A pipette, also known as a pipette gun, is a device used to quantitatively transfer liquids. When conducting research in analytical testing, a small or trace amount of liquid is generally removed with a pipette. Pipettes can be divided into gas piston pipettes (Air-displacement pipette) and external piston pipettes (Positive-displacement pipette) according to the principle. Gas piston pipettes are mainly used for standard pipetting, and external piston pipettes are mainly used to handle special liquids such as volatile, corrosive and viscous. Many people ignore the correct use of pipettes and some of the details.

Ordinary steering wheel locks are mainly divided into three types: The first type is a top hook lock with 2 hooks, a folding lock or a telescopic lock belongs to this type; the second type is a baseball lock shaped like a baseball bat; the third type is one end. T-lock on the instrument panel with the steering wheel on the other end. Their working principle is to lock on the steering wheel, and use the protruding part to make the steering wheel unable to rotate to achieve the purpose of anti-theft. But they have a fatal flaw: sawing or cutting one or two notches on the steering wheel, the ordinary steering wheel lock can be removed from the gap, and its protection is lost. In order to reduce the damage to personnel in the event of an accident, the car manufacturer made the steering wheel very weak. With a common hand saw, it takes just over 20 seconds to saw one or two gaps on the steering wheel. Therefore, the ordinary steering wheel lock, for the car thief, is in vain.
Therefore, the steering wheel lock that can effectively prevent theft must be able to protect the steering wheel. For example, the full-face steering wheel lock introduced in the UK has a high anti-theft performance. The steering wheel lock covers the entire steering wheel so that the car thief cannot destroy the steering wheel. Most of the products sold in Taiwan are half-hood steering wheel locks. This type of lock uses a titanium alloy cover to cover the middle of the steering wheel, and then locks the top hook lock or T-lock through the titanium alloy cover to the steering wheel. The car thief can't cut the steering wheel and remove the lock. Although such steering wheel locks are expensive, bulky, and inconvenient to use, most of Taiwanese car owners still buy such half-hood steering wheel locks because Taiwan steals 50,000 cars a year (more than 200,000 new cars are sold each year). .
A new generation of steering wheel lock ---- armor lock, opened a steering wheel lock design new concept: with two fixed posts, the steering wheel lock is fixed on any one of the steering wheel, and then with two steel armor The cover covers the spoke. It is impossible for the car thief to destroy the spoke column by sawing or cutting, and it is impossible to remove the armor lock without destroying the spoke. Since the full-cover and half-cover steering wheel locks only cover the steering wheel on the front side, the car thief can still destroy the steering wheel from the back; while the armor lock protects the steering wheel at the locked front and rear, the car thief can't destroy it from any direction. The steering wheel at the lock, so the safety of the armor lock is higher than the full-face and half-cover steering lock. Moreover, the armor lock only protects the steering wheel at the lock, so the volume is not large, the weight is almost the same as the ordinary steering wheel lock, and it is not necessary to use expensive titanium alloy to reduce the weight, which greatly reduces the cost. In addition, the armor lock is locked with a 12-ball crescent-shaped lock cylinder, and the fragile lock core is covered with a steel cover. With the master key, various professional unlocking tools, drilling, smashing, knocking and other violent methods can not be illegal. Open the lock cylinder. Moreover, the armor lock also cleverly uses the car horn sound alarm. If the lock is broken or the lock is broken by an abnormal method, the horn will be triggered to sound an alarm.
At present, folding armor locks and armor locks with electronic two-way burglar alarms have been introduced on the market. Folding armor locks are not only suitable for cars, but also for vans, large trucks, etc., making the armor locks more widely applicable. The armor lock with electronic two-way anti-theft alarm combines the deterrent effect of the electronic anti-theft alarm with the strong advantage of the armor lock mechanical anti-theft, so that the anti-theft performance of the armor lock is more perfect.
Although the anti-theft performance of other types of anti-theft systems or devices may be good, but the car thief did not know before starting, and then drilled and knocked into the car, making the car look completely unrecognizable. The steering wheel lock of the armor is placed in the most conspicuous place in the car. When the car thief sees it, he will find it difficult to retreat and choose other easy-to-start targets. Therefore, the deterrent effect of the steering wheel lock with high anti-theft performance on the car thief is irreplaceable for the ordinary anti-theft lock. The use of armor locks does not require any modifications to the car, which is important for new cars. Some anti-theft products need to be cut or drilled when installing. If there is a quality problem during the warranty period, the merchant often changes the car as a reason for refusal.
As the polarization between the rich and the poor in society becomes more and more serious, more people will take the risk to steal high-value vehicles. Therefore, the owner should have a good sense of safety and try to park the car in a place where someone is looking after it. If the car is parked unsafe or parked overnight, lock the armor lock on the car. Some people may say that there is no lock that cannot be opened in the world. However, as long as the car thief spends a long time and can not remove the armor lock, the armor lock can effectively prevent theft. Because car theft is risky, if the car thief can't get it in 5 to 10 minutes, they will give up and go to other easy-to-find targets. Remember, don't let your car become a target for car thieves.
Introduction and selection of a new generation of steering wheel locks
At present, the anti-theft measures for vehicles generally rely on electronic anti-theft systems, and the steering wheel lock is only an additional optional anti-theft measure. But as electronic devices used by car thieves become more advanced (such as signal interceptors, decoders, signal jammers, etc.), people are beginning to look for traditional anti-theft measures. The introduction of a new generation of super-anti-theft steering wheel locks makes the new generation of steering wheel locks an increasingly effective means of car theft.
