why use syringe for lube?

Plastic syringe as a container and a tool for tube, which is popular for users. Syringe for lube is popular in users nowdays, the following is the advantage of syringe.

10cc syringe for lube
When empty, the applicator can be refilled with any machine quality grease. It’s a handy applicator enabling pinpoint application of the grease, minimizing the mess. The needle tip is handy for getting just a drop of lube where you need it, such as on contact points on a semiautomatic pistol. the syringe for applying it and the long tip makes getting into smaller places easy and controlling the amount applied.

The analysis of plastic pharmaceutical packaging

Plastic pharmaceutical packaging is containers made exclusively or partially of plastic. Plastic containers are ubiquitous either as single-use or reuseable/durable plastic cups, plastic bottles, plastic bags, plastic syringe, plastic tubes. The entire packaging industry is based on plastic containers or containers with some plastic content (eg plastic coating or when made of composite material), besides paperboard and other materials. Pharmaceutical packaging nowadays relies mainly on plastic food storage containers.

A basic but important distinction is between single-use / disposable and multi-use / durable containers. The former makes up a notable portion of the global plastic waste (e.g. effervescent tablets tubs, food container, most plastic bottles, etc.). Because of the multitude of container applications, the types of plastic vary widely. Because of the material variety (combinations are no exception), the waste will make up a significant portion of plainly visible plastic pollution although some containers like bottles are recyclable.

Plastic has replaced traditional materials like wood, paperboard, and metal for the manufacture of containers because of its price, moldability/formability, durability and light weight.

Desiccant packaging principle

According to the effervescent tablet medicinal properties, the desiccant packaging principle is to place the desiccant in the cap and seal the bottle through the cap. The package has strict requirements on sealing properties, water molecule control, moisture resistance, water vapor transmission rate, and moisture content of the desiccant. The pharmaceutical packaging has achieved the purpose of absorbing water molecules by placing the desiccant in the cap, which requires the material to have good barrier properties to water molecules. Followed by the moisture content of the desiccant and the humidity of the production plant. All of these aspects will lead to the effectiveness of effervescent tablets.
Desiccant packaging principle    

The prescription for effervescent tablets consists of the main drug, diluent, binder, disintegrant, lubricant and other excipients. The diluents, binders, lubricants and other excipients used are the same as ordinary tablets. The appropriate variety needs to be selected according to the preparation process. Unlike ordinary tablets, the disintegrant used in effervescent tablets is an effervescent disintegrant, and the effervescent disintegrant includes an acid source and an alkali source. Commonly used acid sources are citric acid, malic acid, boric acid, tartaric acid, and rich. Horse acid, inorganic mineral acid (hydrochloric acid), etc.; commonly used alkali sources are sodium hydrogencarbonate, sodium carbonate and a mixture of the two. The ratio of acid to base has a significant effect on the preparation and stability of effervescent tablets. It is generally believed that the amount of acid exceeds the theoretical amount, which is beneficial to the stability of the effervescent tablet and the improvement of the mouthfeel.

paste syringe for dogs

Probiotic paste available in 30ml and 60ml easy to use calibrated syringes.
At present, there are two main problems in the veterinary syringe rubber stopper guiding cylinder:
1. The gap between the outer wall of the rubber guide guiding cylinder and the inner wall of the syringe and the smoothness and compression ratio of the rubber plug during operation and the inner wall of the rubber guiding cylinder. The inner surface of the rubber plug guiding cylinder is too low, and the friction coefficient is too large, so that it is easy to produce particles on the rubber plug; the inner diameter of the rubber guiding cylinder is too small, which will affect the compression ratio of the rubber plug, and the compression ratio is too large, which not only destroys the characteristics of the rubber plug. It will also increase the inner wall friction coefficient, resulting in the production of rubber stopper particles.
2, for anaerobic drugs, before the plug, must be filled with inert gas nitrogen, so it must be considered that the plug is not affected by the presence of nitrogen gas holes because of the presence of nitrogen gas holes caused by the rubber plugs through the rubber plug guide tube and nitrogen holes Scratches are generated to produce particles, so consider how to scientifically and reasonably arrange the nitrogen holes and define the inner diameter of the nitrogen holes.
there are also 5ml and 10cc syringe for intramammary.
