Temperature Effects Crystallization Size and Shape
Supersaturation Control Optimizes Crystal Size and Shape

Crystallization kinetics are characterized in terms of two dominant processes, nucleation kinetics and growth kinetics, occurring during crystallization from solution. Nucleation kinetics describe the rate of formation of a stable nuclei. Growth kinetics define the rate at which a stable nuclei grows to a macroscopic crystal. Advanced techniques offer temperature control to modify supersaturation and crystal size and shape.

Continuous Crystallization Processes
Real-Time Monitoring for Modeling and Control

Continuous crystallization is made possible by advances in process modeling and crystallizer design, which leverage the ability to control crystal size distribution in real time by directly monitoring the crystal population.

Anti-Solvent Addition on Supersaturation
How Solvent Addition Can Control Crystal Size and Count

In an antisolvent crystallization, the solvent addition rate, addition location and mixing impact local supersaturation in a vessel or pipeline. Scientists and engineers modify crystal size and count by adjusting antisolvent addition protocols and the level of supersaturation.

Batch Crystallization Optimization and Process Design
Generate Supersaturation and Determine Final Crystal Product

A well-designed batch crystallization process is one that can be scaled successfully to production scale - giving the desired crystal size distribution, yield, form and purity. Batch crystallization optimization requires maintaining adequate control of the crystallizer temperature (or solvent composition).

Metastable Zone Width (mzw) Determination
The Building Blocks of Crystallization

Solubility curves are commonly used to illustrate the relationship between solubility, temperature, and solvent type. By plotting temperature vs. solubility, scientists can create the framework needed to develop the desired crystallization process. Once an appropriate solvent is chosen, the solubility curve becomes a critical tool for the development of an effective crystallization process.

Lactose Crystallization
Recover Lactose with High Yield and Scalable Process

Lactose crystallization is an industrial practice to separate lactose from whey solutions via controlled crystallization.

Ustvarite strukturirane, urejene mreže za kompleksne makromolekule

Kristalizacija beljakovin je dejanje in metoda ustvarjanja strukturiranih, urejenih mrež za pogosto kompleksne makromolekule.

Protokol za kristalizacijo
Načrtujte in optimizirajte protokol sejanja za izboljšano skladnost serij

Sejanje je eden najbolj kritičnih korakov pri optimizaciji kristalizacijskega vedenja. Pri oblikovanju strategije sejanja je treba upoštevati parametre, kot so velikost semena, obremenitev semena (masa) in temperatura dodajanja semena. Ti parametri so na splošno optimizirani na podlagi kinetike procesa in želenih končnih lastnosti delcev in morajo ostati dosledni med povečanjem in prenosom tehnologije.

Oiling Out in Crystallization
Detect and Prevent Oiling Out (Liquid-Liquid Phase Separation)

Liquid-Liquid phase separation, or oiling out, is an often difficult to detect particle mechanism that can occur during crystallization processes.

Measure Crystal Size Distribution
Improve Crystallization with Inline Particle Size, Shape, and Count Measurement

In-process probe-based technologies are applied to track particle size and shape changes at full concentration with no dilution or extraction necessary. By tracking the rate and degree of change to particles and crystals in real time, the correct process parameters for crystallization performance can be optimized.

Temperaturni učinki Velikost in oblika kristalizacije
Povečanje vznemirjenja, doziranja in kristalizacije

Spreminjanje lestvice ali pogojev mešanja v kristalizatorju lahko neposredno vpliva na kinetiko procesa kristalizacije in končno velikost kristala. Učinke prenosa toplote in snovi je treba upoštevati pri hladilnih sistemih in sistemih proti topli, kjer lahko temperaturni ali koncentracijski gradienti povzročijo nehomogenost prevladujoče stopnje prenasičenosti.

Crystal Polymorphism
Understand Polymorphism and the Impact of Process Parameters

Crystal polymorphism describes the ability of one chemical compound to crystallize in multiple unit cell configurations, which often show different physical properties.

Presežek nasičenosti
Pogon za kristalizacijo

Presežek nasičenosti nastane, ko raztopina vsebuje več raztopljene snovi, kot bi bilo termodinamično mogoče glede na pogoje sistema. Presežek nasičenosti velja za glavni dejavnik kristalizacije.

Recrystallization
Optimization of Crystal Properties and Process Performance

Recrystallization is a technique used to purify solid compounds by dissolving them in a hot solvent and allowing the solution to cool. During this process, the compound forms pure crystals as the solvent cools, while impurities are excluded. The crystals are then collected, washed, and dried, resulting in a purified solid product. Recrystallization is an essential method for achieving high levels of purity in solid compounds.
