Centrifugation - Wikipedia

However, depending on the centrifuge model used, the respective angle of the rotor and the radius may vary, thus the formula gets modified. For example, the Sorvall #SS-34 rotor has a maximum radius of 10.8 cm, so the formula becomes R P M = 299 g r {\displaystyle RPM=299{\sqrt {g \over r}}} , which can further simplify to R P M = 91 g {\displaystyle RPM=91{\sqrt {g}}} .

The Bottle Centrifuge. shown schematically in Figure 1. Equations for correction factors 5 1 for the settling rates uc and ug in Equations (1) and (4) are summarized in [8]. will also improve the flow rate at acceptable separation efficiency.

A Technique for the Measurement of in vitro Phospholipid ...

Add 1.5 ml of chloroform:methanol 2:1 and vortex for 10 sec. The chloroform dissolves the lipids and the methanol maintains the proteins precipitated. Centrifuge 10 min at 3,500 rpm to allow protein precipitation and separation from soluble lipids.

FLSmidth - Decanter Solidbowl Centrifuge

The Decanter solidbowl centrifuge is commomonly used to seperate, clarify, or classify solid particles from liquid. The solidbowl centrifuge is often used in processing chemical, food, mineral, rendering, and both industrial and municipal wastewater industries.

POTASSIUM ION CONCENTRATION - Di-Corp

1. In order to balance the centrifuge, measure 14 mL of fresh water in the other centrifuge tube and place it into the centrifuge. 2. Add 4.0 mL sodium perchlorate to 10.0 mL of filtrate to be tested in the centrifuge tube. A white precipitate, which forms immediately, indicates the presence of potassium. 3.

Desalting/Buffer Exchange and Concentration for Affinity ...

The sample should be fully solubilized. Centrifuge or filter (0.45 µm filter) immediately before loading to remove particulate material if necessary. Buffer exchange. Protein solubility often depends on pH and/or ionic strength (salt concentration), and the exchange of

Centrisart® D-16C Refrigerated Benchtop Centrifuge

The powerful centrifuge provides a maximum speed of 15,000 rpm and a capacity of 24 × 2 ml. Microcentrifuge A-14C is ideal suited for nucleic acid isolation and purification using spin-columns and concentrating biological samples using Sartorius Vivaspin® 500 units.

Gabbioneta™ RL – Pompe centrifuge API 610 type OH2 ...

Les pompes process de la gamme Gabbioneta™ sont basées sur une conception de type hydraulique sans recirculation interne pour répondre aux conditions de très bas débit.

How to increase the concentration of DNA in solution?

Addition of too much sec-butanol can result in complete loss of the water phase into the sec-butanol layer. If this happens, add 1 ⁄2 vol water back to the sec-butanol, mix well, and spin.

Polymerase Chain Reaction Protocol

Centrifuge the primer block on low speed setting (Jouan Centrifuge - 190 x g for 20 sec, Program 1 (1000 rpm for 20 sec). Using the 8-channel pipettor, transfer 1.4 L of the forward primer of primer set #1 to column 1 of the PCR-ready MasterMix plate.

22.vortex for 3 sec. Centrifuge for 3 mins. Carefully transfer ~145ul top aqueous layer to a new tube. 23.Add 300ul 100% ice-cold ETOH on dry ice for 20-30mins.Centrifuge at 18,000rpm at 4C for 30 mins.

Bios 311 Day 2 Lab Protocols - Rice University

Centrifuge the sample at 10,000xg for 20 minutes at 4°C (table top centrifuge); the longer centrifugation ensures the pellet packs "tight" to the bottom of the tube. 8. Remove the supernatant and seal the tube with Parafilm; store the pellet in a screw cap bottle at -20°C until the next lab.

Laboratory Centrifuges Specifications | Engineering360

Micro-centrifuges are made for spinning 1 to 2 ml plastic centrifuge tubes at speeds up to 12-or-13 thousand rounds per minute. They have very small, light rotors in them (the rotor is the part of the centrifuge that contains the holes for the sample tubes), which speed up and slow down rapidly.
