Your product may be registered under a different trade name. After selecting the desired product, you must set the parameters by which you want it to be defined, in case this product has varieties. Select volume or dimensions to get the price. Now you can press "order".

To see the price of the product you want, you must first specify the volume, dimensions or other parameters that apply to it. When a product has several varieties, dashes are initially displayed in the price, because not all prices of the individual varieties of this item can be displayed at the same time. After you select a parameter, the price becomes visible for the corresponding type.

This case study is only valid when ordering chemical reagents that cannot be sent by a courier service that does not have a license to transport dangerous goods, such as the reagents themselves. Our refusal to send chemicals by Econt or Speedy is because the couriers themselves refuse to take such cargoes, due to lack of ADR. Therefore, such orders are fulfilled through Transpress or another shipping company meeting the requirements.
