A laboratory mixer is a great time and energy saver for any health care facility, testing service or lab. These devices come with a variety of different designs and options, ensuring you will have just the equipment you need to keep your lab running efficiently and smoothly, even after hours when the technicians have all gone home for the day.
Lab mixers are specifically designed to constantly and consistently move liquids within test tubes, flasks or vials, in a controlled and even fashion. This is typically a gentle rocking motion that can be adjusted or stays at a constant cycle per minute. Standard units offer 24 rocking cycles per minute, keeping liquid moving but without creating splash or excessive agitation of the contents. This gentle and continuous motion prevents solidifying or separation of the liquids or suspensions in the tubes even if staff isn't present in the vicinity.
There are several options with regards to the actual design and capacity of various laboratory mixers and tube rockers. Basic models offer a single rack for test tubes or vials, typically holding between 8 and 15 standard sized test tubes. Dual rack models will double the number of test tubes that can be loaded onto the lab mixer, ideal for larger facilities where equipment and space are in high demand.
These highly useful pieces of equipment come with both 110V and 220V power requirements so they can be used in all types of lab, industrial and health care environments. Some may also use 240V power so it is important to check what type of system you want before making a purchase.
Since cleaning, keeping equipment sterile and germ free, as well as providing maintenance in the lab setting is so essential, look for laboratory mixers that are simple and easy to work on. Many of the new models have a reversible pad for holding the test tubes or flasks, allowing you to quickly change the pad if a spill occurs. In addition the durable and lightweight material used in the pad can be put in the autoclave, allowing for sterilization of the entire surface area without the need for manual cleaning. The pads remove easily with simple screws at each end, making this an easy task even if it needs to be done frequently.
For those specialized labs and facilities that may need more than a basic model there are options to go with a rotator or laboratory mixer that also provides an orbital rotation. These have variable RPM settings that adjust based on the data the user enters. Typically the timer will have options for reciprocating settings, allowing pre-set programs or user defined programs for each use. Rotation angles will vary based on the specific model as well the actual options available with the mixer.
Since this is a piece of equipment that tends to be used almost constantly, getting a very quiet motor is essential. You lab mixer will also need to have non-skid feet or base to prevent the device from moving about on the counter or surface area of the lab when in use.
