PerkinElmer PTP-1+1 Peltier Temperature Programmer System

The PerkinElmer PTP-1+1 Peltier Temperature Programmer is a specialized temperature-control accessory designed for UV-Vis spectrophotometric measurements at controlled temperatures. The photographed unit is clearly identified on the front panel as “PTP-1+1 Peltier System”, with separate SAMPLE and REFERENCE temperature channels, confirming the PTP-1+1 configuration.

The PTP-1+1 uses thermoelectric Peltier technology to provide both heating and cooling of spectrophotometer sample and reference cells. PerkinElmer documentation states that the PTP family enables spectrophotometric measurements over a controlled temperature range of approximately 0–100 °C. In the PTP-1+1 configuration, the sample and reference temperatures can be controlled independently through separate channels.

The system is designed to work with compatible PerkinElmer UV-Vis spectrophotometers and associated Peltier cell holders. The PTP-1+1 can be programmed directly through its front panel or interfaced with a PC running TempLab software. Samples can also be agitated using magnetic stirring inside the cuvette, making the system suitable for temperature-dependent spectrophotometric studies.

The PTP-1+1 is particularly useful for experiments where the optical properties of a sample need to be measured while temperature is precisely controlled. Typical applications include protein denaturation, DNA melting studies, thermal transitions, reaction monitoring and temperature-dependent UV-Vis measurements. Published research has used PerkinElmer PTP-1+1 systems with Lambda-series UV-Vis spectrophotometers for variable-temperature spectroscopy.

The photographed unit has substantial cosmetic wear, dirt, staining and discoloration consistent with previous laboratory use. The display areas and front controls are visible, but the photograph does not confirm the operating condition of the Peltier elements, temperature sensors, cell holders or internal electronics.

Applications

The PerkinElmer PTP-1+1 is primarily used for temperature-controlled UV-Vis spectroscopy, allowing researchers to investigate changes in absorbance or other spectrophotometric properties as a function of temperature. The ability to independently control sample and reference channels makes it particularly useful for controlled experimental measurements.

Typical applications include DNA melting and nucleic-acid studies, protein denaturation, biochemical thermal transitions, polymer research, reaction kinetics, temperature-dependent absorbance studies and pharmaceutical/chemical research. Published laboratory facilities also list PTP-1+1 systems with PerkinElmer Lambda UV-Vis spectrometers for temperature-controlled measurements between 0 and 100 °C.

Technical Specifications

PerkinElmer's PTP documentation identifies the PTP-1+1 as a configuration with one sample cell and one reference cell, with independent temperature control for the sample and reference channels. The PTP family provides controlled-temperature spectrophotometric measurements from approximately 0 to 100 °C using Peltier thermoelectric heating and cooling.

PerkinElmer's accessory documentation identifies the PTP-1+1 Research Peltier System as part number L6310012 and describes the research Peltier systems as accessories for applications requiring precise temperature control above, below or at ambient temperature.

Benefits of Refurbished Laboratory Equipment

Purchasing a refurbished PerkinElmer PTP-1+1 Peltier Temperature Programmer can provide laboratories with a cost-effective solution for performing temperature-controlled UV-Vis spectroscopy. The system is especially useful when maintaining older PerkinElmer Lambda-series spectrophotometers that support compatible Peltier accessories.

Refurbished temperature-control accessories can also be valuable for universities, research laboratories, pharmaceutical facilities, biotechnology laboratories and analytical research centers. Proper refurbishment should include testing the Peltier heating/cooling system, temperature sensors, sample/reference channels, displays, controls, communication interface and compatible cell holders.

Additional Information

The photographed unit is clearly identified as a PerkinElmer PTP-1+1 Peltier System. This is a temperature-control accessory rather than a standalone UV-Vis spectrophotometer. It requires a compatible spectrophotometer/cell-holder configuration for spectroscopic measurements.

The exact accessories supplied with the photographed unit cannot be confirmed from the image. Cell holders, temperature probes, magnetic stir bars, cables, cooling-water connections and software may vary depending on the available configuration. The exact electrical rating and compatibility with a specific PerkinElmer spectrophotometer should be verified before purchase.

The equipment has visible cosmetic wear, staining, dirt and discoloration. Functional performance, temperature accuracy, Peltier cooling/heating performance and display operation should be verified during refurbishment/testing.
