PACKING Type: Carboard box

MATERIAL

LBG 3.3 is a borosilicate glass with a minimum content in silica of 80% and a low expansion coefficient (3.3•10-6 K-1) included in the 3.3 borosilicate group, as defined in ISO 3585 standard.

It is used in products where chemical and mechanical resistance is to be combined with resistance to sudden temperature changes.

This particular combination of properties makes this type of glass the most used in labware.

Labbox

In March 2006, we launched our first catalog in Spain with about 10 pages and 200 references of laboratory glassware (beakers, flasks, pipettes, test tubes, etc.) following three commitments: “prices always low”, “fast delivery” and “satisfied or your money back”. That first catalog was followed by another, and another, and so we have today more than 4000 references of material, consumables, equipment and laboratory chemicals. In addition to our own subsidiary in France, we developed a network of distributors in more than 50 countries. We are now more than 40 employees, having several thousands of active clients and sales above 7 million euros. Today, we are proud of being committed to the same principles with which we started this company. We dedicate all our efforts so that our customers can acquire laboratory supplies at fair prices, with a fast delivery and receiving from us the same treatment that we would like to receive from our supplier. OUR MISSION Provide products and services for laboratories around the world at fair prices OUR VISION To be a leading supplier of laboratory equipment
