Shanghai Haozhuang Instrument Co., Ltd. develops the LNB brand ultrasonic cell crusher, which is energy-saving and environmentally friendly, domestically leading, with quality assurance and best quality. Ultrasound is an elastic mechanical wave in the material medium, it is a form of wave, so it can be used to detect physiological and pathological information of the human body, both diagnostic ultrasound. It is another form of energy. When a certain amount of ultrasound is propagated in the organism, the interaction between them can cause the function and structure of the organism to change, that is, the ultrasound biological effect.
The effects of ultrasound on cells mainly include thermal effects, cavitation effects and mechanical effects. Ultrasonic cell pulverizer utilizes the dispersion effect of ultrasonic waves in the liquid to make the liquid cavitation, so as to break the solid particles or cell tissue in the liquid. Ultrasonic cell pulverizer consists of two parts: ultrasonic generator and transducer . The transducer then undergoes longitudinal mechanical vibration. The vibration wave generates a cavitation effect through a titanium alloy horn immersed in a biological solution, and excites the biological particles in the medium to vibrate violently.
Features of Ultrasonic Cell Crusher 1. Automatic frequency modulation and vibration without manual adjustment.
2. There is a temperature protection probe, which can effectively prevent the sample from being damaged due to the temperature increase during the crushing process.
3. The external temperature control unit can be driven by the "normally open / normally closed" switch according to the signal fed back by the temperature probe.
4. The standard probe below 1/2 "can be converted down by MICROTIP to achieve the breaking of trace samples.
5. Probes of different styles such as closed cup (CUP) and continuous flow (FILLCELL) are available for purchase.
6. There are 96-well microplate crushing head and double needle probe (to ensure the parallelism of the experiment) probes are available for purchase.
7. Tracking display output actual effective power.
8. There are nine program memory functions, which are convenient for users to program and call.
9. The "working / intermittent" proportional time can be adjusted to cycle pulse type work, the time range is from 0.5 seconds to 1 hour, improve the crushing effect, and effectively prevent temperature rise.
10. There is a question menu to protect the miniature probe, which can effectively prevent the machine from being damaged by misoperation. The main purpose of ultrasonic cell pulverizer Ultrasonic pulverizer can be used to pulverize animal and plant cells, bacteria, dental spores or tissues. Disperse rare earth and various inorganic mineral powders. Ultrasonic pulverizer is an ideal device to accelerate the reaction speed of chemistry, biology, physics and accelerate liquid degassing. Ultrasonic pulverizers can prepare latex bodies with a size of nearly one-hundredth of a micrometer; homogenize a "hardly miscible" mixture; polymerize some substances and precipitate others.
Ultrasonic pulverizer can achieve multiple functions of extraction, crushing, emulsification, homogenization, suspension, mutation, aerosol, accelerated desolvation, crystallization and preparation of various biological samples under an electron microscope.
Shanghai Haozhuang Instrument Co., Ltd. is a professional laboratory instrument equipment, biochemical instrument equipment, ultrasonic instrument equipment, test box experiment environment instrument equipment manufacturer, research and development, production, sales Haozhuang (LNB) brand instrument-intelligent constant temperature and humidity culture Box, sterile homogenizer, low temperature and constant temperature, welcome to consult and buy!
There are four types of wayfinding signs: identification, directional, informational, and regulatory. As standalone signs, they serve a specific role; as part of the greater wayfinding system, they inform each other.
Here`s what facility managers need to know about deploying each of the primary wayfinding types of signage.
1. Identification
Identification is the most common type of wayfinding signage. They tell a person when they have arrived at their destination. They also serve as general wayfinding landmarks.
Need to get your bearings? Identification signage is there for you. If you`re looking for Sales and you keep seeing signs for Human Resources, you know you`re in the wrong place.
Make identification signs uncluttered and straight to the point. What does the sign signify? Someone should understand it in seconds.
General examples
- Door plaques (Assistant to the Regional Manager)
- Departmental markers (Accounting and Finance; Sales)
- Landmark signage (donor plaque; historical marker)
2. Directional
Directional signage helps people get to where they`re going. It`s an invisible hand guiding them from wherever they are to their destination, one step at a time. They`re best used at junctions and areas without a clear traffic flow.
Anyone unfamiliar with their surroundings benefits from diverse directional signage. It can be as simple as a plaque at each junction sending people left or right. Or, it may be as comprehensive as colored lines on the floor leading people directly to their destination.
Continuity is key for directional signage. If a person becomes lost anywhere between two points using directional signage, it`s immediately invalidated. Picking up the trail again means backtracking or getting lucky.
General examples
- Junction signage (left to cafeteria; right to an exit)
- Colored lines on the floor (blue for marketing; red for sales)
- Directory signage (CEO, 8th floor; HR)
3. Informational
Whereas identification signage marks a particular area, informational signage pertains to the overall facilities. These signs give people broad information they need while navigating.
Informational signage is best placed in an area with broad exposure. Lobbies, waiting rooms, building entrances, and atriums are popular examples. Signage should answer questions before they`re asked. Where are your bathrooms? How late are you open? Do you have an elevator?
Informational signs should be universally understandable at a glance-signs and symbols anyone can understand.
General examples
- Amenities and accommodations (free Wi-Fi; elevators)
- Facilities signage (bathrooms; exits; cafeteria)
- Business information (hours of operation; address numbers)
4. Regulatory
Regulatory signage is a proactive form of wayfinding. It`s focused on safety and liability concerns and sets boundaries-what is and isn`t acceptable in your facilities. It`s used to establish and reinforce rules, safety standards, and privacy expectations.
Regulatory signage is generally big and bold. No frills-only a clear, concise, prominent message. Someone probably won`t open a closet if there`s a [Caution! High Voltage!" sign on the door. Similarly, displaying a [No Pets Allowed" sign means Fido isn`t welcome.
Use regulatory signage wherever it applies and leave no room for ambiguity. A handicap sign sets a clear precedent, just like an [Employees Only" sign on a locked door.
General examples
- Rules and regulations (no smoking; no firearms)
- Compliance standards (ADA accessibility; high voltage sign)
- Access control (no entry beyond this point; employees only)
Combining wayfinding signage
Every type of wayfinding signage can and should be used with every other. Regulatory signs should keep people out of restricted areas as they follow directional signage to their destination. Identification signage should tell someone where they are, so they can follow directional signage to where they want to be. Informational signage-coupled with regulatory signage-needs to set behavior expectations in your facilities.
Additionally, all signage should be simple. Regardless of its purpose, someone should be able to look at a sign and known in seconds what it says, as well as what it means in relation to wayfinding.
Whatever the information, make sure you have the right mode of delivery. The simpler your signage and the more cohesive it is across all four types, the more effective it will be for anyone using it.
