VWR 1275PC waterbath

VWR 1275PC 100L General Purpose Water Bath – Used and Refurbished

The VWR 1275PC is a large-capacity, microprocessor-controlled laboratory water bath designed for applications requiring substantially more working space than a conventional benchtop bath. With a 100-liter capacity and an interior chamber measuring approximately 18"W × 36"D × 9"H, the 1275PC provides room for large vessels, multiple sample containers, racks, bottles, and high-throughput temperature-controlled laboratory workflows.

Designed for professional, industrial, research, and educational laboratory use, the VWR 1275PC provides an operating temperature range from approximately 5°C above ambient to 70°C. The microprocessor controller provides precise electronic temperature regulation, while the large stainless steel chamber allows laboratories to process substantially larger sample loads than would be practical in a typical 5-, 10-, or 20-liter water bath.

VWR specifies temperature uniformity of ±0.2°C at 37°C and temperature sensitivity of ±0.07°C for the 1275PC. These performance characteristics, combined with the unusually large chamber, make the bath particularly useful for high-volume sample incubation, reagent and media warming, temperature equilibration, large-container heating, biotechnology workflows, pharmaceutical research, industrial testing, and other procedures requiring a large temperature-controlled water reservoir.

This VWR 1275PC water bath is used and refurbished by American Instrument Exchange. AIE technicians test used water baths before shipment to verify heating and temperature operation. The bath is thoroughly cleaned and includes a 90-day warranty.

Overview

Most laboratory water baths are designed for relatively small sample loads. The VWR 1275PC takes a different approach.

With a nominal 100-liter capacity, this model provides approximately five times the bath volume of a typical 20-liter laboratory water bath. The broad 18 × 36-inch working area provides substantial room for arranging samples, racks, bottles, vessels, or other compatible laboratory containers.

This makes the 1275PC particularly useful when a laboratory needs to maintain numerous samples at the same temperature or accommodate containers that simply will not fit inside a conventional benchtop bath.

Microprocessor temperature control allows the bath to maintain a selected operating temperature while water provides efficient heat transfer around immersed containers.

Key Specifications

Common Applications

The VWR 1275PC can support large-batch sample incubation, reagent warming, media warming, buffer conditioning, temperature equilibration, microbiology procedures, biotechnology workflows, pharmaceutical research, industrial testing, quality-control procedures, and other applications requiring controlled heating of multiple samples or larger containers.

Its large chamber is particularly advantageous when several vessels must be held at the same temperature simultaneously.

The bath can also provide a common temperature-controlled environment for applications where processing samples individually in multiple smaller water baths would be inconvenient or inefficient.

Ideal Laboratory Types

The VWR 1275PC is well suited to biotechnology companies, pharmaceutical laboratories, industrial research facilities, manufacturing quality-control laboratories, university research centers, biomedical laboratories, microbiology facilities, food and beverage laboratories, environmental laboratories, contract research organizations, and other facilities with high-volume temperature-control requirements.

It may be especially valuable in laboratories where smaller water baths have insufficient working area for routine sample loads.

Large 100-Liter Capacity

The defining feature of the VWR 1275PC is its 100-liter chamber capacity.

This is substantially larger than the capacity of most general-purpose benchtop laboratory water baths.

The large reservoir allows users to arrange numerous sample containers within a common temperature-controlled environment and can accommodate vessels that would not fit into conventional compact baths.

Actual usable capacity depends on sample-container dimensions, required immersion depth, water level, racks, and the amount of clearance required for proper heat distribution.

18 × 36-Inch Working Area

The interior chamber measures approximately 18 inches wide × 36 inches deep × 9 inches high.

The 36-inch dimension provides an unusually large working area for a laboratory water bath.

This broad footprint can be useful when positioning multiple bottles, sample racks, containers, or large vessels side by side.

For high-throughput workflows, the available surface area may be just as important as the nominal 100-liter fluid capacity.

Ambient +5°C to 70°C Temperature Range

The VWR 1275PC is designed for operation from approximately 5°C above ambient temperature to 70°C.

This range covers many common laboratory warming and incubation temperatures, including applications near physiological temperature as well as higher-temperature procedures.

Because the 1275PC is a heated bath without active refrigeration, it cannot independently maintain temperatures near or below room temperature.

Applications requiring sub-ambient operation should use an appropriate refrigerated bath or circulator.

Temperature Uniformity

VWR specifies temperature uniformity of ±0.2°C at 37°C for the 1275PC.

Uniformity describes temperature variation at different locations within the bath once the system has reached equilibrium.

Maintaining uniform temperature conditions is especially important in a large 100-liter bath because samples may be positioned considerable distances apart within the chamber.

Actual performance can be influenced by sample loading, container placement, water level, operating temperature, ambient laboratory conditions, and equilibration time.

Temperature Sensitivity

The original VWR specifications list temperature sensitivity of ±0.07°C for the 1275PC.

This specification reflects the ability of the controller and heating system to respond to and regulate temperature changes under specified operating conditions.

For temperature-sensitive procedures, laboratories should allow the bath to reach full equilibrium before samples are introduced.

Applications requiring documented or independently verified temperature performance should use an appropriate calibrated reference thermometer or temperature probe according to laboratory procedures.

Microprocessor Temperature Control

The 1275PC uses microprocessor-based temperature control rather than the simpler analog thermostatic controls found on many older water baths.

Electronic regulation provides convenient temperature setting and monitoring for routine laboratory workflows.

