Description

Molecular sieves are used to adsorb trace amounts of water in solutions and are designed for the synthesis of oligonucleotides. They are intended for synthetic environments with water content below 10 ppm, while ensuring that no dust, fuzz, or other impurities affect the synthesis process. We recommend using 2g of molecular sieve for 50-250ml reagent bottles, 5g for 250-500ml reagent bottles, 10g for 500-1000ml reagent bottles, and 20g for 1000-4000ml reagent bottles. Since we typically use acetonitrile and tetrazole with very low water content, you can use them in synthesis after adding the molecular sieve for at least one hour. However, if acetonitrile and tetrazole have been stored for an extended period without proper sealing, please add the molecular sieve at least two days in advance. The main purpose of our molecular sieve is to maintain low water content in the synthesis reagents, and it is essential to ensure the sealing of the reagent bottles during the synthesis process.

Specifications

• We recommend TP-2 for 50-250ml, TP-5 for 250-500ml, TP-10 for 500-1000ml, and TP-20 for 1000-2000ml. 

Instruction

The molecular sieve is vacuum-sealed, and care should be taken when opening it to avoid puncturing the packaging film. Check for any damage to the packaging film, and then place it inside the reagent bottle. Ensure that the pipette used for synthetic reagents does not puncture the molecular sieve packet, and maintain the sealing of the reagent bottle during use.
