general-purpose bath for these supporting workflows.

Appropriate contamination-control procedures should be followed, particularly in laboratories where multiple users place containers in the same bath.

Clinical and Biomedical Applications

Fisher identifies the Isotemp general-purpose water-bath family for clinical, pharmaceutical, biomedical, and industrial applications.

The GPD10 can support procedures requiring controlled warming or incubation where its temperature range, stability, uniformity, and chamber dimensions are appropriate.

Suitability for any regulated diagnostic or clinical procedure should be determined according to the laboratory's validated method and applicable requirements.

Pharmaceutical and Quality-Control Applications

Pharmaceutical development and quality-control laboratories frequently require controlled-temperature environments during sample preparation and testing.

The GPD10 can provide a convenient benchtop source of controlled heating for compatible samples, reagents, standards, and laboratory procedures.

Its digital controller and temperature presets can also help operators reproduce routine settings.

Applications requiring documented calibration or qualification should be evaluated according to the laboratory's own quality system.

Water Bath vs. Dry Bath

Water baths and dry block heaters both provide controlled sample heating but use different heat-transfer methods.

The GPD10 surrounds immersed containers with temperature-controlled water, providing broad contact between the heat-transfer medium and the vessel.

Dry baths use heated metal blocks with openings sized for particular tubes or containers.

A water bath can provide greater flexibility in container shape and size, while a dry bath eliminates water maintenance and may offer advantages where open water is undesirable.

Water Bath vs. Heated Circulator

The Fisher GPD10 is a general-purpose water bath rather than a dedicated recirculating bath.

It is designed primarily to maintain samples within its own reservoir.

Laboratory circulators can provide active fluid circulation and, depending on the model, may also pump temperature-controlled fluid to external equipment.

Applications requiring external circulation, very tight temperature control, or cooling below ambient temperature may be better served by a dedicated refrigerated or heated circulator.

Water Bath vs. Shaking Water Bath

The GPD10 provides static temperature-controlled incubation.

A shaking water bath adds mechanical agitation to move samples continuously while maintaining temperature.

Shaking models are useful for applications requiring simultaneous mixing and temperature control, while a general-purpose bath such as the GPD10 is appropriate when controlled heating without agitation is required.

Cleaning and Routine Maintenance

Routine cleaning helps maintain the stainless steel reservoir and reduces the accumulation of biological material, minerals, or other contaminants.

Water should be replaced according to laboratory procedures, and the reservoir and diffuser tray should be cleaned using materials compatible with Fisher's recommendations.

The rounded reservoir corners and removable diffuser tray simplify access during cleaning.

Laboratories using the bath for biological workflows should establish appropriate cleaning and contamination-control procedures for their particular environment.
