a. ROT-X-TRACT-L

The ROT-X-TRACT-L rotary liquid-liquid extractor allows for up to 8 liquid-liquid extractions to be performed at once. The instrument was designed to simplify extractions using a traditional liquid-liquid extraction apparatus or the Hershberg-Wolfe extraction apparatus.

Traditional configurations of these extractors employ 250 ml boiling flasks, an Allihns condenser, and 1-liter extractor bodies. These highly efficient instruments provide continuous solvent extraction and use a large diameter return tube to minimize any chance of clogging.

The extractor hardware can also accommodate Hershberg-Wolfe (H-W) glassware and frits for more accurate extraction of samples. The H-W extractor body assembly increases the amount of time the solvent is in contact with the sample promoting a more accurate extraction of analytes. Both the traditional and H-W extractors come with remote power and water control box. The control box provides a safety feature for unattended operation, automatically shutting off heat and water to the extractor when water flow from the return line diminishes.

All extractors are engineered using a circular design for easy insertion and retrieval of samples. Please contact us for any specific questions about these instruments.

Advantages:

• Conserves valuable bench space: all samples are arranged in a circle
• Easy sample access: the instrument rotates allowing all samples to be accessed from the front
• Fewer connections: One water supply line in, one drain line out

Standard Features:

• Stainless steel construction
• Stepped bath rim and cover disk seal steam chamber
• Each condenser water line attached to the centrally located water manifold
• Water control box
• Flowmeter
• Laboratory grade materials stand up to organic solvents

b. ROT-X-TRACT-LC

The ROT-X-TRACT-LC is designed to accommodate up to eight (8) Corning Accelerated One-Step apparatuses. The Corning Accelerated One-Step extraction apparatus combines continuous liquid-liquid extraction and concentration into one step. A cold-finger condenser is used to reduce overall height to accommodate traditional laboratory hood specifications; however, Allihn condensers can be substituted per customer request.

The hydrophobic membrane allows the organic solvent to circulate through the 1 liter sample bottle continuously until the extraction is complete. By incorporating a stop-cock assembly and 3-ball Snyder column, the Corning One-Step extractor can both extract desired analytes as well as evaporate solvent from the end by-product within the same cycle.

The Corning One-Step extractor comes with an electronic side control box which enables the operator to program specific bath temperatures and time cycles to stay in compliance with the designated methodologies.

Advantages:

• Multiple simultaneous extractions: extract and concentrate up to eight samples simultaneously
• Precise controls: digital timer and heat controls
• Fewer connections: one water supply line in, one drain line out
• Organomation vacuum insulated concentrator tubes keep delicate samples safe
• The water bath is gentler than jacketed concentration tubes in the traditional set-up
Standard Features:
• Stainless steel construction
• Stepped bath rim and cover disk seal steam chamber
• Each condenser water line attached to the centrally located water manifold
• Side control box
• Water flow meter
• Laboratory grade materials stand up to organic solvents

c. ROT-X-TRACT-S

Soxhlet extraction is ideal for extracting soluble analytes from a solid sample into an organic solvent. Unlike traditional wire or sand baths which are used to heat receiving flasks, the ROT-X-TRACT-S uses a water steam bath which provides gentle even heat to delicate samples.

The ROT-X-TRACT-S rotary Soxhlet extractor can accommodate up to 8 or 10 Soxhlet extractors. The bath cover disc holes can accommodate round sample flasks from 125 ml-1 L. A wide range of sample sizes and quantities make this instrument ideal for Soxhlet extraction of samples in any lab.

Advantages:

• Conserves valuable bench space: all samples are arranged in a circle
• Easy sample access: the instrument rotates allowing all samples to be accessed from the front
• Fewer connections: one water supply line in, one drain line out
Standard Features:
• Stainless steel construction
• Stepped bath rim and cover disk seal steam chamber
• Each condenser water line attached to the centrally located water manifold
• Laboratory grade materials stand up to organic solvents
