Product Group Introduction

 

Silica Bulk

Any type and amount of spherical or irregular silica gel can be delivered in bulk format, in different grades. Not only the often used flash silica 40-63um but also any type of silica-based solid phase extraction material as well as dedicated functionalized silica for synthesis or as scavenger is available in bulk.  

 

Silica Specialties

Without bothering about packing yourself, ready to use pre-packed columns with any type of silica as described in de Silica Bulk section including solid phase extraction material are covered. Our Silica Specialties include several disks and depending on your needs, open or closed columns and of course TLC plates - both analytical and preparative. The columns can be coupled to loading adapters if needed.

About Irregular and Spherical Shaped Silica

The quality of a silica gel is extremely important when you are using it for chromatography purposes, particularly when dealing with difficult separations of valuable compounds. You need to be confident about your recoveries. In chromatography, there are at least three physical properties that will influence your separation and that you need to consider when choosing your silica gel:

  • Particle shape (irregular or spherical )
  • Particle size distribution (tight or large)
  • Pore diameter (surface area)

These characteristics will directly influence crucial parameters involved in a successful chromatography:

  • Resolution (efficiency of separation & final purity)
  • Retention (which allows separation)
  • Capacity (maximal sample quantity and final recovery/yield)
  • Back-pressure (speed and pumps related issues)


Silica: Spherical

Due to narrower particle size distribution, applying spherical silica gels results in high-performance separations. The particle sizes 1.8-5um find their application on analytical scale chromatography, the 10-16um gels are used in preparative chromatography. Available in 60 up to 300A pore sizes. Besides the monodispersed spherical silica a dedicated preparative range of spherical silica is available.  


Silica: Functionalized

SiliCycle is the leader in the development of functionalized silica gels, gathered under the name SiliaBond, for use in organic synthesis. The backbone of all SiliaBond products is SiliCycle SiliaFlash® F60 which provides superior performance for all types of applications due to the narrow particle size distribution and high purity. All the products in this section are made of standard flash silica gel, namely 40-63µm, 60A. We are able to provide all functionalized products on any silica of this catalog (SiliaFlash, IMPAQ™, SiliaSphere™ and SiliaSphere™ PC) in any format (SiliaPrep™ SPE and SiliaSep™, SiliaSep, etc.) on a custom basis. 


Silica: TLC Plates

For over 18 years, SiliCycle has been offering a wide selection of TLC plates in various sizes (plate, thickness), backings (Glass, Aluminum, Plastic) and chemistries (CN, C18, NH2, 10% Silver Nitrate) to provide best separation experience for both qualitative and quantitative analysis. SiliaPlate represents an efficient and economical alternative to other TLC plate manufacturers while demonstrating high separation efficiency and low background noise, due to the narrow particle size distribution silica gel used for manufacturing.