Microprocessor control can also help operators reproduce established operating conditions between procedures.

For laboratories running repetitive incubation or warming protocols, consistent equipment setup can contribute to more standardized workflows.

High-Throughput Sample Processing

The large working area makes the 1275PC particularly attractive for laboratories processing many samples simultaneously.

Instead of dividing a batch among several smaller baths, users may be able to place multiple racks or vessels within the same temperature-controlled reservoir.

This can simplify workflow and provide a common thermal environment for samples processed together.

The appropriate loading arrangement depends on the laboratory method and should allow adequate water contact around containers.

Large Vessel Heating

Some laboratory containers are simply too large for conventional benchtop water baths.

The 18 × 36 × 9-inch chamber gives the 1275PC considerably more flexibility for accommodating larger vessels.

Large bottles, containers, racks, and other compatible laboratory vessels may be partially immersed for controlled warming when their dimensions and application requirements are appropriate.

Users should ensure that containers are stable and suitable for immersion at the intended operating temperature.

Reagent and Buffer Warming

Large-volume laboratories may need to warm numerous bottles of buffers, media, reagents, or process solutions simultaneously.

A 100-liter water bath can provide significantly more capacity for these workflows than a conventional small bath.

Water-mediated heating provides gentle thermal transfer around the immersed portion of each container.

Actual warming time depends on container volume, starting temperature, bath temperature, container material, immersion depth, and sample loading.

Media Warming

Biotechnology and biomedical laboratories frequently warm culture media and other solutions before use.

For facilities processing many bottles at once, a large bath such as the 1275PC can provide significantly more working area than a standard 10-liter unit.

The 37°C operating point commonly used in biological laboratories falls well within the bath's operating range and is also the temperature at which VWR specifies ±0.2°C uniformity.

Appropriate contamination-control procedures should be established when a water bath is used in support of cell-culture or microbiology workflows.

Biotechnology Applications

Biotechnology facilities can use large-capacity water baths for media and buffer preparation, reagent warming, sample incubation, temperature equilibration, thawing procedures, and other temperature-controlled workflows.

The 1275PC is particularly useful where sample volume or throughput exceeds the practical capacity of smaller benchtop baths.

Its large chamber can also reduce the need to maintain several independent baths at the same temperature.

Pharmaceutical Laboratory Applications

Pharmaceutical research, development, and quality-control laboratories may require temperature-controlled water baths for sample preparation, reagent conditioning, incubation, dissolution-related support procedures, and other laboratory workflows.

The VWR 1275PC provides substantial capacity for procedures involving numerous samples.

Suitability for validated or regulated methods should be established according to the laboratory's own SOPs, calibration program, and quality requirements.

Industrial and Quality-Control Applications

The 1275PC was designed for professional and industrial as well as educational laboratory use.

Industrial laboratories may use large water baths for product testing, materials evaluation, component conditioning, quality-control procedures, formulation work, and temperature equilibration.

The large chamber provides flexibility for processing multiple samples or relatively large test items simultaneously.

Only compatible, nonflammable materials appropriate for water-bath heating should be used.

Water Bath vs. Heated Circulator

The VWR 1275PC is a general-purpose water bath designed primarily to maintain samples within its own reservoir.

A dedicated heated circulator actively circulates temperature-controlled fluid and may provide external pump connections for conditioning another vessel or instrument.

Applications requiring external circulation, exceptionally tight temperature control, or specialized fluid dynamics may be better suited to a laboratory circulator.

The 1275PC's principal advantage is its exceptionally large internal working area.

Water Bath vs. Shaking Water Bath

The 1275PC provides temperature control without mechanical sample agitation.

A shaking water bath combines temperature control with an oscillating platform that continuously agitates sample containers.

Applications requiring simultaneous temperature control and shaking should use an appropriate shaking bath.

For large-scale static incubation, warming, or equilibration, the 1275PC provides substantially more usable chamber space than many shaking models.

Water Bath vs. Laboratory Incubator

A water bath transfers heat through water in direct contact with the immersed portion of a sample container, while a laboratory incubator controls the surrounding air temperature.

Water generally provides more efficient heat transfer than air, which can allow samples to reach the desired temperature effectively.

Incubators, however, can accommodate containers and materials that should not be immersed.

The appropriate system depends on the sample type, required temperature, container, workflow, and analytical method.

Installation Requirements

Because of its size, the VWR 1275PC requires more installation planning than a small benchtop water bath.

The unit measures approximately 51 inches wide × 26.5 inches deep × 24.5 inches high and has a net weight of approximately 78 pounds before water or samples are added.

Once filled with approximately 100 liters of water, the complete installation can weigh several hundred pounds.

The bath should therefore be installed on a stable surface capable of supporting the filled operating weight.

220–240 V Electrical Requirement

The original VWR manual specifies 220–240 V, 9 A, 50/60 Hz electrical service for the 1275PC.

This is an important distinction from many smaller laboratory water baths that operate from a conventional 120 V laboratory receptacle.

Customers should confirm that the intended installation location has appropriate electrical service before purchasing the bath.

The individual unit's nameplate should always be checked before electrical connection.

Cleaning and Routine Maintenance

The large reservoir should be cleaned routinely to prevent accumulation of mineral deposits, biological growth, and other contamination.

Water should be replaced according to laboratory procedures and the requirements of the application.

Because a 100-liter bath contains a substantial amount of water, laboratories should consider filling, draining, and cleaning logistics when selecting the installation location.

Only cleaning agents and bath additives compatible with the system should be used.
