Model 3300 ELSD is designed for use with High Performance Liquid Chromatography (HPLC) systems to analyze any sample compound that has sufficiently lower volatility than the mobile phase. Some of its possible application areas include carbohydrates, pharmaceuticals, lipids, triglycerides, underivatized fatty and amino acids, polymers, surfactants, nutraceuticals, and combinatorial libraries. Evaporative light scattering detection eliminates common problems associated with other HPLC detectors. Refractive Index (RI) detectors can be complicated by solvent front interferences, baseline instability, and gradient incompatibility. RI detectors can also have a less sensitive response than ELSD. Low-wavelength UV can suffer baseline drift with steep gradients and also requires that the analyte contains a chromophore. ELSD does not have these limitations. It can achieve stable baselines with multisolvent gradients for improved resolution and faster separations. Also, since ELSD response does not depend on the sample’s optical characteristics, the sample does not require a chromophore or fluorophore for detection.

The G1512A Autosampler Controller for a 5890 or 6890 GC.  This unit transfers the communication between the Autosampler and the GC.

Specifically designed to minimize operator fatigue, the Portable Pipet-Aid XP is smaller and lightweight. It accepts most pipettes from 1 to 100 mL.

Each pipette filler and pipet dispenser button has three speeds, (F) Fast, (M) Medium, (S) Slow. The medium speed is suitable for most routine techniques. Fast speed can deliver up to 50 mL in 5 seconds and can be used for rapid filling of large pipets or breaking up cell clumps. Slow speed is ideal when using small pipettes or when more precise delivery is required. A gravity drain model is available which substitutes a gravity drain (G) function for the fast (F) mode on the dispense button.

The XP is powered by a 9 volt (Ni-MH) rechargeable battery.

A Tissue Culture Nosepiece, which features a unique filter element, will cease to allow air to pass in either direction if it becomes wet, alerting the user to possible contamination of the rubber insert.

Features:

• The lightweight, compact Portable Pipet-Aid®
• Three-speed settings provide more precise control for use in the pipet filler mode and the pipette dispenser mode
• Easy access battery replacement
• EZ Grip nosepiece with double membrane filter
• Removable stand
