What is the purpose of the rubber stopper sleeve on a multisample needle?
Wiki User
∙ 13y ago
The rubber stopper sleeve on a multisample needle helps to prevent leakage of blood or other fluids during sample collection. It also helps to maintain sample integrity by creating a barrier between the needle and the sample, reducing the risk of contamination.

What is the hole in the rubber stopper for?
The hole in a rubber stopper is used to allow for the insertion of glass tubing or a thermometer into a container without disrupting the seal created by the stopper. This allows for measurements or additions to be made to the container while maintaining a closed system.
When magnesium reacts quickly with hydrochloric acis to produce hydrogen gas in a glass tube with a rubber stopper why would the rubber stopper burst of?
The reaction between magnesium and hydrochloric acid produces hydrogen gas, which builds up pressure inside the closed glass tube. If the pressure exceeds the strength of the rubber stopper, it will burst off to release the built-up pressure and prevent the glass tube from breaking due to the increased pressure.
Why are the tubes sealed with rubber stopper rather than left open?
To avoid loss of substances.
What happens to the number of revolutions of a rubber stopper as the radius of rotation decreases?
As the radius of rotation decreases, the number of revolutions of a rubber stopper increases. This is due to the conservation of angular momentum - with a smaller radius, the rotational speed must increase to maintain the same angular momentum.
What is the function of a rubber bung?
A rubber bung (also called rubber stopper) is used in the laboratories for test tubes, flasks (made of glass usually). Bungs also used by winery industry for the wine bottles. A bung must fill well as a stopper. The bungs are of many sizes. Rubber bung can have one or more hole(s) for plugging in tube depending on the specification of the procedures. In chemical laboratory, to prevent the liquid chemical leaks or escape the container, we need the rubber bung that fit tightly to the container's open, therefore, the dimension of the rubber bung is concerned. These are some of the sizes that are commonly seen in chemical laboratory
When pushing a needle through the rubber stopper of a vial there is a potential of?
When pushing a needle through the rubber stopper of a vial, there is a potential risk of contamination if proper aseptic technique is not followed. It is important to ensure the needle is sterile, the stopper is disinfected before puncturing, and proper hand hygiene is maintained to prevent introducing microorganisms into the vial. Additionally, care should be taken to avoid needle stick injuries.
Where can you buy a rubber stopper?
You can buy an rubber stopper at widget-co.com. They are not that expansive ethier
What is the volume of rubber stopper?
The volume of a rubber stopper can vary depending on its size and shape. To find the volume of a rubber stopper, you can use the formula for the volume of a cylinder or sphere, depending on the shape of the stopper. Measure the dimensions of the stopper and plug them into the appropriate formula to calculate the volume.
Would a rubber stopper float in water?
No, rubber is denser than water, so a rubber stopper would sink in water.
Is the density of rubber stopper is denser than the density of water?
No, the density of a rubber stopper is less than the density of water. Rubber has a lower density compared to water, so a rubber stopper would float on water.
When magnesium reacts quickly with hydrochloric acis to produce hydrogen gas in a glass tube with a rubber stopper why would the rubber stopper burst of?
The reaction between magnesium and hydrochloric acid produces hydrogen gas, which builds up pressure inside the closed glass tube. If the pressure exceeds the strength of the rubber stopper, it will burst off to release the built-up pressure and prevent the glass tube from breaking due to the increased pressure.
When a rubber stopper has a mass of 8.46g was immersed in a graduated cylinder containing 25 ml of water the water rose to 30.9 ml Calculate the densityof the rubber stopper?
The volume of the stopper can be calculated by subtracting the initial volume of the water from the final volume. In this case, the volume of the rubber stopper would be 30.9 ml - 25 ml = 5.9 ml. Now, divide the mass of the rubber stopper (8.46 g) by its volume (5.9 ml) to find its density. Density = Mass/Volume, so the density of the rubber stopper would be 8.46g / 5.9ml = 1.43 g/ml.
What is the average life expectancy of a rubber stopper?
This is very variable and depends on: - type of rubber - temperature - pressure on the stopper - the liquid in contact - other conditions of use
What is the use of rubber stopper in laboratory apparatus?

How do you replace rubber brake stopper on a 2001 Nissan Xterra?
remove the pedal arm pin so that you can freely move the pedal and have an access to the rubber stopper slots.
What is the use of beaker cover?
A beaker cover is used to prevent contamination of the contents inside the beaker during storage or when the beaker is not in use. It helps to keep the contents clean and free from dust, debris, or other contaminants. Additionally, it can also help prevent accidental spills or evaporation of volatile substances.
