半球封VS拉丝封

文/ 发布于2020-11-20  浏览数量:
There are two common methods for sealing glass ampules; the “Tip Seal Method” and the “Pull Seal Method.”  This paper explains the differences, benefits, and constraints of using each method.
玻璃安瓿的封瓶方法有两种,即“半球封法”和“拉封法”,本文阐述了每种方法的区别、优点和限制条件。
 

Tip Seal Method
半球封

 
The Tip Seal Method (a.k.a. Bead Seal Method) involves melting the glass at the top of the ampule downward.  The ampule is constantly spinning during the sealing process to create a rounded, hemispherical seal.
尖端密封法(又称半球封或珠封法)是将安瓿顶部的玻璃向下熔化。安瓿在密封过程中不断旋转,形成一个圆形的半球形密封。
 
The Ampulmatic-10 Ampule Filling/Sealing System utilizes the Tip Seal Method, as it creates a uniform, attractive and stronger seal than the Pull Seal Method.
Ampulmatic-10(简称A-10)安瓿灌装密封系统采用尖端密封法,因为它比拉式密封法产生均匀、有吸引力和更强的密封性。
 
 

Pull Seal Method
拉丝封

 
The Pull Seal Method melts the glass in the middle of the ampule neck.  When the glass is melted, the top of the neck is pulled off with a small amount of thin glass melted to create the seal.
拉封法在安瓿颈部中间熔化玻璃。当玻璃熔化时,颈部的顶部会被少量熔化的薄玻璃拉下,形成密封。
 
Ampules can also be called ampoule, ampul, or ampulla.

Tip Seal(半球封)    Pull Seal(拉丝封)

Appearance
外观


Seal  is  hemispherical,  with  a  uniform height and shape
封口为半球形,高度和形状均匀

Seal is pointed at the tip, irregular, sometimes a bead of glass is sharp or hanging.
封口是尖的,不规则的,有时玻璃珠是尖的或悬的。

 

Seal Strength/Integrity
密封强度/完整性


Seal is made of thicker glass, very strong and uniform.
密封是用较厚的玻璃制成的,非常坚固均匀。

Seal  is  made  from  thinner,  stretched glass that is not uniform.
密封是由较薄的拉伸玻璃制成的,这种玻璃不均匀。

 
 

Ampule Height
安瓿高度


Each ampule is the same consistent height.  The finished ampule will be taller with this method, unless shorter ampules are chosen.
每个安瓿的高度一致。用这种方法制成的安瓿会更高,除非选择较短的安瓿。

The height of the ampule is dependent on where the glass was heated/pulled.  The height of the ampules varies.    The finished ampule will be shorter with this method.
安瓿的高度取决于加热/拔出玻璃的位置。安瓿的高度各不相同。用这种方法制成的安瓿会更短。

 


Technical Ability
使用人员技术能力


When using the Ampulmatic-10 System, the technician simply places empty ampules into the carousel and removes the sealed ampules. There is very little skill or training necessary.   Setting the flame  condition  and  dwell  time  in  the flame initially is typically completed in 5 minutes or less.
当使用Ampulmatic-10(简称A-10)系统时,技术人员只需将空的安瓿放入旋转样品载具盘并取出密封的安瓿。几乎没有必要的技能或训练。最初设置火焰条件和火焰停留时间通常在5分钟或更短时间内完成。

When performed manually, Pull Sealing requires  a  trained  technician  with excellent hand-eye coordination and glasswork experience.
当手动操作时,拉丝密封需要经过培训的技术人员,具有良好的手眼协调能力和玻璃加工经验。
 

Equipment Variability
设备适应性


The Ampulmatic-10 System is highly customizable for each unique application.
 It is designed to accommodate sizes ranging from very small “onion skin” tubes to large 100 ml ampules. Many custom options   are   available   including   NMR tubes,  test  tubes,  and  chilled  ampules. The  Ampulmatic-10  System  was designed  to  be  easily  adjusted  for different ampules sizes and liquids.
Ampulmatic-10(简称A-10)系统是高度可定制的每一个独特的应用。它的设计尺寸从非常小的“洋葱皮”管到100毫升大的安瓿。许多定制选项可供选择,包括核磁共振管,试管,和冷冻安瓿。A-10系统的设计是为了方便调整不同的安瓿尺寸和液体。

Most pull seal machines are built for very large-scale production and are not designed for a wide range of applications. Often they are limited by a smaller range of ampule sizes and dimensions and can be difficult to adjust between different sizes.
大多数拉丝熔封机是为大规模生产而制造的,并不是为广泛的应用而设计的。通常它们受到安瓿尺寸和尺寸范围较小的限制,很难在不同尺寸之间进行调整。

 

Safety
安全


When using the Ampulmatic-10 System, the sealing process is automated. This reduces safety concerns of an operator handling a torch or putting their hands/ clothes near the flame.
使用Ampulmatic-10(简称A-10)系统时,密封过程是自动化的。这减少了操作火焰喷头或将手/衣服靠近火焰的操作员的安全问题。

When performed manually, the operator must spin the ampules, pull the top off, and sometimes handle the torch. This procedure puts the operator at risk for accidents, burns, and ampule breakage.
当手动操作时,操作员必须旋转安瓿,拔下瓶盖,有时还需要处理焊枪。这个程序使操作者面临事故、烧伤和安瓿破损的危险。
 
 
 
The Ampulmatic-10 System is a bench scale ampule sealer with optional Liquid Filler and Purge Gas Injector accessories. The base unit sealer automates the sealing process. This System utilizes the tip seal method, and spins the ampules while sealing to create a consistent, hemispherical seal on every ampule. The ampule dwell time (time in the flame) can be easily changed by the turn of a dial. The sealer is designed for a wide range of ampule sizes, from very small “onion skin” 1 ml ampules to large 100 ml ampules.
该Ampulmatic-10(简称A-10)系统是一个小型安瓿封口机可选液体填充和吹扫气体注射器配件。基本单元封口机自动完成封口过程。该系统采用尖端密封方法(也称半球密封或珠封法),在密封的同时旋转安瓿,在每个安瓿上形成一致的半球形密封。安瓿停留时间(火焰中的时间)可以很容易地通过转动刻度盘来改变。封口机设计用于各种规格的安瓿,从非常小的“洋葱皮”1毫升安瓿到100毫升的大安瓿。
 
The optional accessories automate the process of filling, purging and sealing the ampules. The Liquid Filler accessory fills volumes ranging from 0.1 ml to 22 ml with a relative standard deviation of 0.5%. The Purge Gas Injector fills the ampule with inert gas before sealing, reducing the residual oxygen concentration to 1%. This is especially useful when sealing volatile substances.
可选配件使安瓿的灌装、清洗和密封过程自动化。液体填充附件的填充量为0.1 ml到22 ml,相对标准偏差为0.5%。在密封前,吹扫气体注入器用惰性气体填充安瓿,将残余氧气浓度降低到1%。这在密封挥发性物质时特别有用。
 
The Ampulmatic-10 System is small enough to be placed on a cart or inside a laminar flow hood. It is highly adaptable and customizable.  Bioscience, Inc. personnel have worked with customers to solve a variety of difficult applications. We can perform testing in our laboratory to determine sealing procedures for your unique application.
