SPE Accessories
VacMaster Manifolds
VacMaster Sample Processing Manifolds are used to process up to ten (VacMaster-10) or twenty (VacMaster-20) samples simultaneously.
Designed to meet the most demanding criteria for safety, extract purity, flexibility and ease-of-use, the VacMaster manifolds provide productivity enhancements in many applications.
Both VacMaster-10 and -20 manifolds are supplied complete with thick walled glass tank, PTFE lid, fine vacuum control and vacuum safety valve, inert polyethylene collection tube rack, port sealing plugs and replaceable stainless steel needles that are compatible with all industry standard Luer tipped SPE columns.
Features and Benefits
- Parallel sample processing for SPE and filtration applications
- Robust, inert system made of glass, PTFE and polyethylene, avoiding sample contamination
- Optional PTFE stopcock and stopcock/needles for additional flow control and purity
- Clear view of sample processing operation with thick walled glass tank
- Collection tube rack with easy to lift carrying handle for safe transfer of samples
- Vacuum safety valve fitted as standard to ensure safe sample processing
- Range of productivity enhancing accessories
Vacmaster-96 Manifold
The VacMaster-96 Sample Processing Manifold is a versatile system ideal for all 96-well SPE, protein precipitation, supported liquid extraction and filtration applications.
The small footprint and lightweight construction make it suitable for manual processing or use with automated liquid handling systems. The manifold is designed for full compatibility with all commercially available extraction, filtration and collection plates.
A simple system based on inserts and spacers optimizes extraction and collection plate positioning, eliminating well-to-well contamination and sample loss.
The spacer required for compatibility with the modular Array format plate is supplied as standard with the VacMaster-96 manifold.
Features and Benefits
- Vacuum processing for all 96-well sample preparation applications
- Compatible with fixed well and modular Array plates
- Solvent resistant construction for robust, reliable operation
- Separate vacuum control options prevent contamination
- Sloping internal base eliminates requirement for disposable reservoir trays
- Easy to clean unit for bioanalytical applications
Vacuum Control Units (VCU-1 & VCU-2)
VacMaster VCU-1 : an independent polypropylene unit with vacuum gauge, on/off switch and fine controls. Use with a laboratory vacuum source.
VacMaster VCU-2 : an independent polypropylene unit with all the controls of the VCU-1, plus an integral vacuum generator. The unit converts laboratory compressed air into a vacuum source, eliminating the need for a vacuum pump.
VacMaster Trap Kit
This solvent trap should be installed between the outlet of the sample processing manifold and the vacuum source, trapping all liquids aspirated through the manifold. The trap is compatible with VacMaster-10, -20 and -96 Sample Processing Manifolds.
The kit consists of a 1L polypropylene vacuum flask, polyethylene stopper with connectors, sealing gasket and 1.5 m vacuum tubing.
Features and Benefits
- Collect waste solvents and samples, cleanly and efficiently
- Prevent contamination of vacuum control units, removing spray of aspirated liquid
- Easy to clean components, reducing preparation time
VacMaster Drying Adapter
Prior to elution of analytes from an SPE column with water immiscible solvents, it is often necessary to dry the sorbent bed to achieve optimum and reproducible recoveries. The VacMaster Drying Adapter directs a stream of gas efficiently through the column, significantly reducing drying times compared to vacuum aspirated air flow.
Features and Benefits
- Fast, efficient SPE column drying
- Use with any suitable gas (e.g. nitrogen, air)
- Options for VacMaster-10 and VacMaster-20 Sample Processing Manifolds
VacMaster Large Volume Extraction (LVE) kit
The VacMaster Large Volume Extraction (LVE) Kit is designed to speed up processing of large volume samples using VacMaster Sample Processing Manifolds.
PTFE tubing is placed into the sample container, and is secured with a tubing clip. The other end of the tubing is attached to the ISOLUTE SPE column using a column adaptor.
When vacuum is applied, the sample is drawn through the inert tubing path, and through the SPE column. Each kit contains PTFE tubing (10 x 1 m) with numbered tags, tubing clips (10) and column adaptors (10).
Features and Benefits
- Unattended loading of large volume samples
- PTFE components prevent sample contamination
Sample Concentrator System (SPE Dry 96)
- (SPE DRY 96 DUAL)
Solvent evaporation prior to analysis is a time consuming part of analytical sample preparation, and with the increasing use of high throughput formats and short analytical cycle times, it can become a bottleneck.
The SPE Dry 96 and SPE Dry 96 Dual Sample Concentrator Systems offer fast, efficient solvent evaporation from 96-well plate formats. Both systems deliver heated gas from above and below the plate, ensuring rapid, reproducible evaporation for a range of commonly used solvents.
The systems are ideal for solvent evaporation following SPE, supported liquid extraction (SLE) and protein precipitation applications. SPE Dry 96 and SPE Dry 96 Dual systems are supplied with removable stainless steel needles.
For applications that use aggressive solvents and buffers, PTFE coated needles are available.
Features and Benefits
- Fast, efficient solvent evaporation from 96-well plates
- Rapid equilibration and precise temperature control
- Compact size/small footprint
- Single and dual plate options
- Also compatible with 48-well and 384-well formats
- PTFE coated needle options for added solvent resistance
