Character
Yingtai pilot-type freeze dryer completely simulates the technical requirements of the industrial freeze dryer,with a compact and reasonable design,a large redundancy range,and conforms to GMP and FDA standards.The ice condensation capacity is 4~18kg,and the WRL controller and liquid temperature control shelf are adopted,so that the process of pre-freezing and freeze-drying can be precisely controlled on the main machine,and the process results are quite comparable with the production machine.In addition to supporting the eutectic point test system,pressure rise and pressure comparison method to determine the freeze-drying end point and freeze-drying curve recording software,hallan pilot-type freeze dryer can also be equipped with engineering WRL control software to directly Graphical computer control the freeze-drying process.It can be configured with H202 sterilization and high-pressure steam sterilization orintegrated glove box system, which can be used for clean room operation through the wall.The cold trap and freeze-drying chamber are all designed with 316L stainless steel to ensure the cleanliness of the chamber and good ultimate vacuum and vacuum leakage rate to the greatest extent.
Refrigeration Series
● Dual compressors,Secop special compressors,air cooling (water cooling system is optional)
Silicone oil conducts heat,with uniform temperature and accuracy up to 0.1°C.Silicone oil has a wide temperature range,up to-100°C~+600°C.
● Shelf refrigeration system and cold trap refrigeration system are completely independent,without any switching,refrigeration temperature is lower and more stable.
Vacuum series
● Vacuum pump:German Pfeiffer anti-corrosion,anti-oil return function vacuum pump.(Vacuum pump can be selected according to user needs)
● Pumping rate:9m³/h~62m³/h,multiple specifications are optional,the ultimate vacuum can reach 2×10-3mbar,and the oil mist filter is standard.
● The vacuum pipelines are all high-vacuum stainless steel vacuum tubes, which can effectively prevent vacuum leakage and corrosion.
● The double anti-oil return device completely eliminates the damage and
equipment and samples.
● Automatic backfill air device,the system has a built-in High efficiency particulate air(HEPA)filter to ensure the complete cleanliness of backfill air.
● The vacuum stabilization system can stabilize the vacuum degree of the freeze-drying process through the micro-pass vacuum control valve to ensure that the samples will not be affected by excessive fluctuations in the vacuum degree.
● Condensed liquid collection and discharge system,automatically completes the collection and discharge of condensed liquid after freeze-drying.
Control SystemCharacteristic
● Control:Automatic/Manual
● Can store at least 100 independent freeze-drying programs,each program contains 32 program segments (Can be
customized according to user needs),each program segment corresponds to a processing stage (pre-freezing,main
drying,post-drying).and Include the following segment values:Cycles,shelf temperature,vacuum and safety pressure
● All the equipment can be recorded in real time and the corresponding freeze-drying curves and data tables can be generated after the end.The records of all data and curves comply with the corresponding regulations and standards.
● It has hierarchical management authority,hierarchical management allocation authority and usage process tracking authority
● Remote System
O Fully support 2G/4G/GSM/Wi-Fivarious connection modes
o Users can remotely view all data on the device and operate it
o Technicians can remotely perform maintenance and fault detection on equipment,and can remotely guide and train users
o Can remotely upgrade and change the system of the equipment
(Optional)Sufficient amount and time for the program to run itself
User function customization
Can be customized and modified according to user needs
Sterilization method
HzOz/steam sterilization
Note:”/”optional.Pilot models can be customized according to user needs

The 16S V3-V4 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V3-V4 amplicon libraries to be used for next-generation sequencing on Illumina platforms. All molecular reagents including primers, enzyme mixes, indexes, and buffers are provided. Instructions for PCR clean up with the AMPure XP Magnetic Beads (supplied by customer) are also included for rapid purification of nucleic acid products generated at two steps of the workflow. The library prep workflow could be used for purified DNA inputs from different sources including stool, soil, water, saliva, plant, urine, skin swab, vaginal swab, cheek swab, nasal swab, plasma/serum, tongue swab, gum swab, and others.
The 16S V3-V4 Library Preparation Kit for Illumina has a streamlined procedure that reduces the handling time such that the library prep procedure can be completed in approximately 4 hours (see diagram below). Input DNA is first subjected to targeted PCR to amplify the V3-V4 region of the DNA encoding 16S rRNA. The post-PCR reaction is then cleaned up using AMPure XP beads. Dual index primers are then added using a limited-cycle PCR. The indexed amplicons flanked by 5′ and 3′ barcoded adaptors are then cleaned using AMPure XP beads. The libraries are then ready for quantification, pooling and sequencing.
Details
Minimum amount of starting material:
2.5 µL of DNA (5 ng/µL)
Time to complete library preparation:
4 hours
Storage Conditions and Product Stability Norgen’s 16S V3-V4 Library Prep Kit for Illumina is shipped as one kit box (for the 24 prep kit) or two sub-component kits (for the 96 prep kit). All kits should be stored at -20°C upon arrival.
All kit components should remain stable for at least 1 year when stored at the specified storage conditions.
DBCO-NHCO-PEG5-acid is an analog of DBCO-Acid with a hydrophilic PEG spacer arm, which improves water solubility. This reagent is a non-activated building block with enhanced solubility in aqueous media and can thus be used to derivatize amine-containing molecule through a stable amide bond. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
