Description

Grinding beads used during DNA and RNA isolation can introduce nuclease or nucleic acid contamination into molecular biology workflows. These 800 micron molecular biology grade silica beads are made from acid-washed beads and undergo additional processing by baking. They are then aseptically packaged in an RNase/DNase-free bottle.

The product supplies 200 g of 800 µm silica grinding beads for laboratory molecular biology applications. The additional processing and controlled packaging address the contamination concerns associated with using grinding beads in DNA and RNA isolation workflows.

FAQ

What are 800 micron molecular biology grade silica beads?

They are 800 µm silica grinding beads made from acid-washed beads and further processed by baking. The beads are aseptically packaged in an RNase/DNase-free bottle for laboratory molecular biology applications.

What is the size of the silica grinding beads?

The specified bead size is 800 µm, which is also expressed as 800 microns.

How much product is supplied?

Each package contains 200 g of molecular biology grade silica beads.

What material are the grinding beads made from?

The product is identified as silica grinding beads. The safety information lists amorphous silica, sodium oxide, calcium oxide, and magnesium oxide as components.

How are the molecular biology grade silica beads processed?

The molecular biology grade beads are made from acid-washed beads and receive additional processing by baking. They are then packaged aseptically in an RNase/DNase-free bottle.

Are the beads packaged in an RNase/DNase-free bottle?

Yes. The product information states that the beads are aseptically packaged in an RNase/DNase-free bottle.

Can these silica beads be used during DNA isolation?

Yes. The product information identifies DNA isolation as a molecular biology workflow in which grinding beads may be used and where nuclease or nucleic acid contamination must be considered.

Can these silica beads be used during RNA isolation?

Yes. The product information identifies RNA isolation as a molecular biology workflow in which grinding beads may be used and where nuclease or nucleic acid contamination must be considered.

Why is additional processing important for molecular biology grinding beads?

Grinding beads used for DNA and RNA isolation can be a potential source of nuclease and nucleic acid contamination. These beads are made from acid-washed beads, further processed by baking, and aseptically packaged in an RNase/DNase-free bottle.

What is the appearance of the silica beads?

The product is a white, odorless solid.

How should the silica grinding beads be stored?

Store the product in a cool, well-ventilated place. The recommended storage temperature should be confirmed on the product label.

Are the silica grinding beads classified as hazardous?

The safety information lists the product as not classified under the applicable GHS US classification and states that no hazard labeling is applicable.

Are the silica beads regulated for transport?

The product is listed as not regulated for transport by road, sea, or air.

Are these beads intended for laboratory use only?

Yes. The recommended use is laboratory use. The product is not intended for drug, household, or other uses.

Is a 96-well plate dispenser included for alpha-synuclein seed assays?

No. The product information states that a dispenser for filling 96-well plates for this assay is under development. It is not listed as part of the 200 g silica bead product.
