• Easy-open packets eliminate the need for a second empty tube for salt transfer.
• Convenient slim packets fit perfectly into tubes to prevent spills.
• Ready-to-use tubes, no glassware required.
• Pre-weighed, ultra-pure extraction salts.
• Ideal for original unbuffered, AOAC (2007.01), and European (EN 15662) QuEChERS methods.

Fast, Simple Sample Prep for Multiresidue Pesticide Analysis

• Packaged in foil subpacks of 10 for enhanced protection and storage stability.
• Ready-to-use tubes, no glassware required.
• Pre-weighed, ultra-pure sorbents.
• Support original unbuffered, AOAC (2007.01), European (EN 15662), and mini-multiresidue QuEChERS methods.

• Adjustment knob offers 56 output volume settings from 2.5 mL to 30 mL per stroke (0.5 mL increments)—ideal for QuEChERS methods!
• Base features 30 mm threads and includes five adaptors (28 mm, 32 mm, 36 mm, 40 mm, and 45 mm).
• Individually calibrated in accordance with ISO 8655 standards (certificate included) and can also be recalibrated by the user.
• PTFE, glass, and polypropylene construction for excellent chemical compatibility and 100% autoclavability.
• Integral safety discharge reduces risk of accidental dispensing, and nozzle cap prevents dripping.
• Easy to disassemble for cleaning and servicing.

• Program 10 custom cycles for time, braking, and speed or g-force (up to 4500 rpm or 3450 xg).
• QuEChERS-specific presets for AOAC and EN methods make consistent operation quick and simple.
• Convenient lid lighting indicates at a glance if unit is ready, running, or done.
• Control panel can be temporarily locked on one cycle for error-free reproducibility.
• Cool-Flow design prevents samples from overheating by maintaining unit at room temperature.
• Tube holders are carbon fiber for high strength, durability, and years of trouble-free use.
• Clear lid permits safe observation of samples and optical calibration of speed.

• Available for 2 mL, 15 mL, and 50 mL tubes.
• Alphanumerical grid reference on top tier for easy identification of samples.
• Easy to assemble; simply fold and snap together securely.

• Designed for use in all QuEChERS methods for pesticides in fruits and vegetables, including the original unbuffered method, AOAC 2007.01, and EN15662.
• Ideal for initial method evaluations and ongoing method performance validations.
• Optimized blend of chemically compatible analytes for maximum stability and shelf life.
• Precise formulation improves data quality and operational efficiency; spend more time running samples and less time sourcing and preparing standards.
• Quantitatively analyzed to confirm the composition and stability of each mixture.

• Kit contains organochlorine, organonitrogen, organophosphorus, and carbamate pesticides commonly used on fruits and vegetables.
• Volatile, polar, active, base-sensitive, and nonvolatile compounds are included to allow comprehensive evaluation of QuEChERS extraction and cleanup efficiencies, and optimization of GC and LC instrumental conditions.
• Ideal for initial method evaluations and ongoing method performance validations.
• Analytes are divided into three ampuls based on compatibility for maximum stability and shelf life.*
• Precise formulations improve data quality and operational efficiency; spend more time running samples and less time sourcing and preparing standards.
• Quantitatively analyzed to confirm the composition and stability of each mixture.

*When combining compounds with different functionalities, chemical stability can be an issue. The analytes in this kit are separated into three mixes to ensure maximum long-term storage stability. For analysis, a fresh working standard should be prepared by combining the three kit mixes in a 1:1:1 ratio to prepare a 100 µg/mL working standard solution. Once blended, Restek does not recommend storing working standards or subsequent dilutions for future use.

Contains 1 mL each of these mixtures.
