Are you in the market for a reliable, low-maintenance centrifuge? Look no further than the hand crank centrifuge! This ingenious device is designed to effectively spin liquids and other substances quickly and with incredible accuracy. Read on to learn more about this amazing tool and its many uses.
Hand Crank Centrifuge Basics
A hand crank centrifuge is a type of laboratory equipment used to separate particles in a liquid sample.
It works by spinning the sample at high speeds, which causes the heavier particles to settle out and the lighter particles to stay suspended in the liquid.
Hand crank centrifuges are simple and cost-effective, and can be operated by laboratory personnel after getting acquainted with its basic operations.
It is ideal for quickly settling suspended solids from small samples at speeds up to 3,000 rpm. This makes it perfect for analytical or clinical procedures that require centrifugation.
Types of Hand Crank Centrifuges Available
The L-K Industries Hand-Crank Centrifuge is a light weight, portable oil centrifuge designed to fit finger (A), pear-shaped (B) or short cone (D) containers.
The Robinson Hand Crank Centrifuge includes a die-cast aluminum body and can be securely mounted to a workbench using the built-in mounting bracket.
Industrial centrifuges are classified into two main categories namely sedimentation or filtration type centrifuges. Sedimentation centrifuges use centrifugal force to separate solid particles from liquids, while filtration centrifuges are used for separating solids from liquids and gases.

How to Make a Hand Crank Centrifuge
A hand crank centrifuge is a single speed machine consisting of die casted parts, a steel pinion, and worm drive. It features a removable crank and produces centrifugal force for sediment and water testing.
The design of the gear ratio and throw of the crank produce a smooth, effortless motion. The hand crank centrifuge accepts two buckets which fit tubes up to 15ml.
Additionally, accessories such as rotors and buckets can be purchased to customize the machine for specific applications.
To make a hand crank centrifuge, you will need die casted parts, a steel pinion, and worm drive. You will also need to construct the frame for the machine and attach the components together.
Advantages of Using a Hand Crank Centrifuge
The main advantages of using a hand crank centrifuge are its portability, light weight, and ease of use.
It is also capable of rapid settling of suspended particles and can be securely mounted to a workbench using the included table clamp.
The centrifuge also has a die-cast aluminum body and steel worm with bronze spiral gear set at a 16:1 ratio for increased torque.
Additionally, it is capable of separating fluids, gasses, or liquids based on the density of the subject.
Disadvantages of Using a Hand Crank Centrifuge
The main disadvantage of using a hand crank centrifuge is the limited sample size that can be processed.
Hand crank centrifuges are not able to achieve the same speeds as electric centrifuges, and therefore cannot process large samples.
Additionally, hand crank centrifuges require manual effort to operate, which can be tiring and time consuming.
Tips for Operating Your Hand Crank Centrifuge Effectively
To operate your hand crank centrifuge effectively, it is important to follow safety guidelines and use the machine properly. Here are some tips for operating your hand crank centrifuge:
1. Read and understand the manufacturer’s instructions before using the centrifuge.
2. Make sure that all parts of the centrifuge are securely fastened before use.
3. Do not bump, jar, or move the centrifuge while the rotor is spinning.
4. Instruct all other persons in the area to stay clear of the unit while it is in operation.
5. Ensure that all samples are securely sealed in their containers before placing them in the rotor chamber of the centrifuge.
6. Make sure that all samples are evenly distributed within the rotor chamber to ensure balanced spinning of the rotor and prevent damage to both samples and machine components.
7. Monitor the speed of rotation carefully and adjust as necessary to ensure that it does not exceed manufacturer-specified limits for your particular model of centrifuge machine.
8. Turn off power to the machine after use and allow it to come to a complete stop before opening or removing any parts from it
Troubleshooting Common Issues with Your Hand Crank Centrifuge
If the centrifuge is wobbling or shaking, pull the plug and check for any loose parts. A little vibration is normal, but excessive amounts can mean danger.
First, pay attention to the manufacturer’s recommendations. If you can’t find what you are looking for in the user manual, contact the manufacturer.
Otherwise, check for any loose parts and make sure all tube holders are present and secure.
If the centrifuge begins to shake or wobble, it is off-balance and you should stop it immediately.
