QPrep Liquid Transfer

QPrep automated workstation provides an integrated solution for liquid handling systems. This products is designed to handle laboratory dilutions, liquid transfers, and other dilutions performed in the laboratory. It can also manage the reagent delivery for the large number of samples in multiple configurations. Automation is necessary to handle these hazardous and expensive chemicals for safety in the laboratory. Generally, the QPrep is controlled by PC software, which is user-friendly and it can also be modified and customized according to the end-user preferences. This software possess unique applications and standards.

QPrep can handle spikes of sample with internal standards, used to prepare calibration and conducts serial dilutions with aliquot transfers. Also, it provides precise and consistent addition of reagents. QPrep provides 0.02 ml of accuracy in handling various reagents and the syringe capacity ranges from 5 ml to 25 ml. The reagent flow rate differs from 0.5 to 2 ml/sec for peristaltic pump. The continuous flow of syringe pump speeds up the dispensing with proper accuracy.QPrep Liquid Transfer

 QPrep is capable of handling HF solutions. It contains PTFE coated graphite probe for accurate handling of the vial and easy cleaning. It can also handle multiple sizes and different types of racks at the same time. The combination of syringe pump and peristaltic pump enhances more flexibility, accuracy and speed. This user-specified methodology is driven through the integrated PC software. QPrep can accommodate 6 standard auto sampler racks with an option of customized rack to hold the QC standards. It is configured to accommodate a wide range of ranks and also go the option of HEPA filter enclosure. The product also contains a mobile stand that supports QPrep, reagent bottle and PC. The modular design of the QPrep allows you to optimize storage, transport space, and device integration. This automated system can be relied upon for liquid handling, Sampling, Dilutions without any risk of error and variability.

Laboratory Glassware

Laboratory glasswares are made with borosilicate 3.3, which is highly resistant of all chemicals, organic solvents and salt solutions. The lab ware are heat resistant, thermal shock resistant and they posses mechanical strength to handle those digestive samples in it. The thermal expansion of the glassware between 0-300⁰C is 33 x 10-7⁰ C and its thermal conductivity is 0.0027 cal/cm³. The borosilicate 3.3 can handle temperature up to 240 degree Celsius for proper and continuous usage appropriate laboratory conditions. It can withstand the temperature in and around 400-450 degree Celsius for short term use. Questron are committed to produce accurate glasswares with in-house laboratory ISO 17025:2005 accredited. These glasswares are equipped with the latest materials for calibration, made under well-controlled environment.

Each product of Questron undergoes numerous tests in order to check its handling capacity. They undergo visual inspection followed by dimensional check, calibration test, marking and re-calibration. These tests are implemented before packaging and also during packaging. Questron is ISO 9001:2015 and CE certified company, which conducts periodical internal audits to check the quality of all the products and to ensure that the commitment of quality is experienced by all their customers. All the products produced by Questron are as per ISO standards and as per the requirement of the end users, which is given top list priority.

Laboratory glasswares are general requirement of any lab, thus they need to be given much care while manufacturing. That is why; these are made with chemical and heat resistant for the safety of end users. Lab wares are supposed to be taken proper care in order to maintain the stability of their applications. Customized glasswares are also made according to the requirements of the user. These are tested well multiple times before they are being packaged to ensure any kind of damage to prevent any kind of disaster during its usage.

Qlab Pro

When it comes to the open or closed vessel microwave extraction, microwave synthesis system, microwave digestion, and microwave evaporation Qlab pro offers versatility, productivity and at the same time ensures the safety of the user. The pressure and temperature level of every digestion vessel will be monitored by the system. And this ensures the safety of the users as well as lays out the assurances of a safe digestion. The system is designed by having in mind and understanding the complexity of the sample handling process to assist the analysts to have very accurate samples.

What the Qlabis capable of?

They are the best option to go for when it comes to synthesis, digestion, evaporation, and extraction of samples. The automated functioning ability of the machine helps in accomplishing a safe digestion. A uniform microwave distribution is achieved with the assistance of the 360 degree carousel rotating antenna and with the innovative cavity design. It is quite suitable for all environments as they are PTFE coated which helps them to withstand corrosion. In order to attain the accurate temperature control the microwave power output functions in a gradual increase method. And it has the ability to hold 1200 Watts power output in small increments.

The system in inbuilt with a preloaded EPA and it also abides with all the standard digestion methods. It has the ability to automatically eliminate unusual heating of the vessels. It can with stand a maximum temperature level of 300 degree.

The multi layered safety element factor:

The system comes with a various technology like OPGuard, OSens that make sure of the safety of the users. The excess pressure is vent out by the OPGuard. In case of increased amount in the pressure release or rise of high temperature OSens jumps in to minimize the problem and at the same time send an intimation by activating the alarm.
