Ekstraktion

The LABSOLUTE® extraction thimbles are made of 100 % cellulose. They have a high mechanical stability and are free from binders. The extraction thimbles have a wall thickness of about 1 mm and a pore size of approximately 5 µm. They are perfect for all kind of Soxhlet extractions as well as for the separation of liquid and solid particles out of air and gases.

Neutral and fat free. With excellent retention capacity. Ash content <0.1 %.

Extraction and clean-up mixtures for sample preparation in the pesticide analysis of vegetable foodstuffs according to EN 15662 using GC/MS or LC/MS after acetonitrile extraction and purification using the dispersive SPE-QuEChERS method.

The samples are first extracted with Mix A. Purification is done with one of the following mixtures:

• Mix B (Clean-up mixture for fruits and vegetables with low fat content, e.g. apples, strawberries)
• Mix C (Clean-up mixture for fruits and vegetables with high fat content, containing oil/wax, e.g. avocados)
• Mix D (Clean-up mixture for moderately chlorophyll/carotenoid-containing fruits and vegetables, e.g. carrots, salad)
• Mix E (Clean-up mixture for fruits and vegetables with high chlorophyll/carotenoid content, e.g. sweet peppers, spinach)

• Mix A contains a bag with the required amount of mixture and a 50 ml empty tube
• Mix B, C, D and E are pre-weighed into a 15 ml tube

Extraction apparatus, Soxhlet-pattern. With Dimroth condenser and round-bottom flask.
Made of Duran^® tubing.

• Fat determination in food and feed
• Determination of binder content in asphalt
• Analysis of soil contaminants
• Determination of additives in rubber and elastomers

Manufactured in pure cellulose according to DIN 12449.
