When not in use, the check valve ball can stick, preventing the elution of solvents into the
collection vessel. Prior to beginning an extraction, free the Check Valve by using the Check
Valve Tool (PN: 02-0725 for the 1000/3000XL Extractors, or PN: 02-0727 for the 4790

The Speed-Vap IV is a modern evaporation system providing safe and simultaneous unattended evaporation of up to nine pans of evaporating solvent for extractable hydrocarbons such as hexane oil and grease extractions generated using methods such as US EPA 1664, ISO 11349:2010 or Standard Methods 5520. It can also be used to evaporate solvents from extracted soil hydrocarbons and fats from foods.

Microwave assisted organic synthesis has become an important tool to medicinal chemists for rapid organic synthesis. Thousands of research papers have appeared over the last decades on the application of microwave technology in organic synthesis.1 Some of the major advantages include a spectacular decrease in reaction time, improved conversions, clean product formation and wide scope for the development of new reaction conditions.

Peptides are well suited for use as tool compounds to interrogate biological systems and processes due to their chameleonic ability to mimic a potential protein partner within the biological system of interest. Their use in this application continues to grow as the rules governing permeability across the plasma membrane are further elucidated. Unfortunately, a well-defined secondary structure is often required for productive interaction with the other protein partners within the system of interest. ACS, Spring, 2020

The first decision that needs to be made is what the final analysis will be for the analyte. This will have an impact on the sample and cartridge size, as well as the final elution solvent. Gas chromatography offers higher sensitivity than HPLC, while HPLC is better suited for ionisable species and very high molecular weights. If LC-MS is available, minimal sample clean-up may be required.

This poster evaluates two “pass through” solid phase extraction techniques: (protein removal/phospholipid depletion (ISOLUTE PLD+) and dual mode extraction (ISOLUTE HYDRO DME+)) and supported liquid extraction (ISOLUTE SLE+) for a group of about 100 drugs of abuse compounds in whole blood.

For most organic and natural product chemists flash
chromatography is a necessary part of their research. As such, many chemists need quick isolation of at least one desired component from a crude mixture in relatively high yield and purity. This need for speed, purity, and yield pits these desires against each other as you can typically optimize on only two of the three goals.
In this poster, we will describe some techniques that help chemists optimize flash purification and maximize speed, yield, and purity.

Herein we identified an optimized protocol
for removing an Acm protecting group using the Biotage®
Initiator+ Alstra™ and applied the protocol for a fully
automated synthesis with on-resin disulfide bond formation,
simplified with the Branches™ software feature. The results
presented herein provide a route amenable to the synthesis of
other disulfide rich peptides, greatly reducing the effort put
toward synthesizing these complex molecules.

It is well known that traditional liquid-liquid extraction (LLE) provides very clean extracts prior to LC/MS analysis. Supported liquid extraction is analogous to traditional LLE, however, analyte partitioning takes place using an inert support material, rather than two immiscible liquids. This provides excellent extraction efficiencies while alleviating
many of the tedious liquid handling issues associated with LLE.

This application note describes a streamlined procedure for
sample pre-treatment and extraction of a panel of 49 drugs
of abuse from human hair, using Biotage® Lysera for matrix
micropulverization, prior to direct transfer to clean up using
ISOLUTE® SLE supported liquid extraction.
