Agilent 1290 Autosampler Thermostat (G1330B)

What you are buying

A refurbished Agilent 1290 Infinity G1330B Autosampler Thermostat, with warranty coverage. It holds samples at a set temperature in the autosampler tray, protecting temperature-sensitive samples before injection.

Every unit we sell moves through the GenTech Certified process. Solution Scientists disassemble and inspect each module, replace all consumables and degraded wear components, then tune and calibrate the instrument and verify performance against OEM and published benchmarks using known reference chemicals. The instrument ships with its verification report. A certified-refurbished system gives you that performance without the capital cost or the lead time of a new purchase.

What Agilent says about this platform

Agilent built the G1330B around the same Peltier-controlled heat exchangers as the G1330A, with a settable temperature range of 4 to 40 degrees Celsius in 1-degree increments. Temperature accuracy holds to between -1 and +4 degrees Celsius at a 4-degree setpoint when ambient temperature stays under 25 degrees Celsius and humidity under 50 percent, widening to +5 degrees Celsius above that ambient threshold. Agilent highlights this module for its advanced solid-state Peltier cooling and heating architecture, which sits beneath the main autosampler to regulate the sample compartment without the need for noisy or maintenance-heavy compressors. By continuously circulating dehumidified, temperature-controlled air across the sample vials or microplates, the G1330B completely eliminates condensation and temperature gradients. The thermostat pairs with the G1389A, G1367A, or G2260A autosampler module over a control cable, with each module keeping its own power supply. It works with other 1200 or 1290 Infinity Series modules, or with other LC systems that have adequate remote control inputs and outputs, controlled from the Agilent Instant Pilot or from Agilent’s own LC control software. The thermostatted sample tray holds 100 1.8-milliliter vials, or two well plates plus 10 1.8-milliliter vials. The unit operates up to 2000 meters altitude and tolerates humidity under 95 percent at 40 degrees Celsius without condensing. It measures 13.5 by 17 by 5.5 inches and weighs 20.7 kilograms.

What this module does

Rather than a standalone sample tray, the Agilent G1330B is a dedicated external thermal regulation module that docks directly with an analytical autosampler stack (such as the G1329B, G1367E, or G4226A). Positioned immediately below the host autosampler compartment, its primary job is to cool or heat the sample environment to protect volatile or unstable compounds. This process executes several critical system-wide functions:

• Prevents Analyte Degradation: It cools the sample deck down to 4 °C, effectively slowing down enzymatic breakdown or thermal degradation of delicate biological samples waiting in the queue.
• Eliminates Condensation Build-Up: It features a built-in condensation handling channel that routes moisture away from the electronics, ensuring a dry, safe environment inside the sample chamber.
• Minimizes Volatilization Losses: It regulates ambient conditions to prevent the evaporation of low-boiling-point solvents, preserving exact sample concentrations across extended runtime sequences.
• Maintains Thermal Uniformity: It leverages a high-capacity internal fan assembly to evenly distribute conditioned air across all vials or microtiter well-plates, eliminating localized warm spots.

Connects to a G1389A, G1367A, or G2260A autosampler module over a control cable, each keeping its own power supply.
