Product Catalogue

www.qtechcorp.com [email protected] Welcome to Questron Technologies With immense pleasure we welcome you to our new catalog for 2018-19. At Questron Technologies we have strived hard to identify the gaps in the market space and the requirements of research fraternity. Biotechnologists at the heart of operations have ensured the requirements being fulﬁlled with right product with right quality and most importantly at the right cost. With the same Zeal we wish to continue the same forever.

Our Raw Material :

Ÿ We use low expansion Borosilicate 3.3 as per ASTM E-438 Type –I.

Ÿ Borosilicate 3.3 is highly resistant to almost all Chemicals, salt solutions and other organic solvents .

Ÿ The labware are highly heat resistant, high resistance to thermal shock & high mechanical strength.

Ÿ Thermal expansion between 0-300/°C is 33 x 10-7/°C and thermal conductivity 0.0027 cal/cm³/°C/Sec.

Ÿ Borosilicate 3.3 can handle temperature up to 240 degree Celsius for continuous usage under general laboratory conditions , whereas it can withstanding temperature around 400-450 degree Celsius for short term usage .

Accuracy and quality :

Ÿ We are committed to produce highly accurate Labware with an in-house ISO 17025:2005 accredited laboratory, well equipped with the latest equipments for calibration under well controlled environment.

Ÿ Each product undergoes numerous tests right from visual inspection of newly produced material, followed by dimensional checks, caliberation and marking and then recalibration post printing and ﬁnally visual inspections before and during packaging.

Ÿ We are an ISO 9001:2015 and CE certiﬁed company and we conduct periodical internal audits to keep check over all the quality systems implemented and ensure our commitment to quality is well experienced by our customers.

Ÿ All the products are produced as per ISO/DIN/ASTM standards and requirement of the end user is kept at ultimate priority.
